A squirrel in a chimney may sound like gnawing since they like to chew through a wide range of materials. You may also hear a persistent scratching sound if they’re trapped inside and unable to get out themselves. Other evidence of a squirrel in your chimney includes holes on or around your chimney as well as droppings or damage to roof shingles or wiring.

You can use commercial repellents to help deter rodents, but they often have mixed results. A better solution is preventing rodents from getting under your home in the first place. Using steel wool or foam sealer, plug all potential entry points like gaps and cracks in the foundation. 

Also, consider installing hardware cloth or wire mesh over vents, utility openings, and any openings under the porch or foundation. Regular inspections and maintenance will aid in early detection and prevention, ensuring a rodent-free environment beneath your house.

Finding mouse droppings without seeing any mice is a common sign of an infestation because mice are nocturnal and skilled at hiding from humans. Droppings are often the first and most visible evidence of their presence. The location, quantity, and freshness of the droppings can help you determine where the mice are most active and how severe the infestation might be. Since mice are active at night and often travel through hidden pathways like inside walls, you may not see them directly. It's important to look for other signs of an infestation, such as gnaw marks, scratching sounds, or greasy trails along walls. If you find droppings, consider setting traps or contacting a professional exterminator to address the issue.

Exterminators can get rid of your current ant problem, but they won’t prevent ants from coming back. So it’s important to implement ant preventatives to avoid future infestations.

The primary reason ants enter your home is to find food. If they can’t find any, they won’t survive. So, the most effective way to prevent ant infestations is to clean, clean, and clean some more. 

Keep your kitchen sparkling and wash your dishes immediately (or at least give them a quick rinse and wash off leftover food). Take out your garbage and compost as often as possible and tightly seal all your kitchen containers, especially the mason jars you use to hold your sugar—sugar is gold to ants.

You can also hire a local handyperson to help you prevent future ant infestations. The handyman can seal cracks and fix leaks throughout your home, which will keep any ants from entering.
