There is a new reality show on the tv these days,
called "Corkscrewed: the Wrath of Grapes". In the show the two
producers of the reality show "American Idol," Nigel
Lythgoe and Ken Warwick, buy a vinyard near Paso Robles California, and
proceed to have everything go wrong with their plan to be vintners.
Their grape contracts are cancelled, the heat kills their owls, and
gophers start to take over the vinyard. The rodent disaster is saved
when an inventor from Idaho drives in to save the day. That man is Ed
Meyers, President of an Idaho company that sells a rodent control
product called the Rodenator.
The producers feel a little sorry for the furry critters for a few minutes, then when they think of the $6 million they have riding on the harvest, they are all for nuking the gophers, at which time Ed is happy to provide the pyrotechnics. Ed is shown in three episodes of the show that I have seen, and solves at least one of their many problems.
The Rodenator is a portable device which mixes oxygen and propane, and sends a swirling mixture into the rodent burrows. A spark from the device ignites the gases, and the borrows for up to 300 feet are blown up, instantly killing the gophers, ground squirrels, or other borrowing pest. The Rodenator website has more information about the device, including videos of the device in action.
