The answer to 'why is my mouse recurring problem' is that mice are persistent pests that can be difficult to fully eliminate, especially if there are ongoing sources of food and shelter in your home. Mice are highly adaptable and can find new ways to get inside, reproduce quickly, and re-establish themselves even after you think you've gotten rid of them.
Common causes of recurring mouse problems include cracks or holes in your home's exterior that provide easy access, accessible food sources like pet food or crumbs, and nesting spots like attics, walls, or basements. Symptoms include droppings, gnaw marks, noises at night, and damage to your property. To solve a recurring mouse issue, you'll need to address the underlying causes through a combination of exclusion, elimination, and prevention measures.
