From Dusk Till Dawn's Gecko brothers (D.J. Cotrona and Zane Holtz) have their hands full this week -- in the Tuesday, September 27th episode -- as a creature called the Cipatli releases bugs that turns ordinary suburbanites into ravenous cannibals! In this exclusive clip from "Shady Glen," Seth and Richie, along with Jake Busey's Aiden and Jesse Garcia's Freddie, do house-to-house sweeps for these malicious monsters, sometimes scaring peaceful residents in the process.
