About Grinnage Exterminating

Grinnage Exterminating was built around a simple idea: Delaware homeowners deserve an exterminator who knows their street, not a national brand routing calls through another state. We live and work here, so we already know what the pest pressure looks like in a Newark student rental, a Wilmington row home, a Middletown new build and a Rehoboth rental cottage.

That local knowledge changes the work. We know termite swarms hit in March, that mice start testing foundations the first cold week of October, and that yellow jacket colonies peak right when the backyard gets the most use. Instead of a generic spray schedule, you get treatment timed to what's actually happening in Delaware that month.

Every job starts with a free inspection and a flat-rate quote in writing. We tell you what we found, what it takes to fix it, and what you can do yourself for free - even when that means a smaller invoice for us. That's how you earn a customer for the next decade instead of the next visit.
