Something has been nipping away at my kale leaves. These are growing in a raised bed and I don't see any snails around. I have also covered up the bed with a net to keep away squirrels to the extent I can but they may be getting in. Any ideas or other pests that may be enjoying my kale?
That looks like caterpillar damage to me. You can sometimes spot and remove the caterpillars at night, or else a spray with Bt (Safer brand "caterpillar spray") is a safe and organic way to kill them.
