I wouldn't know where to start. Earwigs creep me out. My Goliath is a good softball size and he's way past the earwig stage. He's more into the bait shop nightcrawlers. What a chubby!

A woman I know lays old rugs or rags in the clefts of tree trunks. They seem to love it under there & every so often lifts the rug & shakes the earwigs into a coffee can to feed her chickens. That works really well for her. Hundreds of 'em!

there is a special spot in heaven for someone who will cultivate earwigs because their toad likes them. :) Let us know what you try!
