...and then they trip my trap. Seriously, I think the ants, which have been my primary customers in the raccoon trap smorgasbord, and who love love love the high in protein cat kibble I use as the standard bait, tried so hard to get the cat kibble out of the little dish I use that they moved it and bumped it into the trap tripper and tripped the trap. At least, that's the only thing I can think of that would explain why the kibbles are gone but the hardened, glue-like leftover barbeque is still there. I'm willing to entertain other theories, though.
Needless to say, ants don't stay trapped in a cage that has 1"x1" holes.
