Dead Fast Insect Control Chalk
Very easy and discreet way to keep the hordes at bay. We had ant trouble in our new house and this made it very easy to stop them from invading the kitchen without having to set traps or use poisonous sprays. It's EPA-approved, the cats ignore it, and if you have kids the packaging is childproof. Just draw a line around where the ants want to go, and if they cross it, they pick up the poison and die. The ones who don't die quickly take the poison back to the nest and spread it. Simple.
