I have a new problem. I have a worm condo that has been doing pretty well for awhile now. Lately, I've been seeing these short (about an inch long) black bugs with no legs wiggling across the patio. Lo and Behold when I just opened my bin to put in more watermelon rinds, I find the top bin is FULL of these guys in all sizes from tiny to huge!!! What are these, do I need to get rid of them? Do they eat my worms? ACK.
