Milk jug...I don't think I would have ever thought of that, but it makes perfect sense! Anything that makes dealing with these insects easier I am all over it! I try and get them and have them eaten before they start making all that noise-the chirping drives me nuts. I can feel a twitch coming on as I type! Sigh, the things we do for our frogs and reptiles....good thing they are more than worth it!
