Intervention classes with PQ listings for vector control

Bed nets

Bed nets are a physical barrier that can be used to protect individuals from mosquito bites and are particularly useful for targeting species which are active while people sleep. Insecticide-treated bed nets (ITNs) are considered a highly effective tool for mosquito control and are typically treated with pyrethroids, with novel nets now containing a secondary chemical such as chlorfenapyr or piperonyl butoxide (PBO).

Indoor residual spraying

Indoor residual spraying (IRS) is a method of mosquito control that involves applying insecticide to the interior surfaces of houses, buildings, and other structures where mosquitoes are likely to rest. IRS is typically implemented as part of broader mosquito control programmes that may also include the use of insecticide-treated bed nets, larval control and/or community education.

Larvicides are used to control mosquito populations by targeting the immature stages, specifically the larvae and pupae. They are typically applied directly to breeding sites, such as standing water and man-made containers. Larvicides work by disrupting the developmental process of the mosquito larvae, causing death, or preventing them from maturing through to the adult stage.

Space sprays

Space sprays are a vector control method that involves the use of insecticides that are dispersed in the air as a fine mist or aerosol. Insecticide droplets remain suspended in the air for a certain length of time, killing mosquitoes that come into contact with them. Space sprays are often used in outdoor areas such as parks, sports fields, and other public spaces.
