Sprinklers themselves don’t attract pests. But overwatering leaves standing water and that is where mosquitoes breed.
You've wondered whether running the sprinklers is feeding your mosquito problem. The answer is no, at least in the strict sense. The water itself doesn't lure them in, but when it is left standing for a long time after the sprinklers are done running, it can.
Mosquitoes require very little standing water to lay their eggs, often using a volume as small as a bottle cap. When sprinklers overwater your yard, they create the perfect damp spots and small pools for larvae to develop. This excess water typically collects in low-lying depressions, plant saucers, folds in tarps, children's toys, and clogged drains. Once mosquitoes find places to breed, more adults hatch, and then that kicks off another breeding cycle. It can escalate quickly.
Ultimately, this happens when overwatering. When sprinklers are set to a heavy schedule, or there are leaks or broken heads, parts of the yard can be left wet all the time. That is begging for mosquitoes.
Still, you probably don’t want to give up the sprinklers. If that’s the case, try watering in the morning so the lawn and beds dry throughout the day. Also smart is to water less often but more deeply. And if you spot leaks, fix them. Beyond that, make sure you don’t have any containers that are catching runoff like saucers, buckets, toys, or tarps.
If you're tired of your own sprinklers seeming to feed the mosquitoes, Mosquito Squad of Bergen and Passaic County can help. Mosquito Squad treats the resting areas where adult mosquitoes shelter and helps you target the breeding sources. This helps you protect your yard with up to 90% reduction in mosquito activity on a recurring 21-day cycle.
