The answer to 'why is my rat nests' is that rats are likely nesting in your home or on your property. Rats are common pests that seek out warm, sheltered areas to build their nests and raise their young. Some common causes of rat nests include access to food sources, cracks or openings in your home's exterior, and lack of proper sanitation or pest control measures.
Symptoms of a rat infestation may include seeing the rats themselves, finding their droppings, hearing noises like scratching or scurrying, and spotting signs of damage like gnawed wires or insulation. To address a rat problem, it's important to identify and eliminate their food sources, seal up any entry points, and use traps or other control methods to remove the rats. In some cases, it may be best to call in a professional pest control technician, especially for severe infestations or if you're uncomfortable handling the situation yourself.
