The message
from Stuart contains these words:

I take it ,by the fact that you havent't mentioned it,that you don't
have a cat
..Has there ever been a cat in the flat ..Flea eggs can rest dormant
in carpets
and behind skirtings until CH gets switched on during cooler times and
they then
come alive and can bite like buggery .

And can lurk for months at the least, sometimes more.
