The general types of these rodents that exist in your home can include the Norway rat, the roof (or black) rat and the house mouse. Roof rats usually stake out attics or cabinets and can climb quite well. Norway rats choose to live in the ground by digging burrows against foundations, tree trunks, and gardens. Their burrows can lead into crawl spaces and small openings around pipes which can enable them to inhabit your kitchens and bathrooms.
No matter the type of rat that lives in your home, you can be sure that it will be attracted to any food item you have in your pantry, especially high-quality food products such as meat and fresh grain. If you have pets, be extra cautious about foods being left out, because rats will smell and detect dog food that is sitting out.
