It quickly abrades their exoskeleton, especially at the joints causing them to essentially bleed out moisture dehydrating and die and they can't clean it off.
If other bugs find the nest to try and recolonize it, they will not live long enough to move in, and when they go back to tell their friends about the nest, they bring some back and introduce it to their friends.
Like I said, not as much fun but quick and 100% effective!
