PermaNet 2.0: A long-lasting insecticidal net (LLIN) composed of knitted poly-filament polyester fibers and infused with deltamethrin to knockdown and kill mosquitos that come in contact with it.
Distributors / Implementing Organizations
Vestergaard Frandsen works with local partners in country to deliver products to end users.
Intellectural Property Type
User Provision Model
Vestergaard Frandsen has developed a distribution network across Africa with the help of local partners that helps deliver the product through direct sales.
Distributions to Date Status
Millions are distributed each year.
Bursting Strength (kPa)
Expected lifespan (months, washes)
Insecticide content (g/kg)
1.4 – 1.8 + 25%
Protection from insect entry (yes/no)
Retreatment required? (frequency)
The net is made from knitted poly-filament polyester fibers.
After a certain period of use, Vestergaard Frandsen Hanoi laboratories offers testing to ensure proper functionality of the nets.
Holes can be patched with local materials, although the insecticide will no longer be present on that spot.
Lifetime largely depends on usage.
Manufacturer Specified Performance Parameters
- Less than 5% shrinkage/expansion in both dimensions
- Rapidly regains insecticidal efficacy after washing
Vetted Performance Status
Report of the Twelfth WHOPES Working Group Meeting: More than 90% of nets tested at each time-point met the WHOPES criteria for the cone test, except for nets collected at 24 months post-distribution, when only 71% of nets met the WHOPES criteria for the cone test.
- 1.4 g/kg deltamethrin concentration for 100-denier net
- 1.8 g/kg deltamethrin concentration for 75-denier net
- 41.5% retention of deltamethrin concentration after 36 months
