If you have a garden of any type, you need to worry. We are absolutely over run with earwigs this year. Anytime a rose blooms, it looks like swiss cheese within a day or so. I had a healthy milkweed plant one day, the next it had been eaten down to the stalks. They did so much damage to it, the plant died. They have eaten almost all of my seedlings, I moved the survivors to the house, not realizing they are in my house too! This is the absolute worst I have seen them, there are to many for my hens to keep up! I am picking up some food grade DE at the feed store today to use around the yard where my hens aren't able to get to. I can't stand those buggers. Every time I move something now, I found one or ten! They are pests to your garden, but as the others have been saying, snacks for your babies!
