Attics give pests an abundance of shelter

How often do you go up to your attic? Probably not as much as the pests that like to call it home.

Airy attics, away from the hustle and bustle of the main home, provide an abundance of shelter for pests looking for peace, quiet, or a place to raise their young.

Here are a few of the common pests to guard against when it comes to your attic, alongside some top tips to prevent your home from getting infested.


Rats and mice invade homes seeking food, water and warmth, squeezing through tiny holes and cracks. In urban areas, rats colonize in isolated places like attics, before following the scent of food to your kitchen.

Rodents contaminate food, can introduce parasites, and can transmit serious diseases. Rats and mice will also do physical damage to your home, gnawing on materials, burrowing through walls and chewing through electrical wiring.

To prevent a rodent invasion in your attic:

  • Seal any cracks or holes with caulk or foam.
  • Fix leaky soda or ice machines and HVAC units.
  • Keep your attic sanitary.


Bats seek out places similar to their natural habitats, which is why it’s common to find them in the attic.

They are able to enter through open windows and doors, broken or poorly fitted screens, and loose or missing roof shingles.

However, bats pose several health risks to humans, bat droppings also stain and damages walls and floors in homes.

To prevent bats from infesting your attic:

  • Seal cracks, screen chimneys, and repair damaged screens.
  • If you find a bat in your attic, call a professional pest control service to ensure the bat is removed safely, humanely, and legally.


Most squirrels know they can get a constant supply of food and shelter near human homes and since they can scale buildings with ease, squirrels often enter buildings through vents or openings around roofs, setting up home in the attic.

As they venture through your home, squirrels can do a huge amount of damage, chewing on electrical wiring, ripping insulation from walls, and keeping residents up by being noisy. Squirrels can also carry parasites that spread diseases to humans.

To stop squirrels entering your attic:

  • Seal any entry points.
  • Remove all overhanging branches that might give them access.
  • To safely and humanely have a squirrel removed, you’ll need a professional pest control service.


Due to the abundance of shelter in attics, raccoons often climb onto roofs and sneak into homes through chimneys, unsealed vents, or gaps in siding. In fact, females can give birth to up to seven kits every year in your attic or crawlspace.

These pests can do massive structural damage to your property, especially if they decide to raise their young there. They can also carry various diseases dangerous to humans.

To prevent a raccoon invasion in your attic:

  • Cover all possible entrances and seal any cracks or gaps.
  • Remove potential food sources.
  • Trim back any overgrown trees and foliage that might give them easy access to your attic.
  • If you find a raccoon on your property, call a professional pest control service to have it removed safely, humanely, and legally.
