Hi Jill
Nice to have you with us...I'm in Spring Hill, north of Tampa.
I know of many folkls who've had problems with the squirrels and I'm not sure anybody has come up with a sure-fire way of fixing the problem.
There are pepper sprays available...some people swear they work and others see no results. I've heard of people having success with moth balls, maybe you can try them.
Somebody in our club saw a kit online to get rid of squirrels from their gardens and thought it was a great idea so they bought it. When it arrived, it was a few little mesh bags and about 6 mothballs...2 per bag
Much cheaper to buy a box yourself and tie them up, huh?
Our other members are sure to post some more info for you...good luck
