The Best Time of Year to Treat for Mosquitos

March 26, 2025

When it comes to mosquitoes, timing is everything. These buzzing pests are more than just annoying—they can carry diseases like West Nile virus and Eastern Equine Encephalitis (EEE). If you want to enjoy your yard without constantly swatting or worrying about bites, it’s important to know the best time of year to treat for mosquitoes.

At ProSource Pest Solutions, we help homeowners in Southington and surrounding areas stay ahead of mosquito season with timely, effective treatments. Here’s what you need to know.

When Do Mosquitoes Become Active in Connecticut?

Mosquitoes typically start showing up in Connecticut once temperatures consistently hit 50°F, which usually happens in late April or early May. From there, mosquito activity ramps up quickly—especially after spring rain creates standing water, where mosquitoes love to breed.

Peak Mosquito Season

Connecticut’s mosquito season typically peaks between June and September, when the weather is warm and humid. If you're outdoors during these months, chances are you’ve already dealt with bites or seen mosquitoes hovering around shady areas of your yard.

Waiting until summer to treat your yard might feel like the right time—but by then, mosquito populations are already established and harder to control.

The Best Time to Start Treatments

The ideal time to start mosquito treatments is early spring, just before mosquito activity kicks into high gear. This helps stop the breeding cycle before it starts and keeps the population under control all season long.

At ProSource Pest Solutions, we recommend starting treatments in April or early May, with follow-up visits every few weeks through the summer and into early fall. These treatments target mosquito resting and breeding areas and help create a protective barrier around your home.

Why Consistency Matters

One treatment won’t keep mosquitoes away for good. That’s why our seasonal mosquito control plans are designed for long-term prevention. Consistent treatments reduce breeding, eliminate adult mosquitoes, and keep your yard safer for your family and pets.
