Even if they are safe, so many areas spray serious pesticides to control them you might not be able to find any that aren't coated with something toxic. I'd just avoid them entirely. So many other better feeders available.during the warmer months there seems to be an abundance of gypsy moth cocoons in trees loaded with caterpillars. Has anyone ever fed them to your chameleons? They are pretty fuzzy, don't know if that is good or bad?
