I live in a neighborhood with a ton of trees. It's actually one of the reasons we wanted this neighborhood rather than one where the builder just bull dozed every tree in sight. But with the trees comes the squirrels. They never bothered me before but they sure are now. Just when my lawn is looking lush I now have to deal with the craters the squirrels are digging up. I've found a number of products that claim to be effective and non-toxic but I'm wondering if any of you have had any success with them. The products I'm looking at are: Shake-Away; I Must Garden, Messina Wildlife Squirrel Stopper and Critter Repellent. Has anyone tried these and did they work? If not, what has worked? What about the electronic repellents? Any insight is great appreciated.
