Or, pincher bugs, if you prefer that term. I found an old strawberry pouch I'd hung up last year and forgot about, so there was this green plastic bag o' dirt and dead strawberry leaves hanging on a back fence post. Aha! I bet that would make good dust bath dirt! Carried it over to the communal dust bathing spot of last year's potting soil, up-ended the bag, and shook it out. The dirt did NOT fall out, but a zillion earwigs did. I HATE THOSE THINGS! I flung the bag away and jumped back, in that order. The earwigs were all running every which way. Buh BAWK! To the rescue came one hen, then another, then two more. Even the banty cochin scurried up. In the space of five minutes, there wasn't another earwig to be seen. So I went and picked up the green, plastic grow bag of dirt I'd tossed a few feet away (holding it with my arm outstretched) and brought it back to the scene of the melee to shake it out one more time. (And then I dropped it just a few inches away from the furthest "out" chicken.) More earwigs. VERY happy chickens. Even the rooster let himself eat a few. Earwigs all gone.
