Dermestids / Cleaner Crews

Sorry about that Crystal - pictures would be great! = )

I'd say the red beetles were likely adult mealworm beetles (Tenebrio molitor); it isn't that uncommon to see the occasional red specimen that is hypopigmented. So yes, most likely your adult flour/darkling beetles. If you can get pictures up, we can definitely be confident.

Was tough to get good pics at 1st as they kept running around on cardboard trying to hide. Some of them were a darker red, like a burgundy maybe offspring of the tomato red ones, dunno. So I gathered them and some worms from cricket bin and roach bin plus my surplus cup and put them in this tiny plastic cup. It used to hold jack daniel's bbq sauce from sat night's leftovers.


One of the beetles decided to use his wings so I whacked him back down into cup with camera lens. You can see he still had them out and was buzzing around for a bit: He's since put them back but I can see that he has them overhanging his bum. The only one old enough to be able to use his wings, I guess.

So if these are mini meal worm beetles, (those worms never get much bigger than pictured), aren't they basically useless? All they'd do is eat the food meant for bugs and procreate. I gave them an exoskeleton and a half and they're just trying to burrow into it for cover, plus a cricket orange cube and some oats. Plan to watch and see what they do. Creepy little buggers.

Would they be a safe feeder for my toad, to get rid of them? I know their shells are hard, but I'd think outside, he (or she) would be eating things like this. So I'm wondering if I can offer them to him. Or her.

Here are some pics of my roaches, just because. I guess it's true that 1st time pregnancies can take 6 weeks, cuz yesterday was 28 days after I spotted 1st ootheca. Oh well.
She's like "are you kidding me?" But Mouse was just watching the others and she doesn't eat bugs anyway, just mews at me and paws them:Good looking fella:
This is a toilet paper tube, and a community meeting spot, I guess: and the other side.

These all look like darkling beetles to me, either Tenebrio molitor or Tenebrio obscurus. The easier way for you to make a quick reference to tell if you have dermestid beetles is by the tips of the antennae; your dermestids will have what appear to be little clubs while darkling beetles have very thin uniform antennae.

Personally, I've never heard of using mealworms as a cleanup crew. I'd imagine they'd simply use the same resources as the roaches like you suggest. Dermestids may nibble on old scraps and moisture sources, but mealworms will be feeding almost exclusively on the same stuff as the roaches. I could maybe see them being useful in bins that have a lot of food debris scattered throughout the entire bin, making things smellier and increasing the odds of flies and whatnot setting up residence, but I've never actually used them. I think Dermestids, isopods, and springtails are the best cleaner crews you'll ever find for most purposes.

The beetles are "okay" to feed to some herps - and beetles have an important role as a food source in nature for many species, but they are very heavily scleritized and can be a burden on the animal as a result of all of that armor. I would only feed them to a larger herp who could readily crush them up; they are certainly an impaction risk in smaller frog species who will fare better feeding on the larvae.

Dunno why I only sometimes get email notifications. Anyhow, that's what I figured. I worry enough about him eating meal worms, not comfortable feeding him a beetle, even if it's little.
Have a total of 3 regular darkling beetles in beetle bin as of today. Woke up and one was already out and I watched one break free of it's casing. So neat. Then a few hours later, another was out and wiggling it's legs. They're stupid and keep flipping onto their backs. Hope they get the hang of it so they mate. Hard to mate or eat when you can't even turn yourself over. Or so I've found.
Thanks for your help!

I have had success calming down odor by using FeederSource's Odor Control, a synthetic soil consisting mostly of very finely ground charcoal and vermiculite; about the size of ground coffee. Substance is spread on the bottom of the roach bin. It also makes the Pill Bugs happy while they scurry to eat the frass. I believe the Derestids will thrive in this environment and work with the Pill Bugs to eliminate stink. Feeder Source

I know this thread is a bit old but I saw a few unanswered questions and of course I cultivate and offer For Sale Roach Bin Cleaner Crews. In these "Cleaner Crews" I offer two forms of larvae and two types of beetles from two species. The first species is indeed dermistidae. The second species are a special form of mealworm that is tinier than common ones and hard to Find. Now, the Dermestid Beetles & Larvae Eat Flesh from only the dead roaches or crickets. The mealworm larvae and their adult stage beetles will eat the excess grains before they turn moldy and become a danger to your roach or cricket colony. They do not compete or take food away from your roaches as they are mainly out of the way and eating stray foodstuffs Because of the life cycle of these larvae and beetles there will always be more larvae than adult beetles as the beetles only live a few weeks and lay eggs. It is the larval form that does most of the eating flesh and excess grain. You will notice between 10-15 times more wriggling larvae than beetles.

My stock of Dermestid and Roach Bin Cleaner Crews are free from invasive species such as mites, red flour beetles or red leg ham beetles which can cause your cleaner crews or dermestids especially to falter as they are outcompeted and eggs are destroyed.

The beetles are safe to use as occasional feeders and as Jeff said not as much for smaller species. However as stated prior these species most often exist iun their larval form which is either a tiny mealworm or a tiny soft larvae, that is useful for stimulating frogs to prey on future live feeders.
