The hot pepper wax sound good. Thanks, Betty. It's nice to hear of somebody's actual experience.
Liquid Fence doesn't make anything for raccoons and possums. Ducks, yes, armadillos, yes, horses, yes. But the most common invaders? No.
Rapparee, the deer blood might attract them, esp. the possums, which I understand will eat anything. Possums might think there is a dead or injured animal to eat.
It's a built up area, and shooting is out of the question.
