Came back from 3 weeks holiday in August to find cat had fleas. Cat lives mostly in our kitchen-diner. Did full de-fleaing process for cat, super-strength sprays of floors, skirting boards, cupboards etc. (twice), washed everyone, hoovered endlessly. Apart from rug, no soft fabrics/carpet/curtains in dining area, just usual hard furniture.
But sitting at the kitchen table, something is making both DH and I itch. Not happening anywhere else in the house.
What have I missed? What should I do?
