Hello: Your web page is very informative. Can you give me help re a spray that will keep squirrls off a window screen? Or off the patio? The squirrels jump up to the screen from the patio and onto the roof. I’ve had the attic checked and trapped by a pest company, but they didn’t find any squirrels actually in the attic. Thank you.
Once squirrels get active in a given area, they will establish “scent trails” which are a form of trail markers they’ll use for future reference. These markers can be quite strong. And once in place, they’ll be used over and over. In most cases, the best approach is to “trap” out the current squirrels active in the area if you want them gone for good. This would be quite easy as explained in our SQUIRREL CONTROL ARTICLE and after relocating 5-10, you’ll probably reduce the activity next to nothing.
Beyond trapping, I’m afraid the use of repellents to deter them in this same given area could prove futile. Though we have several listed in the above article, I’m not sure any will do a good job on the screens you’re looking to protect. You might be able to blanket the surrounding area with a TRANSONIC ULTRA SOUND DEVICE. I’m sure it would cover the “air space” quite well and this could do the job. It would have to be protected from direct rain but we have had people use it on covered decks and patios effectively. And it works great for inside applications like attics and crawl spaces so don’t rule this out. It will want to run continuously by default but if you leave it running via an electric timer when no one is home or in the area, the squirrels will surely learn to avoid the area. They just don’t like this sound but people can hear it too so the deck probably wouldn’t be the place to be when the unit was turned on. Of course, the squirrels won’t be active at this time anyway with people out and about so it should be Ok to keep off for awhile without them instantly coming around.
