Last year I thought there was a squirrel taking one bite out of every strawberry, pepper, and tomato in our garden. This year, I have discovered that at least with the strawberries, it wasn't a squirrel at all. It was slugs, eating one hole, about a quarter of an inch deep and a quarter to a half inch wide, in each one of our strawberries. I caught the culprits in the act. But they are mostly not a problem right now. I think the mockingbird that likes to hang out in the tree near the garden containers has eaten the slugs.
