The presence of rats into the insulation of your house can occur through a series of factors. Rats are adept at exploiting even minor vulnerabilities in a home’s structure. They can enter your home through small openings, gaps, or cracks in walls, vents, and roofs. Once inside, they navigate through wall cavities, attic spaces, and crawlspaces. Rats seek cozy, hidden spots for nesting. Insulation, especially if it’s old or damaged, provides an ideal nesting material and location. Insulation offers an attractive haven for rats due to its warmth and protection from external elements. If rats find a nearby food source, they will venture deeper into your home, leading them to various insulation areas. To prevent further infestations and damage, it’s crucial to identify and seal potential entry points, maintain your property, and consider professional pest control services to eliminate existing rat populations and protect your insulation from future invasions.
