Protecting Your Crawl Spaces from Subterranean Pests

Protecting Your Crawl Spaces from Subterranean Pests

Crawl spaces are dark, damp, and undisturbed, making them ideal nesting locations for ants, centipedes, sowbugs, and spiders. Over time, these structural invaders migrate upward into residential kitchens and wall voids. To protect your home shingles and beams, learn about our specialized carpenter ant treatments.

The Pathway of Crevice Migration

Concrete foundations dry out, crack, and settle over time, opening small voids that lead directly into the floor sill plates. Standard crawling insects utilize these pathways to nest safely away from dry outdoor air. Sealing concrete gaps with durable silicone sealants is the first physical line of defense. Check out our seasonal programs on our services overview page.

Applying Precision Foundation Treatments

Our technicians apply targeted barrier treatments and residual dusts inside crawl space crevices to establish a dry boundary line. This blocks insects from establishing active nest paths. Learn more about our company history on our about us page.

Crawl Space Moisture Mitigation

Crawl spaces act as humidity reservoirs. Laying heavy-duty plastic vapor barriers across dirt floor zones prevents soil moisture evaporation, drying out the crawl space to discourage wood-destroying insect colonies. Review custom options or contact our Niagara office directly on our contact page to set up an inspection. At Jargelo Pest Control Services, we protect crawl spaces and foundations with ultimate care.
