Some of those suckers are smart. Had one or more get past the ambush I set up with sticky traps and a dog treat. Had to use more traps and fix it so the only way they could get to the treat was through a sticky trap. That is when I started catching the adults.
They're also fast; I've seen them run across glue traps and not get caught.
I've also seen one manage to extract himself despite being glued down by body hair and head, not just feet. I figure it just wasn't that one's day to die.
