Thanks so much for the info girls. Mrs Mac, I think you are right about the insect plague at the moment!
We have floor boards (no carpets) which is great as we dont have the flea problem and even though we have 2 dogs, neither have had a flea in about a year and a half. I am always checking them.
Tattoomama- thanks for the heads up on the spray that doesnt stink like fly spray. I might make a trip to the supermarket today.
Snacks- I will give the landlords a call today. Unfortunately they property manage themselves so I always feel awkward about asking stuff to be done as I have to do it directly. thanks for your advice.
