How do earwigs get into a basement thats completely sealed off?
Earwigs are a distant relative of the cockroach family. Much like roaches, they can compress their bodies down to an almost paper thin thickness. This enables them to enter through the tiniest of places. It’s my guess that the basement you have isn’t completely sealed…it may be 99% sealed, but all they need is that tiniest spot. There’s also the possibility that they could have traveled in with something brought in from the outside. A box, your pant leg, whatever. From there, they breed and reproduce.
