+1 I've seen them sold on ebay as a "dubia cleaning crew". They eat up all the dead feeders so you don't have to remove them. I don't know if, over time, they may become over abundant in the bin or not.
Dermestid Beetle larva
Yes, they are dermestid larvae. These beetles are beneficial in the sense that they will eat dead feeders, keeping the colony clean. They are also used in taxidermy to deflesh animal skeletons while keeping ligaments intact. It is important to contain them, since they will eat almost anything organic, from rugs to clothing, stuffed animals, etc.
They clean up your dubia's? I want them NOW. How do I find them?
Maybe I don't want them. Are these the same beetles that they put things like a elk or deer, heads in to strip it for mounting? David would never let those near the house, and they would scare me to death.
Yes, they are also known as "flesh eaters" for this exact reason. They are no threat to you or your animals. Not even to your feeders you maybe raiseing. The big farms that raise crickets use these beetles to cut down on waste and ammonia build up, that is why sometimes they come in your order with crickets. They only eat decaying/dead material similar to maggots. The beetles can fly ( atleast mine did) but are not very good at it. Very slow also. They are an excellent food source for hatchlings. My bearded dragon hachlings loved the larvae and beetles. Thats mainly what I used, which saved me a bunch when it came to feeder costs.
Also they make breeding crickets MUCH EASIER from my experince. I had alot less deaths due to them. Crickets are very fragile little things ,and can die from the smallest raise in ammonia.
I dont think there is much risk of them infesting ( unless they are a native species). I had some for a while, and they always escaped. After I stoped feeding them, they all died, and so did the escapees, but took longer for them.
Dermestid Beetle larva
Great posts, good tip for the dubia colonies! Thank you.
Gonna go fishing in my cricket bin right now for these. I've often wondered what they were.
Are there anything harmful about this in the home? Do they fly? Will they eat natural fibers in clothes?
