Eave tubes are 6-inch diameter plastic pipes that are fitted in walls underneath the roof of houses. Mosquitoes are attracted into them when responding to the body odour of house occupants. House entry is prevented by netting fitted inside the tube that is treated with coating that binds powder particles of insecticides. The novel netting has permitted the use of mosquito control insecticides in powder formulations; a fairly noble break through which will help restore effective shelf life of conventional insecticides (Andriessen et al. PNAS 2015).
