Although some people find mice to be cute as pets, what is not cute is when they are infesting your home! Unfortunately, mouse infestations have been increasing throughout Los Angeles and Orange County. Once they infiltrate and make your home their home, it can be very difficult to get them out. 

The mouse is a small two to four-inch rodent which is often found in your attic, garage, lofts, under appliances, and even the inside of your walls. Mice are ruthless omnivores. They will turn to eat each other should their source of food run out, and the last thing you want to do is find carnivorous mice in your walls! 

Rather than using home solutions to solve your problem, it is essential preventative measures can be put into place. After doing everything you can yourself, if you truly want to stop a mouse infestation, you should always look to a professional.

Why Do Mice Enter Your Home? 

Similar to how you want to remain warm in the winter, mice are also attracted to the warmth of your home. Mice can fit into tiny holes as small as a dime, which allows them to enter your house unnoticed. Common methods that mice might find an entry into your home include:

Torn Vents

Whether you have broken vents in your laundry room or attic, any small vent such as a crawl space vent allows a place for mice to enter. These spaces allow mice to nest within your walls which might allow you to notice the dreaded scratching noise often heard in the middle of the night. 

Cracks in Your Foundation

Cracks in the foundation of your home are common, and occur when the ground settles and the foundation shifts. Although you might think a small crack only ¼ inch in size is harmless, mice can squeeze through these easily. Another reason that this occurs is due to water erosion, so it is important to inspect your home each year. 

Intentional Weep Holes

Although weep holes are placed between bricks purposefully when building homes, they allow the opportunity for mice to enter. These are important holes, as they help to prevent moisture from forming behind the bricks, but you should always ensure there are screens blocking them. This is a very common entryway for mice.

Unsealed Pipes

Sump pumps and other plumbing is essential to your home, but sometimes a contractor or plumber does not seal them as they should. Mice have no issue entering through the gaps around piping. Be sure to walk around your home and examine these areas. Seal them off if necessary.

Signs of Mice in Your Home 

  • Scat: The most obvious sign of having a mice infestation is scat, also known as droppings. This is the waste product of mice and will be a telltale sign that you are dealing with an infestation.
  • Tracks: Mouse tracks or footprints can be a sign to see where the mice are traveling. This can be helpful to find their nests. Look for footprints, but also for tail prints as well. You can use flour around the areas you think they might be walking through, and wait for the trails to appear.
  • Bite marks: Mice love to get into human food and chew on different materials. Look on the packages of different foods, as well as paper products, cardboard boxes, as well as pipes, ducts, and vents.
  • Sounds in the night: Mice are nocturnal which means they will be more active at night than any other time. If you hear a faint scratching or gnawing noise then you most likely have a few critters in your home.
  • Unusual behaviors from your pet: If your pets are suddenly barking at the walls or sniffing around cabinets that they normally would not do, they may have detected mice in your home.
  • Strange holes: Look for burrows around your home around the outside. This might give you a clue as to where the mice entered your home.
