To help you identify an infestation before it gets out of control, here are five common signs that may indicate a rodent problem. 

Droppings 

One of the telltale signs of a rodent infestation is droppings. Depending on the type and size of the rodent, droppings can be anywhere from 1/8 to 1/2-inch long and are usually dark brown or black. They will often be found concentrated around nests, food sources, and areas where rodents regularly travel. 

Chewing Damage

Rodents have sharp incisors that allow them to chew through wood, plastic, aluminum siding, and even electrical wires. If you notice that your walls or cabinets have been chewed through or if there are visible holes in the baseboards or other woodwork, rodents likely are to blame. 

Noise at Night

Since rodents are primarily nocturnal creatures, you may hear them scurrying about at night when everything else is quiet. This noise could sound like scratching or gnawing and is likely coming from within walls or ceilings as rodents search for food and nesting materials. 

Odor

Another sign that a rodent might have set up camp in your home is an unpleasant odor similar to ammonia or burning rubber coming from behind walls or under floorboards. This odor is caused by urine and feces left behind by rodents as they make their way around your home. 

Nests

A final sign of an infestation is finding nests made out of shredded paper or fabric fibers in dark corners and crevices throughout the house. These nests are usually built using materials such as insulation, shredded newspaper, fabric scraps, twigs, and leaves – anything that’s available in their environment!
