Pest Control in Crystal Lake, IL

Crystal Lake homeowners deal with a mix of pests that comes from living near water, parks and plenty of green space. Whether your house sits near the lake itself, close to Veteran Acres, or in one of the subdivisions along Route 31, we're a short drive from our Cary office and serve Crystal Lake throughout the year.

Every visit begins with a look at the outside of your home, from the foundation to the roofline, so the treatment matches what we actually find rather than a one-size-fits-all spray.

Simple steps help between visits in Crystal Lake: keep boat covers and outdoor furniture cushions checked for nests, trim branches back from the roof, and store firewood away from the house. Your technician will point out conditions like these during the inspection, so you know what's attracting pests to your property and what can be done about it.

What We See Most in Crystal Lake

Stinging insects top the list each summer. Decks, boat storage, play sets and soffits give paper wasps and yellow jackets lots of places to build, and bald-faced hornets often hang nests in trees and shrubs near the water. We provide treatment of active wasp nests; hornet nests away from the structure, such as in a tree, are charged separately.

Humidity near the lake can soften trim and sill plates, which attracts carpenter ants. If you're spotting large ants or small piles of sawdust-like debris, an inspection helps track down where they may be nesting. Carpenter ants are treated separately from plan visits.

Pavement ants are common under the concrete of Crystal Lake's slab and basement homes. Because the colony can live beneath the slab, spraying the foundation outside may not reach it, and an interior treatment may be needed. In the colder months, house mice move inside through small gaps; our rodent exclusion service seals accessible entry points with EntryLock®.
