How can I keep earthworms off my porch?
I have a lovely three-season porch surrounded by a boardwalk. Two of the walls are sliding glass doors (3 doors make one wall, 2 doors the other) and the other two walls are the outside of my house. The floor is porcelain tile over concrete. Whenever we have a heavy rain, I find unwelcome earthworms on the porch. I can only guess they are coming up through the drain holes in the door rails.
My question: Does anyone know of a way to discourage these little creatures from crawling onto my tile floor? Currently, I let them dry up, then I scrape them off with with a putty knife. (Yuck!)
Thanks for your ideas! -- Kathy
