How To Identify Mice Infestations

We all have a certain image in mind when we think of mouse holes, and it usually comes straight out of Tom & Jerry – a perfect half circle in the baseboard. In reality however, mouse holes are not quite so endearing. They are messy and often a sign of a heavy infestation. In this article, we’re going to help you find and identify these mouse holes.

What mouse holes actually look like

Mouse holes can be hard to spot. They are not very large openings and they do not have an obvious shape. Instead, you will have to look for them in damaged sections of the paneling or wall. Mice will also use the gaps they can find between building materials, spaces created by crumbling mortar, or cracks in the foundation. These holes may be very small, and they will have an irregular shape. House mice purposefully look for hidden areas for their nests, so you have to be thorough in your search.

Other signs of a mouse infestation

Mouse holes are just one of the signs that you may have a house mouse infestation. However, these holes can sometimes be in very unexpected places, since mice are excellent acrobats and climbers. This means that you will have to be aware and keep an eye out for other signs as well. These signs may include:

• Droppings – House mouse droppings look like brown or black seeds, and when they are fresh, they are somewhat shiny.
• Bits of hair – Mice shed fur on a regular basis as they brush against surfaces. If you find short hairs that are gray, tan or black colored, you may have an infestation.
• Oil stains – Mice secrete oils in their fur, so you may notice streaks on the floor, or along the walls.
• Strong smell – Mice leave a urine smell, so if you sense it around the home, and it’s not due to your pets, it might be due to an infestation.
• Debris around the home – As mice carry material to build up their nests, they will drop some of it along the way. This debris may include paper, wood chips or rubbish.

Existing holes

Sometimes mice do not even have to create their own passageways, because they already exist in the walls of your home. These existing holes are usually found in access spaces for plumbing, electrical wiring, HVAC systems, conduits, vents, and cable/phone lines. For example, it is not uncommon for mice to find entry into the home through the plumbing near the bathroom or kitchen sink. Make sure that you keep an eye out for these known points of infiltration.
