Killing bugs can result in more than one downside for those with a sensitive constitution. For one, you kill a poor, helpless bug. Secondly, you leave said helpless bug's entrails smeared all over your wall, necessitating a cleanup, which is downright annoying.
The Bug Trapper solves both of these problems. Simply trap the bug, flip the trapper over to close the door, and release the bug safely outside (or in the toilet, if you're only worried about problem 2). It's a simple and elegant way to dispose of pesky insects, albeit kind of a pricey one at $8.
