Understanding Mosquito Net Specifications: Mesh Count and Denier Explained

CombinationProfileBest For 75D / 156 meshStandard LLIN, balanced weight and durability Most government tenders, home distribution, standard stockpiles 100D / 156 meshHeavy-duty, tear-resistantRefugee camps, long-term shelters, high-wear sites 50D / 156 meshUltra-light, lower costAir-freight emergency response, short-term use 75D / 100 meshStandard yarn, coarser weaveLow-cost retail, not for malaria control tenders

 

Common Specification Misconceptions

• Misconception 1: "Higher denier is always better." Thicker yarn increases weight and shipping cost. For most African distribution programmes, 75D provides the optimal balance - 100D is only justified for high-wear camp environments.
• Misconception 2: "Higher mesh count is always better." Mesh above 156 reduces airflow and can make sleeping uncomfortably hot in tropical climates. 156 is the WHO-validated sweet spot between protection and comfort.
• Misconception 3: "All insecticidal nets are LLIN." A net must use WHOPES-recommended insecticide at the correct dosage AND retain efficacy after 20 washes to qualify as LLIN. Ordinary treated nets lose effectiveness after a few washes.

Quick Selection for Emergency Mosquito Nets
Work through these three questions to identify the right model:

1. Where will it be used? Refugee camps and fixed shelters with bed frames → Model A (rectangular LLIN). Homes with only a ceiling hook → Model B (conical). School gyms or warehouses with no suspension points → Model D (self-supporting). Maternal and child health centres → Model E (baby size). Malaria zones with confirmed pyrethroid resistance → Model C (PBO-enhanced).
2. Is insecticide treatment required? Red Cross, UN and humanitarian malaria programmes → LLIN treated (Models A, B, C). General pest control in non-malaria regions, or institutions that treat nets themselves → untreated (Models D, E, or Model A untreated variant).
3. What is the packing and logistics budget? Maximum container efficiency → Model A (100 units/carton, ~15,000 units per 40ft HQ). Lightest air-freight option → Model B (450g, compact fold). Self-supporting for rapid deployment → Model D (heavier but no installation tools needed).

When in doubt, start with Model A. It covers roughly 70% of humanitarian and institutional LLIN procurement cases and matches the WHO standard rectangular LLIN specification.

 

LLIN Mesh and Insecticide for Mosquito Net Manufacturer

Mesh count (holes per square inch)

The standard WHO-recommended mesh is 156 holes per square inch (approximately 24 holes per cm²). This density blocks mosquitoes while allowing sufficient air circulation for comfort in tropical climates. Finer meshes (196 holes/inch² or 30 holes/cm²) are available for regions with small biting midges or sand flies, but reduce airflow and are not needed for standard malaria mosquito control. All our LLIN models use 156 holes/inch² as standard.
 

Insecticide types

• Deltamethrin: The most widely used pyrethroid for LLIN. Applied at 55 mg/m². Odourless after curing. Effective for 3-5 years and at least 20 standard washes. WHO-recommended for malaria control.
• Alpha-cypermethrin: An alternative pyrethroid, applied at 200 mg/m². Available on request for tenders that specify this active ingredient.
• Deltamethrin + PBO: Model C uses Piperonyl Butoxide on the roof panel to overcome pyrethroid resistance in mosquito populations. Recommended for high-transmission zones where standard LLIN efficacy has declined.

 

Construction details

All nets are woven from 100% polyester monofilament yarn. Denier options are 50D (lightest, 20±2 g/m²), 75D (standard, 30±3 g/m²) and 100D (heavy-duty, 40±3 g/m²). Standard LLIN uses 75D. Seams are overlocked for tear resistance. Bursting strength meets ISO 13938-2: minimum 250 kPa for 75D, 405 kPa for 100D. Each net has a production lot number printed on the label for full batch traceability.



