Hah! They say that with these, you don't NEED to clean bug bins. Poop gathers, but I think the bugs lay their eggs in it. They sort of tear apart pieces of egg crate too, just little bits, like fluff. I got them from my roach people, West Coast Roaches. They're in NC (oh hey so are you!) so dunno why they call themselves west coast... their old website with info is Live Dubia Roaches WestCoastRoaches Live Dubia Roach Reptile feeder insects and supplies and weirdly there are still payment links there. But their new storefront is Cleaner Crew. The prices and selection are all wonky. I thought they'd phased out the old site completely, and I know they're doing most of their business on facebook now, in the form of auctions. Their main page is https://www.facebook.com/westcoastroaches but they're starting to do auctions in a group (starting all kinds of things lately) https://www.facebook.com/groups/West...rsandSupplies/ Some people who have bought them say they see nothing, that they must be dead, but mine have multiplied. I left a post on their page asking about it. If I knew what exactly I have, I'd send some to you. I know they're harmless to the bugs. But I'm not sure what they DO exactly. I don't see anything furry looking like a dermestid, just beetles and teeny meal worms. Some of the beetles were red, so I'm wondering if they are flour beetles. Neither the beetles nor the larva can climb out of containers, and none fly, so not worried about them getting everywhere.
Regardless, my crickets have never had the offensive odor people talk about (but I never have hundreds or thousands at a time), and dubia roaches just plain don't smell very much.
If I can figure out what they are and if they're actually doing some good, I'd be more than happy to send some to you. Cuz right now, I just don't know what to do with them.
