I wouldn't be using a power on my snake that it would be breathing in. especially not in a pillow case where the chances of inhalation the power as you douse the animal is very high. to each there own. but i know if i wouldn't want to inhale it then why would my snake?

not to mention according to this site the Hartz flea and tick powers is a rather large irritant http://www.drugs.com/vet/hartz-advan...-for-dogs.html

lots of warnings. it only lasts 7 days as well so once the new eggs hatch your back to square one powdering all your snakes. sounds like allot of work for something thats not technically designed for the use people are recommending in here. its like saying "use a hammer to open your can of beans. i know its not meant for it but ive been using it for years and it has always worked for me."