 

Scene Selection for Mosquito Net Procurement

Refugee Camps and Fixed Emergency Shelters (Red Cross / UN / NGOs)

Recommend Model A (rectangular LLIN, double bed size). Four corner loops attach to bed frames or shelter beams. The 190 × 180 × 150 cm size covers two people. Deltamethrin treatment provides malaria protection for 3-5 years. Multilingual installation cards (English, French, Arabic, Spanish) are included. This is the standard model procured by Red Cross societies and UNHCR for camp distributions.
 

Barracks and Field Deployments

Recommend Model A in green or navy (institutional colours) for barracks with bed frames, or Model D (self-supporting) for field tents with no anchor points. LLIN treatment protects personnel in malaria-endemic deployment zones. Confirm the unit's bed dimensions and available suspension height before ordering. Custom unit insignia printing is available on the carry bag (not on the net mesh).
 

Dormitories and Station Accommodation

Recommend Model A in navy blue for station dormitories and rest rooms. The rectangular LLIN fits standard bunk beds. For temporary deployment shelters without suspension points, Model D (self-supporting) sets up in seconds. Confirm bed size and whether the dormitory has ceiling hooks or beams before selecting the suspension type.
 

School Evacuation Centres and Gymnasium Shelters

Recommend Model D (self-supporting frame) for school gyms, halls and warehouses where there are no hooks or beams. The pop-up frame requires no tools and no installation training. Nets fold flat for daily storage and redeployment. For schools with fixed beds in dormitory settings, Model A is more cost-effective.
 

Field Hospitals and Medical Clinics

Recommend Model A for patient beds in field hospitals and temporary clinics. LLIN treatment protects patients and staff from mosquito-borne disease. Model E (baby/child size) for paediatric wards and maternal health units. Confirm bed dimensions and whether the net must be compatible with IV poles or medical equipment around the bed.
 

Home Distribution and Community Malaria Programmes

Recommend Model B (conical LLIN) for home distribution where households may only have one ceiling anchor point. The single-point suspension is easier for families to install without tools. Model A is preferred when bed frames or four anchor points are available. Include local-language installation instructions and communit

Sample Testing for Emergency Mosquito Net Procurement

Run through these checks on the sample before signing off a bulk production run:

1. Dimension check: Measure length, width and height when hung. Confirm within ±5 cm (±2 in) of specification. Measure folded size to verify carton fit.
2. Weight check: Weigh the net on a digital scale. Confirm within ±10% of stated weight. Variation is normal for textile products.
3. Mesh count check: Count holes in a 1-inch square using a magnifying glass or mesh counter. Confirm 156 holes/inch² (±10%). Check for uneven weaving or thin spots.
4. Insecticide verification: Request the batch test report (HPLC or bioassay) confirming deltamethrin dosage (55 mg/m² ±25%). Confirm the lot number on the net matches the report.
5. Seam and loop check: Inspect all seams for skipped stitches or fraying. Pull each suspension loop firmly - the reinforcement must hold. Check the entry overlap closes without gaps.
6. Wash test (for LLIN): Perform one standard wash (ISO 6330, 30°C, mild detergent, line dry). Confirm no colour bleeding, mesh distortion or seam failure. Insecticide efficacy after 20 washes is verified by lab test, not visual inspection.
7. Packing check: Confirm the OPP bag, installation card, label language and carton marks match the specification. Verify the lot number is printed on both the net label and the carton.

 

Care and Storage for Mosquito Net Sourcing

Washing

LLINs can be hand-washed or machine-washed at 30°C (86°F) with mild detergent. Do not bleach, do not tumble dry, do not iron. Line dry in shade - direct sunlight accelerates insecticide degradation. Standard LLIN retains efficacy for at least 20 washes. Wash only when visibly dirty - over-washing shortens service life.
 

Installation

Hang the net so the bottom edge touches the mattress or floor (no gaps for mosquitoes to enter). For rectangular models, attach all four corner loops and pull taut. For conical models, hang from the single top loop and spread the bottom circumference around the bed. Tuck the lower edge under the mattress if possible. Keep the net away from open flames and sharp objects.
 

