Unusual Pet Behaviour

If the cats and dogs seem to be acting funny, it’s likely because they already know something’s not right. Their acute sense lets humans know something is out of place, which they’ll communicate in their own way.

Acting restless, scratching the wall, growling at corners, showing extreme alertness, and barking at seemingly empty spaces are all ways they’re letting you know there are signs you have a mouse.

Torn Cardboard and Wood

Have you noticed different items around the home have chewed edges? Torn cardboard boxes and desk papers, as well as gnaw marks on railings or wooden furniture, are often the handiwork of a mouse. Gnawing is a common rodent habit used to trim teeth, and mice will resort to any wooden structure, electrical wiring, and other material to do so.

If you notice marks on food packaging, get rid of the container and food immediately to avoid further contamination.

Mice also use papers, leaves, and fabric to build their nests, and they’ll take advantage of these materials lying about to build a warm site.

Small Droppings

Mice have to go to the bathroom, and it’s pretty frequently. Their small, pointed droppings are less than a centimetre in length and often scattered throughout the home. Older ones are more likely to crumble, while newer ones are darker in colour.

From roof soffits to interior walls, mice like different spaces to live. Dark, secluded areas are perfect. The greatest number of droppings are found in feeding or nesting areas, often in places near food packaging, drawers or cupboards, and under sinks. Take precautions for safe disposal.

Bad Smell

Mice’s hygiene practices are less than impressive. Their urine has a musky smell, and their pile of droppings will eventually create a bad odour. If you’ve noticed a particularly unfamiliar smell and aren’t sure of the culprit, it’s one of the signs you have a mouse. The stronger the stench, the closer you are to the nesting site.

Another explanation could be a dead mouse, whose decaying carcass creates its own funk. If a mouse got stuck or trapped in a wall, it’ll start to smell over time. These tiny guys know how to cause a stink.

Scampering and Squeaking

What’s that noise? While mice aren’t as noisy as other rodents who may take up residence in your home, they aren’t completely silent critters. These nocturnal rodents use the night to explore, and you’ll likely hear them scratching various surfaces to get what they want.

Their flexible bodies allow easy movement from one part of the house to another, which causes an irritating sound as they scamper about.

Tracks and Marks

We’ve already mentioned mice’s lack of hygiene. This becomes more evident when they move throughout your home. Common paths include interior walls, electrical wires, pipes, and building foundations. As they rub along the walls of your home, their oily fur leaves a residue. If rub marks smear, they’re fresh.

Dusty parts of the home are likely to show signs of tiny prints, indicating a rodent went by. If you suspect you have mice, leave a thin layer of flour in the area. Check back the next day for footprints.
