I think I know what the concensus will be, but I figure I might as well ask. We have thousands or crawlers in our yard, I don't spray for anything. Is it safe and/or healthy to feed Mikko nightcrawlers? I catch them for fishing. I have NOT fed him any yet, but thought I'd ask. Our crickets are dropping like flies, can't keep them alive in the cricket keeper, they turn over and start twitching within a few days.
