The invention relates to an insecticide composition for application to a fabric material, typically a fabric material that forms a mosquito net. The composition includes an insecticide and a copolymeric binder that permits application of the insecticide to a fabric material and hence imparts hydrophobicity to the insecticide. The composition includes also a dispersing agent that, after application of the composition to a fabric material and upon wetting of the material, reduces the hydrophobicity imparted to the insecticide by the copolymeric binder and hence permits controlled, limited insecticide release. Insecticide release thus occurs only in limited quantities at intervals, particularly in response to the fabric material being exposed to wetting, such as when it is washed. Insecticide is thus rendered bioavailable for killing insects after multiple washes. |
