Aerial Mosquito Larvicides Applications

chd_wnv_helicopter_124x124

To better protect our communities and the environment, the Vector Control Program (VCP) applies mosquito larvicide via helicopter to mosquito breeding areas that cannot be treated by hand.  These aerial applications occur every three to four weeks during the mosquito breeding season, generally April to October, or as needed.

The granular larvicide used by the Vector Control Program act specifically on mosquito larvae and will not harm people, pets, plants, or wildlife. The larvicide consists of granules containing Bacillus sphaericus and Bacillus thuringiensis israelensis.  These naturally occuring bacteria target mosquito larvae and prevent them from developing into biting adults.
