I am done.
I'm about to just lie down and surrender my bodies to the fleas, they have won, I have lost.
I fostered a mum cat and she had five kittens in my care. I was informed that she definitely didn't have fleas but low and behold of course she did. By the time I had noticed the house was lifting with them 
I treated all my cats three weeks ago and sprayed the house, washing soft furnishings etc. Hoovered every day like a good girl, but the fleas just kept seeming to multiply.
The cats were adopted so we sprayed the house again and went on holiday for 5 days. When we came back the cat room was like a flea rave, I walked across the room and they were bold as brass swarming around my feet and legs. I sprayed the room again, cried, had a tantrum and single handily lifted my carpet and removed it from my house. Then I sprayed the room again.
I can still see fleas merrily jumping around my cat like it's Saturday night at flea Glastonbury.
Today I am re washing my sheets and spraying my poor naked house again.
Please say there's other people in the same boat, I need a hand hold... and a bath.