Storage

• Store unused nets in a cool, dry place away from direct sunlight and heat sources.
• Keep in original OPP packaging until distribution - this protects the insecticide from degradation.
• Do not store near pesticides, fuels or strong chemicals.
• Stock rotation: use oldest batch first. Insecticide efficacy declines gradually after 5 years even if unopened.

 

Repair and replacement

Small holes (under 2 cm) can be repaired with a fabric adhesive patch or needle and thread. Larger tears, broken loops, or mesh that has thinned with age should be replaced. A well-maintained LLIN in regular use lasts 3-5 years. Programme managers should plan replacement cycles accordingly and keep a 5% spare ratio for damaged nets during distribution.

Misconceptions About Mosquito Nets Wholesale

1. "All emergency mosquito nets are the same." No. LLINs are factory-treated with insecticide that lasts 3-5 years. Untreated nets provide only a physical barrier and offer no malaria protection if there is even a small gap. Conical and rectangular shapes serve different installation conditions.
2. "The finer the mesh, the better." Not always. 156 holes/inch² is the WHO standard - it blocks mosquitoes while allowing airflow. Meshes above 200 holes/inch² reduce ventilation and are uncomfortable in tropical heat. Finer meshes are only needed for sand fly or midge control.
3. "Insecticide-treated nets are dangerous for children." WHO-recommended LLINs (deltamethrin 55 mg/m²) are safe for children, pregnant women and everyday household use. The insecticide is bound into the fibre and releases at a controlled rate. Avoid touching the net immediately after it gets wet, and wash hands after handling a freshly unpacked net.
4. "LLINs cannot be washed." They can be washed up to 20 times with retained efficacy. Use cold water, mild detergent, and line dry in shade. Do not bleach or machine-wash on hot settings.
5. "Conical nets are better than rectangular ones." It depends on the site. Rectangular nets fit bed frames and give more sleeping space. Conical nets need only one suspension point and are easier for home installation. Choose based on available anchor points, not on shape alone.
6. "Self-supporting nets are too heavy for distribution." Model D weighs 900-1200 g - about twice a standard LLIN - but eliminates the need for hooks, cords, tools and installation labour. For sites with no suspension infrastructure, the total logistics cost is often lower.

 

Order Config for Emergency Mosquito Nets

Calculated using Model A (rectangular LLIN, deltamethrin, 190×180×150cm, 75D, 100 units/carton):

• Order quantity: 10,000 units, with a 5% spare buffer bringing the recommended total to 10,500 units
• Carton count: 105 cartons at 100 units per carton
• Carton dimensions: 60 × 40 × 40 cm each
• Cumulative volume: 105 × 0.096 m³ = roughly 10.1 m³
• Cumulative gross weight: 105 × 48 kg = roughly 5,040 kg
• Container share: A 40-foot high-cube container offers roughly 68 m³ of loading space. This 10,000-unit order occupies about 15% of one 40ft HQ container. A full 40ft HQ holds approximately 15,000-18,000 units of Model A.
• Label and traceability: Each carton marked with lot number, production date, insecticide batch, net count and destination project code. Each net carries a matching lot label.

 

Customisation and OEM Services for Mosquito Nets Bulk Orders

We support full OEM and customisation services for institutional bulk orders. Available customisations include Pantone colour matching, multilingual printed labels (English, French, Arabic, Spanish, Portuguese), donor or project logo printing on cartons and individual carry bags, specified insecticide type (deltamethrin or alpha-cypermethrin), mixed-size carton configuration, and batch-specific test reports. All customised nets still meet WHO physical specifications.






