Tick & Mosquito Season in Connecticut: What Treatment Covers and What It Costs

ProSource Pest Solutions • June 8, 2026

In Connecticut, ticks and mosquitoes are more than a backyard nuisance, they're a seasonal health concern. Knowing when the season runs, what a professional treatment actually covers, and what it costs helps you protect your family and budget with confidence. Here's a clear breakdown.

Tick & Mosquito Season in Connecticut: What Treatment Covers and What It Costs

Connecticut's tick and mosquito season generally runs April through October. Ticks can transmit Lyme disease, while mosquitoes are associated with West Nile virus and Eastern Equine Encephalitis (EEE). A consistent seasonal program keeps activity low during the months your yard sees the most use.

When the Season Starts and Peaks

Activity begins in early spring as temperatures rise, builds through the warm summer months, and tapers off in fall. Starting treatment early in the season is more effective than waiting until pests are already swarming, because it reduces the breeding population before it multiplies.

What a Tick & Mosquito Treatment Covers

ProSource does not simply spray your open lawn, because that's not where ticks and mosquitoes live. Treatment targets the areas where they actually breed and rest: the property perimeter, mulch beds, shrubs, tree lines, and the shaded wooded transition zones along the edges of your yard.

Rain Re-Treatment Is Included

If heavy rain follows shortly after a visit, re-treatment is included at no extra charge. Each monthly visit during the season maintains coverage so protection stays consistent from spring through fall.

What Tick & Mosquito Treatment Costs

Pricing is based on the size of your property. For most Connecticut homes, monthly seasonal pricing starts at $125 per month for properties between a half-acre and one acre, and $150 per month for properties between one and two acres.

Larger or Heavily Wooded Properties

Larger lots, or properties with extensive wooded areas, are quoted individually. Because coverage depends on how much treatable edge and brush your property has, the most accurate price comes from a free on-site inspection rather than a phone estimate.

Local, Licensed, and Guaranteed

Founded in 2018 by industry veteran John Rosario, ProSource serves homeowners within roughly 15 miles of Waterbury, including Southington and surrounding towns. Read more about what to expect during tick and mosquito season or how acreage affects pricing.

Frequently Asked Questions

  • When does tick and mosquito season start in Connecticut?

    Tick and mosquito season in Connecticut generally runs from April through October. Activity begins in early spring, peaks during the warm summer months, and tapers off in the fall. Starting treatment early in the season is more effective than waiting, because it lowers the breeding population before pests multiply and spread across your yard.

  • How much does tick and mosquito treatment cost in CT?

    Monthly seasonal pricing starts at $125 per month for properties between a half-acre and one acre, and $150 per month for properties between one and two acres. Larger or heavily wooded lots are quoted individually based on how much treatable area they have. A free on-site inspection provides the most accurate price for your specific property.

  • What happens if it rains after my treatment?

    If heavy rain follows shortly after your visit, re-treatment is included at no extra charge. ProSource builds rain coverage into the seasonal program so your protection stays consistent throughout the spring, summer, and fall months. You don't need to worry about a single storm undoing the work you paid for.

  • Why not just spray the whole lawn?

    Spraying open lawn does little because ticks and mosquitoes don't live there. Ticks shelter in leaf litter, brush, and shaded tree lines, while mosquitoes rest in cool, damp, vegetated areas. Targeting those perimeter and transition zones controls the population far more effectively than blanket-treating grass where the pests rarely spend time.
