I've never heard of a male ham going crazy because it wanted to mate unless theirs a female very close by so I doubt very much that has anything to do with it.
Can't say I've ever heard of sprays being used on hamsters before either, do you know what it is?
He might just have been upset due the house cleaning, the can get quite agitated by cleaning so it might be an idea to try to get him to use a litter tray with some sand in, either close by his nest or if he has a big house inside so you don't have to destroy the nest when you spot clean.
