Itsy-bitsy eliminator

Ever wonder how to rid your home of those houseguests who just don’t get the hint? Though the new Electronic Pest Repeller by Black & Decker won’t work on family and friends who are between jobs and on your couch, it will help eliminate the peskier ones such as spiders, cockroaches and mice. Designed for those less inclined to spend hours setting traps and spreading boric acid on doorways and windows, this device emits highly powerful ultrasonic signals that disrupt pests’ nervous systems. Unable to withstand the audible disorientation, the sounds compel the unwanted to seek refuge elsewhere. Akin to a bartender at closing time, the unit basically says to these creepy-crawlies, “You don’t have to go home, but you can’t stay here.”

From $7.99 to $19.99 at most home centers. (800) 330-4108, www.blackanddecker.com.
