RE: mites Reply by bush_viper17 on February 8, 2005 Mail this to a friend! Ive done this so far. I sprayed him with Mite Off by Zoo Med. I waited for about 3 days then soaked her in water. I noticed that alot of dead and alive mites came off of her. I then inspected the cage and saw mites everywhere so i changed the snakes water and let her soak again. I put her in a new container and sprayed the cage with a bleach/water solution. I let the cage sit over night, Later today Im going to spray the cage one more time. The snake looks like it is about to shed so I think Ill wait until it sheds and put it back into its old enclosure. Does that sound like it might work?"

I picked up a can of P.A.M. for $30 at a reptile expo and have no idea if it is a good or bad price but have to say, I do not feel ripped off even if it is usually only $15 a can.
Worked out over how long a can lasts for me it is still a tiny investment.
The biggest single drawback to P.A.M. is it isn't available at every major departments store and pet store.
This is actually something that is going in "reptile gift baskets" from now on. If I set a kid up with a reptile and habitat, A can of this stuff is going to be included.
Hope that help.
