How Raccoons Enter Walls Crafty critters, raccoons easily find their way into homes through cracks and crevices in building exteriors. Holes in screens, roofs, and siding also entice raccoons, especially since the pests are capable of enlarging existing holes in order to sneak inside. Once they gain entry, raccoons set up dens in secluded areas like wall voids. Dangers of Raccoons in Walls Damage that results from having infestations of raccoons in walls is both costly and dangerous. As essential electrical wiring is located inside walls and raccoons are curious by nature, homes are at elevated risk of electrical fire when the pests are living in wall voids. Residents are also exposed to rabies and other diseases where raccoons are present. Finally, the pests set up latrines near their nests, and the presence of raccoon excrement leaves individuals susceptible to illness and raccoon roundworm. Professional Raccoon Removal As untrained individuals are likely to sustain injuries or fall victim to diseases when they approach raccoons, it is ill-advised to employ over-the-counter methods of control. Instead, contact professional pest control services to remove raccoons in walls. Expert services save homeowners time and money, as well as provide peace of mind because trained technicians offer tips on guarding against future infestations.
