What happens if these come in contact with humans?

Nothing, they only eat dried crispy flesh so they're no harm to anything alive.

Ahh, because there are beetles all over this motel I'm in, and I have these awful bites on my legs that will just not go away. There are about 11 of them, they've swollen up,and gone really awful red and very painfully itchy. I've been wondering what decided to have my legs for dinner, but I don't know anything about beetles!

I did, they're far too big for bed bugs, and even though I sleep in the same bed, there've been no new bites at all, just the initial ones, and it doesn't go in the "breakfast, lunch & dinner" order bedbugs go in. I think it's an allergic reaction to a spider bite (my mother's allergic as well)

I have never been bitten by mine, but they are also known as Carpet Beetles, so it might be them, or something similar that is nipping you while trying to tear up the sheets or mattress. O_o

If you have a fairly steady amount of skulls/bones or just a ton to clean they are the absolute best method of cleaning, particularly with delicate specimens like birds and reptiles. There's a few places online that sell them but I got mine from the wild by baiting them with leftover food from the raptors at the center. I started out with maybe a couple dozen and it was slow and tricky in the beginning but I've had them a year now and their numbers are in the thousands. The only other problem is them and the dead things they eat have an odor most people take offence to, I have to keep them in a shed far away from where the other staff and volunteers go. But the smell is nowhere near as bad as macerating skulls. If you have anything you need cleaned and were willing to ship it to me, I could have my colony clean it possibly.
