Kill Underground Pests With Gas-Powered Tool
Clear out gophers, ground squirrels, prairie dogs and other tunneling pests with the gas powered Cheetah. The small engine does double duty, driving a powerful fan and producing the exhaust fumes the fan pushes into pest tunnels. Developed by Dana Shaw, Cheetah Industries, to control ground squirrels, the pest control package is catching on fast.

“When I moved to central California 4 years ago, there were ground squirrels all over the place,” explains Shaw. “I tried trapping and everything else. Eventually, I tried hooking a hose on my car’s exhaust.”

Shaw realized the exhaust carbon monoxide (CO) needed to be under more pressure to work well. To get EPA approval for rodent control, the concentration of CO has to be at or above 25 ppm for 30 seconds, which starves the brain for oxygen.

The Cheetah motor and fan produce 3,000 ppm of CO in a 100-ft. tunnel in 30 seconds. The engine exhaust enters the tunnels at 195 mph. CO at only 1,000 ppm is lethal in 15 seconds.

Shaw explains that the high CO production level is necessary because of the tendency for gopher and ground squirrel tunnels to cross connect. Regardless of how much CO is produced, once the engine is shut down, the CO is quickly diluted.

The Cheetah consists of a small 2-cyl. engine with a 450-cu. ft./min. blower. The 14-lb. Cheetah comes with a 1-gal. gas container, oil additive for 3-gal. of fuel, a flexible exhaust tube and a tool for spark plug removal. The engine is quiet and EPA approved to meet all standard emissions rules.

Shaw recommends running the engine for only 3 min. to treat up to 400 sq. ft. of burrows. For open burrow animals like ground squirrels, prairie dogs and groundhogs, the flexible exhaust tube is extended 6 in. or more into a tunnel and covered with a few inches of soil. Once the engine is running at full throttle, other entrances within 8 ft. are filled in. If air can be felt coming out of the entrance, it’s connected to the tunnel being fumigated. Larger areas may require treating multiple entrances.

Shaw sells his machine direct. “I like to talk to the customer first to be sure they need it, given its cost,” he explains.

The Cheetah is priced at $1280.00 and comes with a one-year guarantee. Shaw claims an 80 percent kill rate with a first application. Following applications can reduce populations by more than 95 percent.
