They Nest (2000)

After freezing up under pressure in the emergency room, Dr. Cahill decides to spend a few months unwinding on a little Maine island where he immediately gets off on the wrong foot with the locals. Meanwhile, a body has washed up on shore infested with a strange type of carnivorous cockroach. But when Dr. Cahill tries to warn the townsfolk of the danger, they are naturally skeptical. Will they realize the truth before it’s too late?
