“I have an infestation in my condominiums in Henderson, Nevada”, writes Jennifer in her submission regarding the mass of black, worm-like critters pictured below. “They are parasites and live in the walls, under sinks, even the toilet tank. I’ve been spraying and cleaning everything, and it keeps it bearable, but never gone. I recently found a spider in my front door area, and I think there is a nest of some sort right outside of my house. Please help me if you can.” Right off the bat, we have to say that we will only provide suggestions for the creatures’ identities under the assumption that they are not parasites.