 

Customisation Workflow

1. Artwork confirmation (2-3 days): Buyer provides logo, label design, and carton mark specifications in AI or PDF vector format.
2. Pre-production sample (5-7 days): We produce 2-3 sample units with your custom labels, packaging, and configuration for approval.
3. Sample approval (buyer side): You review samples against tender requirements. Revisions are made until fully approved.
4. Mass production (15-45 days): Production begins after sample sign-off and 30% deposit. In-process QC reports shared at key milestones.
5. Final inspection and shipment (3-7 days): Pre-shipment inspection, batch test reports, container loading, and B/L release after balance payment.

 

Important Notes for Tender Customisation

• All customised nets still meet WHO physical specifications (156 mesh, 75D/100D yarn) - customisation applies to labelling, packaging, and accessories, not to core net quality.
• Insecticide changes require WHOPES-recommended active ingredients only; we cannot use unregistered insecticides for public health programmes.
• Custom artwork must be provided in AI or PDF vector format for accurate printing reproduction.
• For tenders requiring third-party inspection (SGS, BV, Intertek), we coordinate with your nominated inspector at our factory.

 

Lead Time for Mosquito Net Manufacturer

Standard Model A and Model B in white or blue ship within 7-15 working days. Custom colours, multi-language labels, or project-specific carton marks require 15-25 working days. Orders requiring third-party lab testing (HPLC dosage, bioassay) should budget an additional 10-15 working days. PBO-enhanced Model C is produced to order and requires 25-40 working days. Final delivery dates are confirmed in the contract once the sample and test requirements are approved.


For emergency response situations, standard LLIN stock can be dispatched within 72 hours of order confirmation, subject to available inventory. Available customisations cover: Pantone colour matching, custom label languages, donor/project logo printing on cartons and carry bags, specified insecticide type (deltamethrin or alpha-cypermethrin), mixed-size carton configuration, and batch-specific test reports. Lock in all custom requirements at quotation stage - mid-production changes can delay delivery.

 

Price and Cost Analysis for African LLIN Procurement

Understanding pricing for mosquito nets bulk orders helps African buyers budget accurately for government tenders and stockpile procurement. LLIN prices typically range from $1.20 to $3.50 per net depending on specifications, insecticide type, and order volume. Larger orders of 50,000+ units from a reliable mosquito net manufacturer can reduce unit costs by 20-30% compared to small trial orders.


Key cost factors for mosquito nets wholesale tenders:

• Insecticide type: Deltamethrin is standard; PBO combination nets cost 15-25% more
• Mesh count: 156 holes/inch² is standard for Africa; 180 holes/inch² adds cost
• Size: Single bed (180×160×150cm) vs family size affects material usage
• Packing: Individual polybag + carton vs bulk packing changes logistics cost
• Order volume: 10,000 units vs 100,000 units has significant per-unit difference
• Documentation: Tender documentation, bid bonds, and compliance certificates add administrative cost

Example budget for 100,000 rectangular LLINs under government tender: Product cost approximately $150,000-$220,000; ocean freight to major African ports $8,000-$15,000; insurance and documentation $2,000-$4,000; bid bond and performance bond typically 2-5% of contract value. Total landed cost typically $1.60-$2.40 per net. Payment is commonly arranged via T/T telegraphic transfer with 30% deposit and 70% balance before shipment, which is the standard arrangement most LLIN supplier factories accept for emergency mosquito nets orders.

 

Government Tender and Stockpile Procurement Pathways

African mosquito net procurement for government tenders and national stockpiles follows several distinct pathways. Understanding the tender documentation requirements and bid evaluation criteria helps suppliers compete effectively for mosquito nets bulk contracts.


Pathway 1: National government tender - African ministries of health publish tender notices through national procurement authorities or global fund grants. Tender documents typically require technical specifications, company registration, manufacturing capacity proof, test reports, and financial references. Bid evaluation usually combines technical score (60-70%) and price score (30-40%). Successful bidders enter framework agreements for 1-3 year supply contracts to national stockpiles.


