[Vectis Hamstery]

I would recommend seeing your vet for some appropriate spot on treatment for your hamster. I've used Stronghold on my hamsters (which was prescribed for them). You would need to do a thorough clean. When I had creepy crawlies on my hamsters all the wooden items went in the bin and everything was disinfected. I also used bug bombs in the room (after taking out the hamsters of course).
