Durham Pest Control You Can Trust
Protecting Your Home & Family

Submit the form and your free inspection is booked in approximately 2 hours. For urgent infestations we do our best to offer same-day service in the Durham area when the request comes in before noon; otherwise your inspection is scheduled within 24–48 hours, including evening slots.

Cost depends on the pest, your home's size, and the severity — which is exactly why our on-site inspection is free. We provide a personalized flat-fee quote based on your specific situation before any work begins, with no hidden charges and zero obligation to proceed. Call (919) 606-8686 for your free inspection.

Absolutely. If pests return between scheduled visits on any of our recurring plans, we come back and re-treat at no charge. We're family-owned in Durham — your satisfaction is the only thing that matters to us. See our Terms of Service for full guarantee details.

For most general pest treatments — no. You can stay in the home; we'll just ask you to keep pets out of treated rooms until products dry (usually 30–60 minutes). For specialty treatments like bed bug heat treatment — a separate program, not part of the quarterly plan — we'll give you specific instructions in advance.

We're biased, but here's the honest answer: the best pest control company for you is one that's locally owned (not a national franchise reading from a script), state-licensed, and willing to guarantee the work in writing. Castle Exterminators has been family-owned in Durham since 2011, is licensed in North Carolina (NC Structural Pest Control License #1979PW), holds a 5.0★ average rating on Google, and re-treats between visits at no charge. Get a few quotes, ask about their license number, and pick the crew you'd actually trust in your home.

For most Durham-area homes, quarterly (every 90 days) is the sweet spot. NC's humid climate keeps pests active nearly year-round — spring brings ants and termite swarmers, summer brings mosquitoes and wasps, fall brings rodents seeking shelter, and winter is prime time for German roach populations to build indoors. A quarterly visit refreshes the exterior barrier and catches new activity before it becomes an infestation. One-time treatments work well for isolated problems, but recurring service is what actually keeps a home pest-free.

The pests we treat most often in Durham are: ants (odorous house, carpenter, and fire ants), subterranean termites (Reticulitermes flavipes — a real risk in the NC Piedmont), cockroaches (German roaches indoors, American roaches from crawl spaces), mosquitoes (April–October is peak season here), house mice and Norway rats in fall, and wasps & yellow jackets in mid-to-late summer. See NC State Extension's Entomology Extension for state-specific identification.

Yes — in most cases. Durham sits squarely in the moderate-to-heavy subterranean termite infestation probability zone on the USDA-derived termite hazard map used in the International Residential Code (Fig. R301.2(6)). NC lenders require a wood-destroying-insect report (WDIR) on almost every residential structure sold, and treatment or annual inspection thereafter is standard for any home older than about 10 years or with a crawl space. Our free termite inspection is a thorough exterior and crawl-space walkthrough — if you don't have active termites, you'll leave with a report showing it. If you do, we'll show you exactly where.

One-time treatment targets a specific active problem — a wasp nest, a sudden ant trail, a roach sighting — and stops there. It's the right choice for isolated issues.
Quarterly service is preventive: we return every 90 days to refresh the exterior perimeter barrier, treat entry points, and catch anything new before it becomes an infestation. On a quarterly plan, re-treats between visits are free. Most Durham homes stay pest-free long-term on quarterly; one-time treatments almost always need repeat visits within 12 months.

Yes.
