Here are some steps we as a community can take to lessen mosquitoes’ sting. Mosquitoes breed in standing water. Eliminate the breeding ground to have a direct impact on reducing local mosquito populations. This approach is more effective than fogging/spraying. Fogging only kills adult mosquitoes. It has no effect on larvae, which can hatch and breed a whole new generation of mosquitoes shortly after spraying. Fogging also kills butterflies, pollinators and other beneficial insects, some of which may actually eat mosquitoes.
