It's by Lucky Reptile and called Bye Bye Mites.
I read all the instructions on it and seems to be available widely in the UK and it was all my reptile store had (we don't get Provent a Mite in the UK).
It says to spray the snake and the enclosure - so I took out snake and put her in the bath, then removed all the substrate and binned it - cleaned viv thoroughly with soap and water, then sprayed this stuff all over it and left it to dry. Meanwhile I sprayed the snake (making sure her eyes were protected, so I guess it never actually got on her head at all - just the rest of her).
When viv was dry (smells like anything of this chemical or whatever) I rubbed it over with paper towel and put in newspapers and paper towels for substrate.
Reintroduced snake and cleaned disinfected and Bye Bye Mites sprayed water bowel and hides.
But it smells like anything, she was trying to get out - I'm not sure as the chemicals might be bad for her or anything. When she did decide to rest inside her hide she kept her head out. I felt sorry for her so she's out now with me while I keep the viv doors open for a while.
Should I have re-cleaned it after the spray (it doesn't say so on the bottle) to get rid of the smell?
