Raccoons that have established a nesting site inside your Lexington home are not a nuisance you can afford to ignore. Within weeks of colonizing an attic, a family of raccoons can shred and compress entire sections of insulation, reducing your home's thermal efficiency and dramatically raising heating and cooling costs. The degradation of insulation is not cosmetic — it's a structural and financial loss that compounds every month you delay action.
Far more dangerous than insulation damage is the risk of electrical wire chewing. Raccoons gnaw through cable insulation regularly, exposing bare wires. In homes across Lexington, improperly addressed raccoon damage has been a contributing factor in attic fires. A single exposed wire arcing against dry wood framing can ignite a blaze faster than a smoke detector can alert your household.
The biological contamination raccoons deposit is a serious public health hazard. Raccoon feces harbor Baylisascaris procyonis — a roundworm whose microscopic eggs can remain viable in soil and building materials for years. As droppings dry, spores become airborne and can enter your HVAC system, spreading through every room. The volatile weather patterns in Minnesota — hot summers and cold winters — accelerate drying and spore dispersal, making attic contamination especially dangerous in this region.
Raccoons nesting in chimneys represent a separate but equally urgent problem. Female raccoons are drawn to chimneys as secure, warm den sites for raising kits. Their nesting material — leaves, debris, fur — creates significant fire risk. Attempting to light a fireplace while a raccoon nest is present is extremely dangerous and can result in a chimney fire. Minnesota's dry seasonal conditions heighten this risk considerably, making prompt chimney inspection and removal an urgent priority for any Lexington homeowner who suspects raccoon activity.
