Bugs in Repti Bark?

[bsd13]

Well I decided to swift threw the repti bark. He pooped two days ago in his hide and the pee from it must of went down to the bottom of the tank cause I found a whole lot more of white bugs and now black bugs same size.

I've managed to buy more than my share of bug infested bedding, especially repti-bark. I figure it comes with the territory. First few times I made an issue out of it but it got to be too much of a hassle trying to get my money back. Now I either bake it, or dump it and stick with newspaper and/or paper towels.
