“Our new cart-mounted Rascal Eradicator uses carbon monoxide to kill gophers, prairie dogs and other burrowing rodents quickly and safely. It’s simple, safe to use, and works fast,” says Bill Enderson, Fort Lupton, Colo. 
    The 4-wheeled machine rides on 10-in. pneumatic tires and is about the size of a red wagon. The cart comes with a big, adjustable U-shaped handle on one end and a hose rack on the other.
    The unit comes with two 25-ft. long hoses and uses an easy-start Briggs & Stratton 4-cycle gas engine. You just place the hose into the open hole, pack soil around the opening to seal the burrow, and start the engine. The carbon monoxide that’s produced quietly puts the animal to sleep as it fills the burrow.
    “It doesn’t use poisons that can kill other animals and pets, and it doesn’t cause explosions that can disturb large areas of land,” says Enderson. “The carbon monoxide goes directly into a patented resonance chamber where it cools off before entering the hoses, and the volume of sound is reduced so it runs quiet. We call it the ‘cool, calm carbon monoxide delivery system’.”
    The cart makes it easy to move from hole to hole, he says, and with both hoses you can easily cover a 50-ft. radius. He recommends running the engine for 7 to 10 min. per hole. “Using both hoses at the same time doubles the efficiency,” says Enderson.
    He says the machine has been field-tested for more than 2 years and is almost overenegineered. “We know from experience what’s out there, and we want our machine to last for our customers. We figure it costs less than $3 per hour to operate.”
    Options include a 50-ft. hose, specialized nozzles for different burrow types, and a hitch designed to pull the cart behind an ATV.
