Prune Hedges and Mow the Yard
Hedges, bushes and tall grass provide shade that shelters mosquitoes. They need a place to get out of the heat and sun during the day, so the fewer shaded areas they find, the less they’ll congregate in your yard.
Keep the hedges and bushes trimmed, and mow the yard at least once a week. Mow or till weedy spots to minimize shade and to keep these marginal areas from becoming overgrown jungles. Encourage your neighbors to do the same. Otherwise, you’ll just drive the mosquitoes next door—and they’ll come back often to visit.
