The managers will make me pay anyway and probably blame me in the process and try to make me pay for everyone else in the process. I'm like 90% sure it's bedbugs I have compared pictures with the actual bug. I am using food-grade DE, although it may not be healthy, it sounds like you used pool-grade DE. This is going slightly off topic. Does anyone have experience in seeing their (or an associate) reptile attacked by bedbug?
