❓ Connecticut Pest Control FAQ

When is the best time of year to get pest control treatment in Connecticut?
Early spring (February–April) is the highest-impact time for preventive treatment in Connecticut — before colonies establish and before overwintering pests become active. A perimeter treatment in March or April creates a barrier that dramatically reduces summer pest pressure.
What pests are unique to Connecticut compared to other states?
Connecticut's humid continental climate creates specific pest pressure patterns. Check with your local cooperative extension service for the most current data on invasive species and emerging pest threats in your specific county.
Does homeowners insurance cover pest damage?
Standard homeowners insurance policies explicitly exclude pest damage, classifying it as a maintenance issue. Termite damage in particular — often totaling tens of thousands of dollars — is almost never covered. Standalone termite warranties from licensed pest control companies are the primary protection available.
How do I find a reputable pest control company?
Verify the company holds a current Connecticut Dept. of Energy & Environmental Protection license. Check Google and Yelp reviews from the past 12 months. Look for NPMA (National Pest Management Association) membership. Always get at least two in-home quotes before committing.
