Here you can see how small they are; and a lot of them are smaller still.
Although they can be found in many, if not most, houses, you’ve probably never seen one of these pseudo-scorpions. They’re very small and they stay out of the way.
But they eat bedbugs and moth larvae! Doing without the pseudo-scorpions may be a lot more trouble than it’s worth. Probably the only time you’ll see one is if it falls into your sink or bathtub and can’t get out because the porcelain’s too slippery.
If that happens, it would be the deed of a kind and generous heart to scoop the little fellow out on a sheet of toilet paper and let him someplace where he can go back to being practically invisible.
