The Best Way to Eliminate Squirrels in Attics, Crawlspaces, Basements, Garages, Cars & More

This works

Had two holes a foot wide chewed into my attic and the critters partied every night. Had exterminators come in and offer to plug up the attic for $3200. Searched for an alternative and found Evictor. Figured it was worth a try and bought two 10K strobes to cover the attic. Have not heard a peep since I installed them. Been a year and need to replace the bulbs. Not cheap as bulbs go but I can buy a lot of them for $3200.


Squirrels see your attic as a nice place to live and they want to be there. A nasty environment must be created, an environment so nasty that they will be repelled and not want to be there.

The EVICTOR® is a high intensity strobe light designed for squirrels living in attics, crawlspaces and other darkened areas. 

EVICTOR® strobe lights hang in an attic or crawlspace from a beam or rafter and emit a high intensity strobing light that will get rid of any squirrels living in your attic or crawlspace.

Installing the EVICTOR® 

The pulsing EVICTOR® strobe light is too bright for a squirrels sensitive eyes and disrupts their natural living cycle.  After hanging the EVICTOR® strobe light in an attic squirrels usually vacate within 1 to 2 days.

How many EVICTOR® strobe lights will you need to evict squirrels in your attic or crawlspace?

Each 10K unit covers 300 square feet or a 15' x 20' area.  You will need to measure your attic or crawlspace and determine the approximate number of EVICTOR® strobe lights needed.

Many homeowners with a single story or split level home need only 1 light to permanently evict squirrels in their attic.

Prepare Your Attic to Get Rid of Squirrels

Hang each EVICTOR® strobe light at about 3 feet above the floor in a central location.

You can also try to hang the EVICTOR® near the squirrel nest, if you have located it in your attic.

If squirrel babies are present, and the mother squirrel has not removed them, she will come back for her babies.  In this instance it may be necessary to move the EVICTOR® strobe light away from the nesting area to a more central location.

Each EVICTOR® should plugged directly into an outlet.  A GFCI outlet is recommended.  We also recommend installing a switch between the outlet and the breaker that is located near the entrance to the attic or just outside the attic door.

The EVICTOR® does not have an ON/OFF switch, so a switch must be installed to turn the outlet ON and OFF.

You can have an electrician put in a switch outside your attic for the outlet(s) that are dedicated for EVICTOR® use.  This way, once you leave your attic or crawlspace you can switch on the EVICTOR®

For the EVICTOR®  strobe lights to work properly, the space must be uncluttered and as dark as possible.

No other light source should be present to interfere with the performance of the EVICTOR® while in use.

If there are windows in the attic, tape cardboard over them to block off any outside light.  Gable vents may not emit enough light to interfere with the EVICTOR®.

Do not seal the Entrance/Exit holes for at least 30 days.

Allowing the squirrels to enter and see the Evictor® in use is necessary and will allow them time to relocate their nest to a nearby tree.  Leaving the entrance and exit holes open will also allow time for squirrels to carry their babies to the new nest.

EVICTOR® strobe lights are the most effective method to evict squirrels from your home without killing, trapping, poisoning or other harmful methods.  Squirrels are not harmed in any way by the EVICTOR®.

Replacement bulbs are easy to install.  Don't be afraid to use the Evictor through the entire year.

If necessary, close the holes thirty days after your EVICTOR® strobe light installation.

DO NOT close holes before you've started the process in this guide.  You want to avoid additional damage!  Squirrels will chew new holes to gain entry if the holes are closed too soon.

However, you want to leave a small opening for the squirrels to SEE inside your previously occupied attic/crawl space.

This way, whenever a squirrel ventures back to your house, a view of the strobe light is a REMINDER that this is one place they do not want to go back into.


Having the EVICTOR® Strobe Light visible to any returning squirrels serves as a reminder that your house is a place they don't want to live in.

The EVICTOR is used by one of the top 5 largest pest control companies in the nation; Massey Services Inc. to get rid of squirrels, roof rats, and feral cats in attics, crawlspaces and darkened areas in residential homes and commercial buildings.

On one of our tests in the past month we have placed your (EVICTOR® 10K) in a squirrel infested attic in Lake Mary, Florida. With only one unit, the (Evictor Strobe Light 10K) elimated squirrel noises at one end of the home but forced the squirrel(s) to the other end of the home.

We then placed the unit at the other end of the home and in a few more days the squirrel(s) had completely left the attic. We continued to run the unit for over 2 weeks after the squirrels left, and since no further activity existed for such a long duration, we removed the unit last week.

In this test we have left the squirrel entry points unsealed to see how long it might take before any squirrels re-enter. It's been one week now and they haven't re-entered! I'll keep you posted.


Follow up - Exclusion Methods

After installing the EVICTOR® Strobe Lights in your attic or crawlspace, a squirrel's entry and exit points may be closed or sealed up with hardware cloth or steel mesh. You may also try to fix any damaged fascia board with aluminum capping for aesthetics.

Adding Squirrel Boxes

Giving the squirrel another home is essential in the squirrel eviction process. Each squirrel may have multiple nests and if a tree was recently removed that had a squirrel nest it will have no other options but to try and find a way to keep warm. This can mean entering people's homes, attics and crawlspaces. Adding a Squirrel Box to high fence line or nearby tree high off the ground can help encourage the squirrels living in your attic to leave.

Using Fox Scent

Homeowner's report increased success at evicting squirrels when fox scent is sprayed along gutters, roofs, or ridge lines where squirrels can be spotted traveling regularly.

A natural predator's scent may be the only thing a squirrel needs to get the message that your house is not where they are supposed to be

Do not Trap or Poison Squirrels

Sometimes the best advice to give is to help define what not to do. Trapping and Poisoning squirrels is a risky and ineffective method to achieve a permanent solution to your attic squirrel problem. Trapping and poisoning squirrels is also the most advised method for professionals and homeowners.

A baited trap can leave the smell of food in an attic and attract additional squirrels or other small wildlife. If you trap one squirrel, another may take its place in your attic.

Many pest professionals are trained to trap and remove wildlife in attics and crawlspaces. This can have many harmful consequences including leading to a mother squirrel being separated from baby squirrels left to die in the attic. It also doesn't stop the most common problem of having squirrels come and go into an attic.

Releasing a squirrel many miles away from your home doesn't stop the next squirrel from entering your attic.

Squirrels often mark territory with urine and fecal matter. This material will likely still have an odor to a squirrel even when cleaned up by a professional. That odor will attract other squirrels to an attic to make a nest.  

A squirrel may chew wiring and start an electrical fire without ever going to a baited trap.

Poisoning squirrels is dangerous to wildlife and can kill pets or harm other nearby wildlife. Squirrels are prolific in wooded areas and poisoning squirrels in attics can lead to a never ending battle with a messy clean up.