Pathway 2: UN direct procurement (UNICEF, UNHCR, WHO) - Large tenders published on UNGM (UN Global Marketplace). These typically require pre-qualified supplier status and competitive bidding. Annual LLIN procurement through UN agencies exceeds 200 million nets globally, with sub-Saharan Africa receiving the majority. Tender packages include detailed technical specifications, delivery schedules to multiple destinations, and strict compliance documentation requirements.


Pathway 3: Government stockpile replenishment - Many African countries maintain national emergency stockpiles of LLINs for disaster response and outbreak control. Stockpile procurement often uses simplified tender procedures or direct negotiation with pre-approved suppliers. Requirements include guaranteed delivery within 30-45 days, storage-ready packaging, and batch traceability for stock rotation management. This pathway is well-suited to emergency mosquito net procurement where speed is critical.


Pathway 4: NGO and humanitarian procurement - International NGOs and local organizations procure directly from manufacturers or through intermediaries. Tender requirements are often more flexible; many accept WHO-specification products with valid test reports. Purchase orders are typically smaller than government tenders but more frequent, making this a valuable channel for mosquito nets wholesale suppliers building African market presence.



 

WHO Standards and Insecticide Treatment for Tender Compliance

For African government tenders and stockpile contracts, LLIN products must meet WHO specifications for insecticide content, mesh durability, and wash resistance. Tender evaluation committees verify compliance through test reports and batch documentation. The WHO Pesticide Evaluation Scheme (WHOPES) recommends specific insecticides for mosquito nets bulk production, and products using these recommended active ingredients are widely accepted in tender technical evaluations.


WHOPES-recommended insecticides for tender-compliant LLINs:

• Deltamethrin - The most widely used pyrethroid, standard for most African tenders. Typical target dosage 55 mg/m² (or 1.8 g/kg for 100D polyester)
• Permethrin - Used in some regional tenders; effective but slightly less durable after repeated washing
• PBO (Piperonyl Butoxide) combination - Recommended for tenders in pyrethroid-resistance zones, particularly West and Central Africa
• Chlorfenapyr combination - Newer generation nets accepted in tenders targeting high-resistance areas

Tender documentation checklist for WHO compliance: Mesh count minimum 156 holes/inch² (some tenders require 180); fabric weight typically 100D polyester; insecticide retention after 20 standard washes; tensile strength and tear resistance test reports; batch traceability records; certificate of origin; and manufacturer declaration of conformity. A credible mosquito net manufacturer should provide all these documents as part of the tender submission for mosquito nets wholesale contracts.


Important note on certification for tenders: WHOPES full certification is required for some large UN tenders. For many national government tenders and stockpile contracts, products manufactured to WHO specifications using WHOPES-recommended insecticides, supported by valid third-party test reports, are accepted. Suppliers should carefully review each tender document to confirm specific certification requirements before submitting bids.

Africa is not a single tender market for emergency mosquito nets. Regional differences in malaria transmission, insecticide resistance, tender systems, and stockpile management mean that product specifications and bid requirements vary significantly across the continent.


East Africa (Kenya, Tanzania, Uganda, Ethiopia): Well-established national tender systems with annual or biennial procurement cycles. Deltamethrin LLINs are standard; some tenders now specify PBO nets due to resistance. Government stockpiles are managed by national malaria control programs with defined reorder thresholds. Tender evaluation emphasizes local distribution capacity and after-sales support.


West Africa (Nigeria, Ghana, Senegal, Mali): Largest tender volumes globally. Pyrethroid resistance means PBO nets are increasingly specified in tender documents. Nigeria uses both federal-level tenders and state-level procurement. Stockpile management is decentralized, with emergency reserves maintained at state and national levels. Price competitiveness is the primary evaluation criterion in many tenders.


Southern Africa (Mozambique, Zambia, Malawi): Tender cycles align with mass distribution campaigns every 3-4 years. Government stockpiles serve as buffer between campaign cycles. Deltamethrin remains effective in most areas; resistance monitoring is ongoing. Tenders often require delivery to multiple provincial warehouses, adding logistics complexity to mosquito net sourcing.


