How to Get Rid of Squirrels in Attic

Squirrels may be furry and cute when you are out on a hike, but these small creatures can cause big problems if they decide to make your attic their home. If you are wondering how to get rid of the squirrels that have made their home in your attic, you aren’t alone. Many homeowners struggle with squirrel infestations and effectively dealing with this wildlife removal will probably require the services of a professional for rodent proofing.

Understanding the Damage Squirrels can Cause

You might scoff at the idea that squirrels living in your attic can pose a serious problem, but before you completely dismiss the threat that squirrels face, let’s take some time to fully understand the scope of the problem.

ully understand the scope of the problem.

Exactly how do animals get in the attic? Rodents like squirrels are attracted to attics and other unfinished spaces in houses because they offer a refuge from both predators and the elements. Once squirrels have gained access to your attic and crawl space, they can use it as a base of operations to keep their baby squirrels safe during breeding seasons while the adults go outside of the home to forage for food.

Attics and unfinished spaces are also appealing because they offer a variety of nesting materials for a mother squirrel. Squirrels will turn pretty much anything in your attic into material for a squirrel nest, including attic insulation and items that you might have stored up there. This is one component of the damage that squirrels can cause. Simply by living and nesting in your attic, attic squirrels can cause enormous damage to your insulation or any items that might have been stored in the attic space, leading to a full insulation removal to resolve the issue.

Squirrels are also notorious for damaging electrical wiring and drywall in unfinished spaces. Electrical wiring can be chewed or destroyed to incorporate into nests. Drywall is often damaged from urine and squirrel feces or squirrel droppings left behind as the squirrel colony in your attic gets established. If a squirrel travels or falls into an area they can’t get out of, like a wall, they’ll become trapped there and eventually die. As they decompose, the dead squirrel will give off unpleasant odors and cause damage to the surrounding surfaces that it is resting on.

The Health Risks of a Squirrel Infestation

It is important to understand that squirrels pose a health risk to any residents living in the building. Any wild animal, including squirrels, is capable of transmitting diseases to humans. These pest diseases can be transmitted directly either through a bite or through exposure to the urine and feces of the rodent, or indirectly through the bite of a tick or flea that is carried on the rodent.

Squirrels are foragers, so while they may have a nest in your home they will be leaving it regularly to go out and gather food for their young. Don’t let this idyllic image fool you, these gathering trips are regular opportunities for the squirrels to pick up and bring new diseases back into your home. 

These are some of the most common diseases that can be transmitted directly or indirectly from squirrels and other rodents:

  • Tularemia
  • Plague
  • Leptospirosis
  • Salmonella
  • Rocky Mountain Spotted Fever
  • American canine hepatozoonosis (ACH)
  • Canine ehrlichiosis
  • Bartonellosis
  • Tapeworms

One thing that is notable about squirrels and other unwanted pests in your home is that they bring in fleas and ticks, which can transmit harmful diseases to other animals in your house. If you have dogs or cats living in your home you will want to be very aware of the warning signs of a squirrel infestation or squirrel activity in your attic and move quickly to address it.

How to Tell When You Have an Infestation

Now that we’ve outlined the harm that a squirrel infestation in your attic can cause, you may be wondering how you can tell whether you have one and need to start the squirrel removal process. The earliest indicator that most people have is sound. If squirrels are making their home in your attic, you’ll most likely hear them scratching and moving around. You may hear them walking across your ceiling, or moving in the walls of your home.

Pets like your dogs or cats will probably hear the sounds of a squirrel infestation before you do. If you notice your cat or dog paying close attention to your walls or ceilings, it’s a good indication that you have unwanted pests in the unfinished spaces of your home.

Once a squirrel colony has become established in your home, you may begin to notice strange and unpleasant smells. This is one of the later signs of a squirrel infestation in your attic. As squirrels live and nest they will produce urine and squirrel feces that will give off an unpleasant odor. At first, you may not notice this unless you are up in your attic, but as the nesting materials and surrounding surfaces become saturated in urine and feces, it will become more apparent.

Depending on the length of time that the infestation has been allowed to take root, you may also notice the smell of decay. Squirrels may die from natural causes or because they get stuck in hard-to-access areas like the walls of your home. Regardless of the cause, as those squirrels decay, a dead squirrel will give off a very unpleasant and unmistakable odor.

Sound and smell are two of the most common indicators of a squirrel infestation, but you may also tell simply by going into your attic. If you have a squirrel infestation you will most likely be able to see the damage caused as they nest. But, given the fact that attics are difficult to access and navigate if you are worried you might have a squirrel infestation it is usually better to have your attic inspected by a rodent proofing service specialist or even a wildlife control professional. Our professional staff at Attic Construction can quickly assess the state of your attic and provide you a detailed description of whether an infestation exists and what steps you need to take to both remove squirrels and prevent future squirrels from infesting your home.

How to Deal With Your Squirrel Problem

There is a wide range of recommendations out there for how to get rid of squirrels in attic. These range from laying out rodent bait to poison them to putting strobe lights in their nesting area to drive them out. Many of these suggestions are questionably effective at best. While sprinkling fox urine around your attic may discourage the squirrels from nesting in your attic, it may not while also leading to further contamination.

To deal with a squirrel infestation in your attic you’ll need to identify how to find rodent entry points to understand how they are coming into and out of your home. This will require a ladder to inspect the eaves, vents on your roof, and any chimneys you might have. Once you have identified where they are entering your home you can begin closing off access points. Some sources recommend closing off all entry points but the one the squirrels use most, then installing a one-way door that allows squirrels in your attic to exit but not re-enter.

If you don’t choose to install a one-way exclusion door, you will probably need to use live traps to get rid of the squirrels that are still in your attic. Squirrel traps are effective, but not easy an easy task. Depending on whether you use a kill-trap or a live-trap, you’ll also need to figure out what to do with those squirrels after you trap them. Simply dumping them in your backyard isn’t wise. You will also need to be very careful since trapped critters can become very agitated and pose a danger to themselves and to you.

If you’ve trapped and removed all of the squirrels from your attic and sealed off all of their entry points, you’ll then need to clean up the contamination left behind by their infestation.

Squirrels and rodents love to make their homes in attics, but allowing them to do so can pose a real risk to the people and pets that live in the home.
