Larva of a larder beetle

6286 Have no clue what these things are, its like the larva shed their skins and turn into these black nightmarish things. I hope they aren’t bad for my health or my dogs’ health, I’ll do anything to get rid of them. The larva has spikey looking hair on them and these pronged horns on the back and when they grow up their bigger and their tails are longer, they do look like they bite but I’m not sure yet. They have six legs though all together. From Calgary Alberta
