The Internet Has a Rat Poison Problem
I use the old-fashioned snap traps. They work fine. Sometimes it's necessary to tweak the catch to make it more sensitive. They're made of wood and wire, and aren't an environmental problem.<p>I live near a greenbelt and there's a never-ending invasion of mice. If I leave the garage door open and unattended, they're in in a flash and setting up shop. The only way to get rid of them is the traps, and you have to get rid of them.<p>Peanut butter bait is irresistible. I used to use gloves to bait them cuz the books say they mice are deterred by human smell. They aren't. They aren't deterred by The Cat, either, as they know The Cat prefers human flesh. They're not very smart, either, as if you put two traps adjacent, they'll crawl over the body of their buddy dead in the first one and get caught by the second.
