I've now come to the conclusion that my worm bin revolt problem was not in fact due to environmental issues but rather my lack of attention in feeding them on a regular basis. At one time the worm bin was located in my kitchen which made it easy and convenient to feed them. But since I relocated the bin to the basement, I admit I have been lazy and not attending to them as much as I should have. Yes, I am a cruel worm owner. Please don't tell PETA!
I've had this latest herd of Red Wriggler composting worms for about a year but really haven't been keeping up with their health and safety. Basically I had been feeding them and then forgetting about them for long periods of time.
