Mosquitoes thrive in warm weather and need stagnant water to lay eggs. Just a few ounces of water—left in a plant saucer, birdbath, or clogged gutter—can hatch hundreds of mosquitoes in days. Arizona’s summer monsoon season increases mosquito populations, especially in backyards with poor drainage or standing water.

Mosquito bites cause itchy welts, and some species in Arizona can carry West Nile virus or other mosquito-borne diseases. Their buzzing presence and bites can make outdoor spaces miserable if not managed.
