Some critter is eating my strawberries. It may be more than one. It was sudden. Yesterday I went out and about 15 berries (I only have about 12-14 plants) were either completely eaten, or nibbled. Today, even more. Many were quite green. The bites look like they are from a mouse. What can I do? Is there anything (organic) other than a physical barrier? These are the best berries, and they've been gettin eaten just as soon as they ripen around here. I want some!
