I moved recently and ever since I have been bitten frequently in what I am fairly sure are flea bites. I have no pets, though the previous owners did. I don't have carpets either so I don't know where they are hiding. I have tried Indorex and vacuuming. removing the bag frequently. I am still getting bitten most days. The thing is I haven't actually seen any of them but what else can it be? out of desperation I called rentokil and was told as I haven't seen any fleas they won't treat. What do I do now? It can't be bedbugs as I have bought a brand new mattress.
