Okay, I'll agree that BBS are easy, except you have to restart the "culture" every couple days. I have found that a little bit of rotting leaves or sphagnum peat in the bottom of a wading pool, bucket, or anything in between will draw misquitos, who start the culture all by themselves, and renew it every day. How much easier than that do you want? Okay, so ambient temperature has to be within a certain range, but here in Boise, that gives me from April to October, most years. I also think that microworms are easier than brine shrimp. Just start a new culture every month, and harvest the old one until it crashes. Bob Dixon
