Local pest control in St. Charles

Your St. Charles exterminator, close to home

St. Charles is home for McCarthy Pest & Termite Control. Our headquarters sits on Sycamore Drive in the Harvester area, which means most St. Charles homes are only minutes from a technician. When you call with a wasp nest over the front door or ants marching across the counter, same-day service is usually possible.

Much of St. Charles was built out in subdivisions from the 1970s through the 2000s along Highway 94, Route 364 and Harvester Road. Those homes are now old enough that wood decks, settling slabs and mature landscaping give pests easy footholds. We build a plan around how your home is actually built, then guarantee it between visits.

We serve homes and businesses throughout St. Charles (ZIP 63301, 63303 and 63304) with residential pest control, commercial service and termite protection, all backed by our free re-treatment guarantee.

What we see most

Common pests in St. Charles homes and businesses

Odorous house ants

The most common call we get from St. Charles kitchens. Colonies nest under mulch and slabs and move indoors after heavy rain or a hot, dry spell.

Brown recluse spiders

Missouri is prime brown recluse territory. They hide in basements, storage boxes and garages, especially in finished lower levels.

Subterranean termites

Decades-old slabs and wood decks in established subdivisions are where we find active termite tubes most often.

Wasps and yellowjackets

Mature trees, playsets and soffits give stinging insects plenty of nesting sites from late spring into fall.
