definetely get them out immediately. you only want them to be feeders, not roomates. i used a critter keeper until recently. now i have a five gallon, hexagonal fish tank that the crickets live in. i am really liking the tank so far. i threw a few sticks in that i harvested from the woods and baked off, and the crickets love it, i think. there are a ton of options for you to house crickets, just use a little creativity and you'll be fine. take care. -matt
