Guys, I said this earlier, and I'm serious. It works. If you want to use poison to nuke rodents, you can get away with using coke. Regular stuff, not the diet, and I pretty much stick to the name brand.
Get a two-litre bottle, pour it out in a shallow pan around dusk, stick it in the shed, and walk away.
They seem to like drinking it, but since they can't burp, they end up hemmorhaging. And if pets find 'em, and munch 'em, no problem.
