Escapees!

These little buggers really know the art of escape! I still don't know how they did it. The small hissers seems always find their way out somehow. The most surprising is adult giant burrowing roaches, not sure whether they climb out from the small gaps between the cover and the bin, or they fly out through the small gap I left in the cover for ventilation, but that would require some precision flying since there is absolutely nothing for them to cling on anywhere near the gap which is only 1/2 wide, and 2 feet off the ground.
