I just recently found a giant red headed centipede and have made a home for it out of a 2.5 gallon water jug I bought at walmart. It's clear with a slight blue tint. The number on the bottom is 1. Now this type of plastic is apparently releases toxic chemicals if heated. I wondering if anyone else has used this type of plastic for their jugs and if they have had any problems? I'm sure the centipede is fine for now, not using a under tank heater currently due to warm temperature. But this fall and winter I'm worried I may have a problem if I continue to use it. Any help or advice would be much appreciated! thanks everyone!
