There are about 60 different species of mosquitoes in Pennsylvania. While most do not transmit West Nile virus, several mosquito species have been found to transmit the virus. Mosquitoes lay their eggs in stagnant water around the home. Weeds, tall grass, shrubbery and discarded tires also provide an outdoor home for adult mosquitoes. By eliminating places for mosquitoes to breed, we can go a long way to prevent West Nile virus.
Mosquitoes breed in standing water.
Even a small bucket that has stagnant water in it for seven days can become home to up to 1,000 mosquitoes. Do not overlook containers that have become overgrown by aquatic vegetation. Pay special attention to discarded tires that may have accumulated on your property. Drill holes in the bottom of recycling containers that are left out of doors. Drainage holes that are located on the container sides collect enough water for mosquitoes to breed in.
