I have a wonderful raised veggie bed. This is the first year in 10 years that I've had a problem. I've planted kale, chili peppers, cilantro, and now cabbage. Everything has been eaten over night. Like it was never there. I've gone out at night hoping to find something. I've put down sluggo to no avail. I wrapped the bed in chicken wire. I've put copper tape around the perimeter. And still whatever it is is eating whatever I plant. Does anyone have any idea what it could be? I have now put nematodes in. Because I have found some little white rolls polly looking bugs in the soil. Now I'm inspecting the soil. This is beyond frustrating!! any ideas??
Although it's often said that pillbugs (AKA rollypollies) are harmless, they will mow down seedlings, sometimes, especially if there's a lot of uncomposted organic matter near them. To stop them from doing this, just pick up all the pillbugs and put them somewhere else. Then, remove all the uncomposted organic matter from around the seedlings (so as not to attract new pillbugs). They shouldn't bother your plants after that.
Other possibilities are cutworms, flea beetles, rodents, rabbits, and other animals.
