Among the most common issues that I deal with as a nuisance pest control specialist is a case of squirrels in the attic. It's not a simple thing to handle! The babies are helpless in the attic for the first 6 months of life, and can not be trapped. They need to be removed by hand - the wildlife technician you hire must enter the attic and remove the babies by hand. If you wait more than 6 weeks after they’re born, then the young are nearly adult sized, and move all around just like the mother squirrel, in which case they may be trapped and removed or excluded the same way.
If you want to learn how to get rid of squirrels in your home, you have to find out how they're getting in the home in the first place! Wherever it is, it's easy to mount a particular repeater trap right on the hole, and grab the squirrels as they leave the home - they do several times daily - for water and food. You can even set a one-way exclusion door to allow them to escape, but not get back in. Just make certain the house is squirrel-proof, and that there is no other place to get in, or you're going to be asking me how to get squirrels out of the attic again.
After all of the squirrels are out, you need to seal the entrance point(s) closed forever. If you do not, new animals will move into your attic. All repairs should be made out of steel, so that rodents can not chew their way back in. The squirrels living there left their pheromones behind which may attract new wildlife quickly. There is also the matter of this mess that the squirrels have left behind in the attic, which must be cleaned up quickly.
Eviction is among the best way of getting rid of squirrels in the attic. If you perform all of the building or house repairs initially, and are certain that there are no other entry points for the animals to get inside, you can then mount a one-way exclusion door on the main squirrel entry/exit hole. This allows the squirrels to get out, as they obviously do several times each day for food and water, but can’t get back in. WARNING: Don't do this if you have an active female kid, since she almost certainly has a nest of baby squirrels in the attic too small and young to go out the one way door. You have to wait a couple weeks, about 6 weeks after birth, for them to be almost adult-sized and up and active, and can go out the door. Otherwise, they'll be stuck inside, the mother will chew your home to get back inside, and if she can’t get back inside the young will starve to death.
You might hear it rummaging around and you can smell the odor of squirrel urine also. You will need to eliminate it before it causes extensive damage. If you hear just 1 squirrel, it’s likely a female, and she could have a litter of babies. You want to remove these by hand, or wait for a couple weeks before you hear the young running around.
STEP 1 - Be sure all of the holes leading into the home are sealed closed - assess all roof vents, dormers, soffits, etc.. But leave the main gap (it's usually obvious, large, with chewing about it) open. STEP 2 - When they are out, trapped and relocated, seal up the last entry hole, with steel, so no new squirrels can chew in again. STEP 3 - Clean up the attic, using a special antimicrobial fogging agent.
