Pests will leave behind evidence they are on your property. They can cause terrible damage and an infestation can even be bad for your health. Spotting the signs early can avoid a large infestation and get quicker results.

Finding mouse droppings is a clear sign of a pest problem.

Rats and mice will leave droppings and urine trails. Pest droppings are a warning sign that you have rodents in the house. You might find the droppings behind kitchen appliances or in a closet.

Other signs to look for:


You may notice a scuttling noise that could be a sign of rodents moving around under floorboards and behind walls.

Gnawing marks

If you find electrical cables have been gnawed and gnaw marks on household items, it could be an infestation of a rat or mouse.

They can cause a lot of damage to the house. A rat can gnaw through plaster and wood and ruin your furniture. Soft furnishings tend to get gnawed to make nests with the filling.

It’s time to lay traps or call in the services of a professional.


swallow nest
Look out for signs of nesting which can mean you have a pest problem.

When the temperatures outside starts to drop, many animals come inside and will nest. Mice can get through really small holes into your house, where they will then nest and reproduce.

Identify points of entry for mice and rats and seal them off.

Rodents will use anything they find to build a nest with. You may find bits of shredded paper near the nesting area that they have chewed up. This is a sign of their presence.

You might find nests in the eaves of your house or in the attic or other evidence of nesting. The nests could belong to bees, wasps, squirrels, or birds. It is worth calling in pest control to find out what you are dealing with.

Grease marks

Rodents run along the edge of walls when moving about. When they do this, they leave grease and dirt marks behind.

Holes and tears

Holes in the packaging of food could be evidence you have a rodent on the loose. Keep food items in metal containers to prevent pests from eating the food.

Shed skin

If you find this on shelves, floors, or work surfaces, these are signs of insects at large.

Outside in the yard


Mosquitoes are attracted to the water where they lay their eggs. To prevent this, remove standing water from your yard, as they tend to fly over and spot it.

Mole holes

Moles will dig up the lawn to search for worms and bugs. You will see mounds they have made on the lawn.


Check along fences and cracks in concrete for piles of coarse soil, with a small hole in the top. You may see ants going into the hole; this is their nest.
