❓ Delaware Pest Control FAQ

When is the best time of year to get pest control treatment in Delaware?

Does homeowners insurance cover pest damage?
Standard homeowners insurance policies explicitly exclude pest damage, classifying it as a maintenance issue.

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 Delaware Department of Agriculture 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.
