Ok, so last summer we had three squirrels up in our attic ( one mother and two babies), we got alot of advice from our friends before we hired a wildlife control to come get them out.
Number one : don't put moth balls in your attic, this is an old wise tale, did we do this ya but the first hot day ,we woke up chocking because we couldn't take the smell in our home, it took months before our house quit smelling like an old closet...my dh spent an hour trying to retrieve those moth balls ,will never do that again, plus didn't run these squirrels off at all.
Number two : Once they make you their home, they are there even if you take then two miles away, they will be back, you have to take them very very far away, is there a squirrel farm out where you live ? And if there are babies please don't separate them from the mom.
Number three: You better board up ( fix ) where they are getting in at because more will come in there place. You would be suprised what they can crawl though. I payed three hundred dollars for all this squirrel knowledge

. But I was freaked out by them, it sounded as if there were hundreds of them and there were only three small squirrels. We got to where we could even call them and they would peak their little heads out of the side of my gutter/ attic outside.
