A thorough home inspection will help you identify the type of rodent your dealing with and what they are doing, what is bringing them inside and most importantly, what rodent control solution is needed to eliminate the problem.
Dropping are the most common sign that you have a problem. A typical adult mouse produces 50-75 dropping each day. You can find literally thousands of droppings from even a small infestation. Droppings appear as small black pieces of rice but with pointed ends.
Evidence of gnawing is a sign that you have a rodent problem. Rodents tend to gnaw on wooden structures such as corners, floor joints, and wall studs. Cardboard and cartons are also a favorites for mice.
Other indicators that you may be dealing with a rodent problem are strong, musty odors, or a urine scent. Scratching and clawing are common sounds coming from within walls or the ceiling above or under floorboards. Cats and dogs may act excited at the areas rodents may be present.
