I've had my colony of Blaptica dubia for 3 years to breed for my lziards, and a few months ago I fed my beardies heavily with the roaches, so I didn't have enough to spare for the girls I recently got. But after an explosion of babies due to the heat I have a few thousand, so lately my girls have been getting several roaches per day, and I can say I've never seen them happier to see me. Unlike the pest roaches, Blaptica dubia does not climb smooth surfaces, is slow moving, can't fly, won't bite, doesn't smell, and won't breed when kept under 80 degrees. Another upside, they are good sized. About 2-3 inches when full grown and unlike mealworms or crickets, they are PACKED with protein. Over 30% per adult roach. They breed fast once a colony gets going. I don't know why I didn't think of it sooner to feed the girls these! And no, these aren't for the squemish. But I can say I do enjoy checking in with the colonies progress every few days, sometimes I even hold the calm "little" guys. And if I've finally convinced you, visit TheRoachGuy.com. He sells these roaches at the best price, and can supply you with everything you need. You just need a bin. (Oh and he even ships to Florida!) When I take the egg cartons out for cleaning, I can say there's a good 3 inches of roaches on the bottom. I feed them anything, but the roach chow from the site is the staple.
