Your home’s foundation is its backbone. Everything built on top of it is at risk of structural damage and reduced property value when it is compromised. Most Naperville, IL homeowners think of foundation damage as a water or soil problem, but pests can also be destructive contributors. Some insects and rodents work quietly over months or years. Homeowners may only notice pest-related damage when it becomes costly. Thankfully, they can rely on experts from Pointe Pest and Pointe Pest Control to help address active infestations and prevent future issues. Here is a look at six pests that pose a threat to your Naperville, IL home’s foundation:
Subterranean Termites
Subterranean termites are the most destructive pest on this list. These insects live in underground colonies and build mud tubes to travel from the soil into the wood structures of your home. Termites are a serious concern because:
They can target wood in direct contact with soil, including wood forms left behind during construction.
They can compromise floor joists, support beams, and wood framing near the foundation.
Colonies can number in the hundreds of thousands, and damage often goes undetected for years.
You should prioritize termite prevention if your home has a crawl space or wood elements near ground level.
Carpenter Ants
Carpenter ants excavate wood to build their nests. They prefer wood that has been softened by moisture. This makes foundation areas and crawl spaces particularly attractive to them. Carpenter ants in Naperville, IL homes often establish satellite colonies in wood near basement walls, damaged wood around window wells, and structural lumber exposed to moisture over time.
Carpenter ant colonies can expand quickly if not addressed early. They hollow out wood as the population grows, weakening key structural components.
Odorous House Ants and Pavement Ants
Pavement ants nest directly under concrete slabs, sidewalks, and foundation edges. Their constant excavation of soil beneath concrete can create voids that shift or crack the slab above. You may notice:
Fine dirt or sand pushed up through cracks in the concrete near the foundation.
Ant trails along the base of exterior walls.
Ant activity near expansion joints in driveways or patios.
The damage from these ants develops slowly, but the long-term impact on foundation stability should not be ignored.
Mice and Rats
A mouse can squeeze through an opening the size of a dime. Rats can gnaw through concrete, brick, mortar, and wood to create or expand entry points into your home. Their burrowing behavior can compromise your foundation. Rodent activity near your foundation can:
Create tunnels that destabilize the soil supporting your home.
Widen existing cracks, allowing water intrusion that accelerates damage.
Damage vapor barriers in crawl spaces, leading to moisture problems that attract other pests.
Colder months often drive rodents indoors, making fall and winter important times to inspect for entry points.
Voles
Voles are outdoor pests that burrow extensively through soil. Their tunnel networks can run beneath foundations and weaken the soil that supports your structure. Signs of vole activity near your foundation include:
Visible runways or narrow paths in grass near the home’s perimeter.
Small burrow openings close to the foundation edge.
Damage to plant roots and landscaping near the house.
Voles rarely enter homes, but their underground activity can still cause serious structural concerns.
