The answer to 'rat nests' is that rat nests are a common problem for homeowners, indicating the presence of a rat infestation. Rat nests are typically made of shredded materials like paper, cardboard, or insulation, and are often found in attics, walls, or other hidden spaces within the home. Symptoms of a rat nest include strange noises, droppings, or damage to insulation and wiring.
To address a rat nest, it's important to first identify and seal any entry points the rats may be using to access the home. This can be done through DIY methods like caulking and steel wool. However, if the infestation is severe or the nest is difficult to access, it's best to call a professional pest control technician who can safely and effectively remove the nest and treat the underlying problem.
