Earwig Trap, I finally found an easy, cheap, natural way of getting rid of the pesky earwigs that have been eating all my flowers & veggies. Use a low-sided can, such as tuna fish can and fill 1/3 full of vegetable oil. Place the can where the earwigs are a problem. The oil attracts them and it doesn't allow them to crawl back out and they drowned. Give it a few days and you'll be amazed at how many dead earwigs are in the can. It's better than using chemicals!
