How an empty flat fills with fleas
Eggs a previous pet left behind in the carpet hatch into larvae, which then pupate inside a tough cocoon capable of lying dormant for weeks once the property is empty and undisturbed, just as near Stanmore, where larger 1930s houses and gardens towards the edge of the borough near the Green. Body heat and movement are what trigger the next generation to emerge, which is why a flat empty between tenancies can start biting again within days of new furniture and people arriving, whether that's near Rayners Lane, where 1930s suburban semis built up around the tube station and shopping parade, or elsewhere in the borough.
Flats around Harrow and Wealdstone stations
The end-of-tenancy turnover around both stations means this pattern shows up regularly: a flat stands empty for a few weeks after one tenant leaves, and the next one starts getting bitten around the ankles almost as soon as they've unpacked.
Is it really fleas?
A flea bite tends to appear low down around the ankle, and unlike other insects a flea jumps instead of crawling; its droppings turn reddish when dabbed on damp paper, true near Pinner too, where classic Metroland semi-detached suburbia with a village-style high street. Bites in a row higher up point somewhere else - the Harrow bed bug guide covers that instead.
If you have just moved in
Keep track of when the bites started and where, and photograph any flea dirt you find in the carpet - the same pattern holds near Kenton, where interwar semis shared between Harrow and neighbouring Brent. Get it in writing to the landlord, agent or seller as soon as you can, that way there's a record of the timing, whether that's near Pinner, where classic Metroland semi-detached suburbia with a village-style high street, or elsewhere in the borough.
Clearing the carpets
- Pull furniture away from the walls so every edge of each room can be reached
- Vacuum thoroughly and empty it straight into an outside bin, not an indoor one
- Wash any pet bedding on a hot cycle
- Keep using and vacuuming the rooms after treatment rather than shutting them up
