After the immature mosquitoes (larvae) and larval insects are located in their water habitats, crews work to suppress their ability to become adults. We use bio-chemical sprays containing bacteria or insect growth regulating hormones to address the larvae. These sprays, while being very effective controls for immature mosquitoes, have little impact on the surrounding environment. If the location is suitable, Mosquito Control Services will transport mosquito fish to the breeding site and let nature take over. The fish then feed on mosquito larvae, providing a natural biological solution to the problem. Mosquito Control Services provides these mosquito fish to homeowners in our contracted areas, free of charge, for use in private ponds, fountains, and ornamental pools.
