The ZeroFly® shelter has several different built in UV filters. Some of these filters protect the plastic material and the others protect the insecticide. The UV filters that protect the insecticide even have the ability to follow the insecticide, while it is immigrating to the surface. The insecticide on the surface will slowly degrade from the external exposure, mainly sunlight. The built in UV filters will slow down this process, but will not be able to stop it. In order to compensate for the loss of insecticide on the surface, the ZeroFly® shelter has a depot of insecticide in the central layer. The insecticide from the central depot will migrate towards the surface.

ZeroFly® is right now undergoing WHOPES phase 3 in Sierra Leone. The test is made under supervision by Mentor Europe in cooperation with Johns Hopkins University. Results of phase 2 were published on June 22, 2002.

The insecticide used in ZeroFly® is Deltamethrin. Deltamethrin has undergone WHOPES evaluation.

ZeroFly® is an insecticide incorporated plastic sheeting for malaria prevention in complex emergencies.

Plastic sheeting is among the first aid articles to be distributed to refugees in emergency situations. To equip these plastic sheetings with disease control abilities, is therefore potentially a highly efficient health improvement tool. The ZeroFly® shelter contains insecticide and has, in laboratory as well as field trials, been proven effective against disease vectors such as malaria mosquitoes.