Central Africa (DRC, Cameroon, Chad): Tender systems are less centralized; emergency and NGO procurement complement government tenders. Stockpile management is challenging due to logistics constraints. Tenders prioritize durability and ease of distribution. Delivery to inland destinations can add significant cost and time, requiring careful planning in tender pricing.

 

Common Tender Pitfalls and Stockpile Management Issues

African LLIN procurement tenders and stockpile management encounter several recurring problems. Awareness of these pitfalls helps suppliers prepare competitive bids and helps buyers avoid costly mistakes in mosquito nets bulk procurement.


Pitfall 1: Incomplete tender documentation. Missing test reports, certificates of origin, or company registration documents leads to automatic disqualification in technical evaluation. Always cross-check tender requirements against a documentation checklist before submission. Late submissions are typically rejected without exception.


Pitfall 2: Misrepresented certification status in bids. Some suppliers claim WHOPES certification in tender documents without holding it. Tender evaluators verify certification directly through WHO databases. For products without full certification, clearly state "manufactured to WHO specifications using WHOPES-recommended insecticides" and provide test reports as supporting evidence.


Pitfall 3: Insecticide content below tender specification. Cost-cutting manufacturers may apply less insecticide than specified in tender documents. Batch-specific test reports from accredited laboratories are required for compliance. Tender contracts often include penalty clauses for non-conforming batches, including rejection and replacement at supplier cost.


Pitfall 4: Inadequate packaging for stockpile storage. Government stockpiles may store nets for 12-24 months before distribution. Insufficient carton strength or lack of moisture protection leads to damage and insecticide degradation during storage. Tender specifications typically require double-wall cartons, individual polybags, and moisture-proof packaging.


Pitfall 5: Ignoring resistance patterns in target region. Tenders in high-resistance areas now specify PBO or combination nets. Bidding standard deltamethrin-only nets for these regions results in technical non-compliance. Always consult WHO resistance maps and tender specifications before determining the product offering.


Pitfall 6: Unrealistic delivery schedules in tender bids. LLIN production requires 25-40 days plus 25-35 days ocean freight. Tender contracts include liquidated damages for late delivery (typically 0.5% per week, capped at 10% of contract value). Some LLIN supplier factories maintain stock of standard models for emergency stockpile dispatch, which can be a competitive advantage in emergency mosquito nets tenders with short delivery windows.

Factory Audit Checklist for Pre-Qualification

• Production capability: In-house weaving or reliable yarn supply? Sewing line capacity? Automated insecticide treatment line?
• Quality control: Is there an in-house lab? Can they run HPLC, cone bioassay, and wash resistance tests? Are QC records maintained?
• Raw material control: Do they inspect incoming yarn and insecticide? Can they provide supplier certificates?
• Compliance documentation: ISO 9001 quality system? Test reports from third-party labs? WHO specification compliance statements?
• Export experience: Have they shipped to African markets? Do they understand tender documentation requirements (CO, Form A, inspection certificates)?
• Ethical production: No child labour? Fair wages? Safe working conditions? (Important for NGO and UN procurement)
• Sample evaluation: Always request 2-3 physical samples before ordering. Verify mesh count, denier, dimensions, and label accuracy yourself.

Frequently Asked Questions

What is an LLIN and how is it different from a normal mosquito net?

LLIN stands for Long-Lasting Insecticidal Net. It is factory-treated with pyrethroid insecticide that lasts 3-5 years and at least 20 washes, unlike ordinary nets which require regular re-treatment. For mosquito nets bulk procurement in malaria-endemic African regions, LLINs are the WHO-recommended standard for government tenders and national stockpiles.
 

What mesh count do you use and why?

Our standard LLIN uses 156 holes per square inch (approximately 24 holes per cm²), the WHO-recommended density. This blocks mosquitoes while allowing sufficient airflow in tropical climates. Finer 180+ hole meshes are available on request for tenders specifying higher density. All models from our mosquito net manufacturer meet ISO bursting strength standards.
 

