Die, Bug, Die! (The X-Files: Middle Grade, #10)

Everybody hates roaches, but at least they're harmless--except in Miller's Grove, that is, a small town with a giant roach problem. Reports of killer roach attacks are pouring into this once-peaceful village, and human corpses are piling up. Special Agents Mulder and Scully have to find out what's happening or face certain extermination--of the entire human race!
