Older homes might have charm and character, but they might also be more likely to have pests. If you hear scratching in the walls or spot droppings, rodents may be telling you something important about the condition of your home’s exterior.
Pests don’t just appear randomly. They’re opportunists. When siding, fascia, or roofing materials begin to deteriorate, small gaps and cracks form. These openings create easy entry points, especially in aging homes where materials may have warped, rotted, or separated.
Rodents can squeeze through incredibly small spaces. Mice only need a dime-sized opening. Loose vinyl panels, cracked siding, and failing caulk around windows are common access points. If pests are getting inside, it might be a sign that your siding system is no longer properly sealed.
Insulation is another concern. Once rodents gain entry, attics and wall cavities provide warm areas for nesting. Unfortunately, they often tear up fiberglass or cellulose insulation to build nests. This reduces your home’s energy efficiency, leading to higher heating and cooling costs. Damaged insulation may also trap moisture, increasing the risk of mold and wood rot.
When exterior systems aren’t functioning well, pests exploit vulnerabilities.
Rodent activity can serve as an early warning sign. Instead of simply addressing the pest problem, you can schedule a professional exterior inspection. Replacing damaged siding, sealing entry points, upgrading insulation, and ensuring proper ventilation can improve comfort, energy efficiency, and curb appeal.
If your old house has new scratching sounds, or if you spot droppings, it is important to call a professional for pest control. After, you should call an exterior remodeling professional to evaluate what your exterior is trying to tell you.
