I have:

1)
Little mite type things on a couple of window ledges, they are kind of
like a wood louse shape, 1-2mm long, say .5mm wide, two longish antennea
type things and at least fine 6 legs. Brownish in colour.

They don't look like any furniture beetle / woodworm I have seen. They
don't crunch when crushed but splat and occasionally jump out of the way
of an impending finger nail.

They are more prevalent outside the windows and appear to be getting in
through slightly imperfect seals (even on a 2 yr old DG soft wood window).

There are no flight holes etc (even in an unfinished ply sill) and they
don't appear to be venturing far from the window.

Seen them off and on for a while but lots more over the last few weeks.

2)

Found several "worm like things", black say 2mm wide by upto 20mm long
at the edge of my carpet, in close proximity to an external door. By the
time I find them they appear to have died and dried up. They have
sharper "ends" than an earth worm. Not found any since say April.

For 2) The room in question is partially tanked with delta membrane and
has land drain below DPC, EPS insulation and concrete floor.

Any ideas what they are? Eradication info?

TIA,

Alex.
