The answer to 'rodent nests' is that rodent nests are a common sign of a pest infestation in the home. Rodents like mice, rats, and squirrels will build nests in attics, wall voids, crawl spaces, and other secluded areas to shelter and raise their young. Signs of a rodent nest include droppings, gnaw marks, and visible nesting materials like shredded paper, insulation, or fabric.
While it's possible to address a minor rodent issue yourself, it's generally best to call a professional pest control technician. They have the expertise and equipment to properly identify the type of rodent, locate all nesting sites, and implement a comprehensive treatment plan to eliminate the infestation and prevent future problems.
