Rats have been tormenting mankind since pretty much forever. They do untold damage. They spread disease and consume a staggering amount of our food. No matter what humans have thrown at them, they have displayed amazing resiliency, and thrived.
Now the EPA has decided to regulate and outlaw rat poisons for various reasons, including accidental child poisonings and damage to wildlife. See: EPA bans Decon
I would happily get behind any method of rat control that didn't involve poison. Besides being dangerous to kitties and dogs, it is expensive, and only partially effective.
However, the EPA's suggested substitutes are absurd. Close up all cracks and crevices on farms. Yeah, okay, our barn is over 200 years old, 120 feet long, and that's just one section, two huge stories tall and has doors, stable cleaner chutes, which can in no possible way be secured and still function, dozens of windows, etc. We keep our grain in a steel augur bin, but inevitably the cows spill some.......And that is just ONE of our many buildings.
Use snap traps. Yeah, there's a plan. If the EPA will come in and set them for me and take the dead rats out I am all for it.
I don't think they will though.
