A nightmare for homeowners, mice infestation can be a complex problem. However, the complete eradication of rodents can sometimes be a never-ending battle. A part of the solution is to know the extent of the infestation. To figure out this part of the equation, the unwelcome visitors will leave tell-tale signs of their presence. Here are some common signs of mice infestation:

Droppings

Look for mouse droppings. Old droppings are gray and dry to the touch. Fresh droppings are dark brown to black in color and moist. Typical locations for droppings are under sinks, near where food items are stored, and along walls. Dark droppings are an indication of a current mice infestation. The most significant droppings are usually located near food sources and nesting areas.

Gnaw marks

The presence of gnaw marks on food packaging is a clear indication that mice are feeding on household items. Also, small holes with gnaw marks in drywall or ceilings are generally found around areas where mice are gaining entry. It’s essential to determine if these marks are new or old. Older gnaw marks on drywall will darken as they age. Small holes with a light color signal that they’ve been created recently.

Foul odors

The sudden presence of foul odors could be the result of mice. Mouse urine smells like ammonia, so the presence of this smell indicates mice infestation. A dead mouse, perhaps stuck in a wall or a hidden location, has a sharp, pungent odor.

Scratching noises

Hearing scratching noises, especially at night, is typical of mice infestation. These sounds can come from underneath floorboards, walls, cabinets, and even the ceiling. An obvious indicator of mice is muffled squeaking.

Watch the pets

Dogs and cats can signal an infestation of mice. With higher hearing and olfactory senses, pets can detect unusual movements and smells that humans may not notice. For example, a cat or dog that is abnormally or obsessively interested in a kitchen cabinet or a wall is probably due to the smell of an intruder or hearing scurrying sounds.

Nests

Mice, and other rodents, will use shredded paper, bits of fabric, and even dried leaves and grass to build a nest. Therefore, finding a small mound of these items signifies past or current mice infestation. Likewise, those with accompanying droppings or urine smell indicate a current problem.

Safeguard the home

Once an infestation is discovered, consult a professional. Mice infestation can wreak havoc on a home. Often challenging to eliminate, it’s best to consult a professional pest control specialist. Not only are they experts in eradicating the problem, but a pest control specialist can also help to prevent mice from returning.
