Nothing like that as far as I know. And my family generally doesnt go into the snake room, so i doubt one of them would have had any reason to clean or spray anything there. We painted my sisters room which is down the hall about a year ago but left the snake room door closed and the window open the whole time to make sure it didnt get to them. The only cleaning solution i use for the cages is a diluted chlorhexidine solution or anti-bacterial soap
