The demo is slowed down for, well, demonstration purposes. The bag is optional, only needed for the hard to catch ones. I don't care how long it takes anyway (minute or so), as long it persuades them to stay off my runway/kills them!
Another exhibit at the same farm show, had another approach: a 2 stroke engine with a powerful fan, and a length of high temp flex hose. The concept was to take the exhaust and blast it down the hole at a high rate of speed. Since the exhaust is heavier then air, the tunnel will soon be deadly to it's residents. Another model was designed to work off a tractor or ATV battery and exhaust system, same concept, gas 'em!
I still use the traps, the good thing is you get the bodies, and then you can cut their heads off and mount them on popsicle sticks and stake them out around the property, this is known to be a deterrent, according to experts.
Just making that last part up, but it could happen! Actually, since getting 26" Airstreaks, it is not that big a deal as it used to be on 8:00's.
