General Questions

What is PermaNet® Screen?

PermaNet® Screen is the first and only long-lasting insecticidal screen for outdoor mosquito control that kills mosquitoes by contact. This advanced new solution provides long-lasting insecticidal efficacy for at least two years, without the need to retreat.

How does PermaNet® Screen work?

PermaNet® Screen is made from polyethylene treated with deltamethrin, a World Health Organization approved insecticide. Using a patented insecticidal release technology, the insecticide migrates from inside the screen fabric to the surface and continuously regenerates to the surface for at least two years. Mosquitoes die when they come into contact with the insecticide on the surface of the screen.

Can PermaNet® Screen be used outside of the house to protect against mosquitoes?

Yes, PermaNet® Screen can be used to kill mosquitoes and reduce the mosquito population when applied to outdoor areas including schools, health facilities, open-air dining and shopping venues, and outdoor recreation facilities.

How long will PermaNet® Screen last?

PermaNet® Screen is designed for outdoor use. The insecticide is UV protected and kills mosquitoes for at least 24 months, even with repeated exposure to sunlight.

Does PermaNet® Screen kill all species of mosquitoes?

PermaNet® Screen has been fully tested and effectively kills Anopheles, Aedes and Culex mosquitoes by contact (EPA Reg No.: 85787-1; EPA Est No.: 92645-VNM-1).

How long does it take for mosquitoes to die once they contact PermaNet® Screen?

The length of time it takes for a mosquito to die after coming into contact with PermaNet® Screen varies, but can be as fast as a few seconds. The longer a mosquito spends on the PermaNet® Screen, the more insecticide they are exposed to and the more quickly they will die. Deltamethrin is a fast-acting insecticide that ‘knocks down’ mosquitoes within 60 minutes of exposure, and usually kills within 24 hours.

What other insects does PermaNet® Screen kill?

PermaNet® Screen also kills stable flies and midges (no-see-ums).

Who is the manufacturer?

PermaNet® Screen is manufactured by Vestergaard, a global health company committed to developing innovative technologies that play a significant role in fighting malaria and other vector-borne diseases, diarrheal diseases and neglected tropical diseases. In fact, more than 1.5 billion people have benefitted from our PemaNet® long-lasting insecticidal bed nets since 2003.

Safety And Efficacy

Is PermaNet® Screen safe for use around children and pets?

The insecticide used in PermaNet® Screen is the same that is used in mosquito nets approved by the World Health Organization to protect people, including newborn babies from malaria. Only a small fraction of the insecticide is on the surface of the screen; the rest is locked away inside as a "reservoir" inside the fibers.

Avoid using Permanent Screen around cats which are sensitive to deltamethrin and other pyrethroid insecticides. Cats (unlike dogs) do not have the enzyme responsible for metabolizing or breaking down pyrethroids.

What studies have been done to confirm efficacy of PermaNet® Screen?

PermaNet® Screen has been tested in both laboratory and field settings. It kills mosquitoes by contact, including Aedes (mosquitoes that can transmit Zika, Dengue, Chikungunya, Yellow Fever), Culex (mosquitoes that transmit the West Nile virus) and Anopheles (mosquitoes that transmit malaria), as well as biting midges (Culicoides). No decline in efficacy was observed with PermaNet® Screen that had aged outdoors for 27 months, with 100 percent mortality recorded with Aedes aeqypti and Anopheles gambiae after only three minutes of exposure.

What studies have been done to demonstrate the safety of PermaNet® Screen?

Safety and toxicity studies following OECD (Organization for Economic Co-operation and Development) guidelines have been completed (EPA Reg No.: 85787-1; EPA Est No.: 92645-VNM-1). The insecticide used in PermaNet® Screen has a low mammalian toxicity and is approved by the World Health Organization for use in bed nets, which are used to protect newborns and young children from mosquitoes.

My hands got itchy when installing PermaNet® Screen. What does that mean?

Wear waterproof, rubber or non-permeable protective gloves when handling the PermaNet® Screen. The insecticide in PermaNet® Screen can give some irritation to certain people. If you feel any irritation after handling the screen without gloves, wash your hands with plenty of soapy water.

Will it still work after 24 months?

PermaNet® Screen effectively kills mosquitoes for at least 24 months. After this time, there may be some reduction in efficacy (it may take longer to kill mosquitoes or it won’t kill 100% of mosquitoes that contact the PermaNet® Screen) but the efficacy does not disappear completely. It reduces gradually as the insecticide inside the fibers become depleted.

How do I clean PermaNet® Screen?