What insecticide is used and is it safe?

Standard LLIN uses deltamethrin at 55 mg/m², a WHO-recommended and WHOPES-listed pyrethroid. It is safe for children, pregnant women and everyday use. The insecticide is bound into the fibre and releases at a controlled rate. PBO-enhanced models (Model C) are available for pyrethroid-resistance zones, a common requirement in West African LLIN procurement tenders
 

How many washes does an LLIN survive?

Our LLIN retains insecticidal efficacy for at least 20 standard washes (ISO 6330, 30°C, mild detergent, line dry). Service life is 3-5 years under normal use. Tender contracts typically require wash-resistance test reports as part of compliance documentation for mosquito nets wholesale supply to government stockpiles.
 

What size should I order for a refugee camp or shelter?

For double-bed use (covers 2 people), the standard is 190 × 180 × 150 cm (Model A rectangular), aligning with Sphere Handbook standards of one net per two people. For single beds, Model B conical (1050 cm bottom circumference) works where only one ceiling anchor is available. Confirm bed dimensions and suspension points with your LLIN supplier before finalizing tender quantities.
 

What if our shelter has no hooks or beams to hang a net?

Use Model D - the self-supporting frame net with a built-in flexible steel frame that pops open without tools. Ideal for school gyms, warehouses, tent shelters and other sites with no suspension infrastructure. This model is frequently specified in emergency emergency mosquito nets tenders for rapid deployment scenarios.
 

Can you provide WHO PQ or third-party test reports?

Third-party test reports (HPLC insecticide dosage verification, bioassay, wash resistance, tensile strength) can be organized per batch from accredited laboratories. While we manufacture to WHO specifications using WHOPES-recommended insecticides, full WHO PQ certification status should be confirmed at tender stage. Test reports are standard compliance documents for African government mosquito net procurement.
 

How many mosquito nets fit in a shipping container?

For Model A (100 units/carton, 60×40×40cm), a 40-foot high-cube container holds approximately 15,000-18,000 units. Model B (80 units/carton) holds ~12,000-14,000. Container loading plans are provided with every quotation, an important consideration for stockpile mosquito nets bulk logistics planning.
 

Can labels be printed in our local language?

Yes. We support English, French, Spanish, Arabic, Portuguese and other languages on request. Custom project logos, donor acknowledgment text and carton shipping marks can be configured to match tender requirements. Multilingual labels are essential for community distribution programs across African mosquito nets wholesale markets.
 

What is the difference between rectangular and conical nets?

Rectangular nets (Model A) attach at four corners and provide more sleeping space - ideal for bed frames in camps and fixed shelters. Conical nets (Model B) hang from a single point and are easier for home installation where only one ceiling anchor exists. Both are available with deltamethrin treatment for LLIN procurement contracts.
 

What is PBO and when do we need it?

PBO (Piperonyl Butoxide) is a synergist added to the roof panel of Model C. It blocks mosquito detoxification enzymes, restoring efficacy of deltamethrin in pyrethroid-resistance zones. PBO nets cost 15-25% more but are increasingly specified in tenders for West and Central Africa where resistance is widespread. Consult WHO resistance maps before determining product specifications for emergency mosquito net procurement.
 

How do we verify the insecticide dosage on delivery?

Each batch carries a lot number linked to a test report. You can request HPLC analysis certificates confirming deltamethrin dosage (55 mg/m² ±25%) and bioassay results. Pre-shipment inspection is recommended for large government tender orders. Batch traceability is a standard audit requirement for donor-funded mosquito nets wholesale programs.
 

Can nets be supplied untreated for institutions that treat them themselves?

Yes. Models D and E are standard untreated, and Model A can be supplied untreated on request. Untreated nets are suitable for non-malaria regions or institutions with in-house treatment capacity. Confirm treatment requirements in your tender specification - this affects pricing and lead time from your mosquito net manufacturer.
