How To Tell If You Have A Mouse Infestation

Witnessing a mouse in your house is one way to be sure you have a mouse infestation in your home.

However, you may not always see an actual mouse, but they do leave evidence of their presence in and around your home. Here are three specific indications you have a mouse infestation.


Evidence can be their droppings at the back of furniture and appliances, such as a fridge or corners of cupboards. Their droppings are small, dark, and appear like grease marks. You may find them at the back of cupboards, inside cutlery drawers. Older mice droppings will be dry and crumbly, whereas, new droppings will be shiny.

Scratching noises

Sometimes you may hear scratching noises as they move inside wall cavities or along pipelines.

A distinctive smell

Rodents, like mice and rats, leave a foul smell in areas where they dwell. An infestation will likely generate a musty odour that’s hard to ignore.

Hiding places

Mice prefer to make nests in lofts and eaves, as well as behind kitchen appliances and inside cupboards. They tend to nest close to pipes allowing them to scurry away in search of food.

As you may already know, mice are capable of fitting into holes much smaller than their body size and can hide in places well out of sight. Therefore, wall cavities are also a favourite hideout for mice, or a suspended ceiling, where they can go unnoticed for long periods.

When you notice the signs of an infestation, such as droppings, contact a pest control expert as soon as possible. Some people may not think it’s a big problem if they don’t see actual mice, but only see droppings; however, if left unresolved, the problem can escalate as mice reproduce in greater numbers.

Mice may seem harmless to humans, but they do carry diseases and are therefore a health hazard. Furthermore, they can cause structural damage by chewing through wires and insulation.

This is one pest to look out for and take immediate action to safeguard your health and property.
