You can reduce the number of mosquitoes around your home and neighborhood by reducing the amount of standing water available for mosquito breeding. Pay special attention to discarded tires. Stagnant water in used tires is where most mosquitoes breed. Drill holes in the bottom of recycling containers left outdoors. Have clogged roof gutters cleaned every year, particularly if the leaves from surrounding trees have a tendency to plug up the drains.
Roof gutters can produce millions of mosquitoes each season.
Turn over plastic wading pools when not in use. Stagnant water in a wading pool becomes a place for mosquitoes to breed. Turn over wheelbarrows and don't let water stagnate in birdbaths. Both provide breeding habitats for domestic mosquitoes. Aerate ornamental pools or stock them with fish.
