Start with the animal if you know it. Mouse control fits small pointed droppings, scratching in walls and pantry raids. Rat control fits larger droppings, burrows and gnawing near foundations, sheds and water. If you are not sure which you have, a rodent inspection identifies the species and the entry points.
Next, match the place. Noise overhead usually means attic and crawl space cleanup is needed after the animals are gone. Garages and cellars, including damp ones near the river, fall under garage and basement rodent control. Burrows, sheds and decks belong to backyard and outdoor rodent control.
Some problems are about the aftermath. A smell in a wall points to dead rodent removal and odor control. Chewed wiring or insulation may need rodent damage repair once the animals are out, though electrical repairs are for licensed electricians. Chewed hoses and nests under a hood call for vehicle and car rodent removal.
Two services cut across everything else. Rodent trapping and removal deals with the animals that are there now. Rodent exclusion closes the gaps so new ones cannot follow. Shops, restaurants and offices can use commercial rodent control, and any active emergency goes straight to the 24/7 line.
