How large a crack can a cockroach crawl through?

on

Published in Daily Trivia

Young cockroaches need only a crack as thin as a dime (about .5mm wide) to crawl into. Adult males can squeeze into a space of 1.6mm or the thickness of a quarter. Pregnant females need the most space to hide: 4.5mm or a space as tall as two stacked nickels.
