My dad taught me another trick with ants: Fire ants are territorial. If you have more than one hill, grab your shovel and scoop part of one mound and put it on the other, then do the same with the second mound. They will kill each other.
My friend's bald husband taught me a great shaving trick, too: First, get a really good men's razor with the blades you can change out. Keep a cup (like a coffee cup) in the shower, and keep enough alcohol in it to keep the blade submerged. (You'll have to top it off every so often.) When you shower or bathe, don't use soap at all--just the alcohol-soaked razor. I was scared to death to try it the first time, but I've never had a hint of razor burn, and it's the closest shave I've ever had. The alcohol keeps the blades sharp and rust-free, and soap/shaving lotion/etc clogs up the blades, too.
BB--I love these. A local guy writes these tips in our paper every week and they fascinate me!
