Attic Window

We don’t typically visit the attic, other than to shove in a few boxes once in a while. This makes it an ideal refuge for pests and wild animals. It offers protection, it’s close to food sources, and it’s warm and cozy. Pest control may be necessary for this area of your home. Let’s learn about the most common pests that find their way into attics – just like yours – across the nation.



Bats are types of creatures that are naturally drawn to certain areas of the home – such as chimneys and attics. These animals have the capability of detecting small changes in air pressure, which also allows them the ability to discover entryways into structures.

Once inside, they gravitate towards walls, attic spaces, and confined areas. They are able to use spaces as small as a half-inch to get inside your home. While naturally drawn to caves, an attic is a warmer, more dry option when it comes to shelter.

The droppings left behind by bats can result in damage to your home and create a foul smell. Additionally, fungus may grow in the feces that can result in the development of respiratory illnesses.

Due to laws that protect bats, you are required to contact a professional for removal.


Baby Birds in Nest

Birds seek out high and dry locations that are free of natural predators. If they discover a broken vent, a crack in a wall, or another gap they are able to fit in, they will enter and set up residence in your attic to nest and safely raise their family.

While birds are not typically considered to be dangerous pests, they are a nuisance. Additionally, the feathers, droppings, and nests that they create have the ability to attract other types of pests. Examples include breed flies and even carpet beetles.

Furthermore, some types of bacteria may be found in bird droppings that can detrimentally impact your health.

Carpenter Ants


Carpenter ants are naturally drawn to wood for the purpose of nesting. It is common to track points of entry through cracks, attic vent systems, electrical wires, pipes, and phone lines.

Ants prefer wall voids, doors that are hollow, foam-based panels, windows, and similar areas. Hearing rustling sounds in the wood, seeing wood shavings, and actually seeing the pests indicate an infestation.

These colonies are quickly able to create satellite nests; therefore, if an infestation is identified, it is essential that you have your home treated immediately.

Cluster Flies

To termites, the attic is a buffet of free wood. Attics contain a lot of old and untreated wood. Additionally, there may be undiscovered rotted wood pieces. All of these are highly attractive to a termite colony.

If left untreated, your home can suffer an immense amount of damage from termites.

Given the fact that the attic is often left alone for long periods of time, it is advised that you inspect the area at least once a month to determine if an infestation is present.

Common signs include wood shavings that resemble sawdust, wing droppings, and mud-based tunneling systems running along walls.

It is highly advised that a termite treatment is done as a preventative. Once an infestation is identified, it may be too late.
