Although extract of the neem tree is used in some agricultural insecticides, it is almost an urban legend that if you plant it around your house, it will keep mosquitoes away. I planted neem around my thatched hut in Azua, mostly because its the only species that would grow tall enough to provide some shade and also, it thrives in very low moisture soil (arid regions), however, Ive noticed that my mosquito population has ramained about the same, before and after the neem. Neem was brought into the country immediately after Hurricane David devastated the country in 1979, as a reforestation species. I've learned recently that neem is not recommended for planting in low-rainfall regions, since it does not produce enough moisture to protect the earth from the heat, or enough humidity/coolness to attract rainfall. In fact, it could worsen the overall aridity of the soil.
