Odd piles of red dust appearing

looks like chipboard dust from the piece of furniture you just moved. Is it just in that corner? If you rub your fingers down the rough edges of that furniture do you get dust from it, or is it wet? Maybe move it away from the wall or move it somewhere else and see if the dust moves or stays.

I think lardarse could be right. Hoover under the rim at the back of the chipboard furniture and see what happens after a few weeks. Move it to another part of the room and see if the dust follows it. If the dust moves then you have found your culprit. Cheaper than ripping of skirting boards.

Clean it up. Leave the light on and set-up a live-stream webcam. We can watch it in shifts - sure we've feck all else to be doing nowadays.

Could it be that there was insulated plasterboard fitted to the walls, like 75mm+ insulation, and when the guy was doing to flooring he just swept all the dust from cutting the laminate boards in under the insulated plasterboard before refitting the skirting, would somebody be lazy enough to do that?

Couldn't be this lad could it....

Could well be draught, opening doors or the bad wind we had where it's pushed out.

OP, it might be sprayed insulation coming out. It might be under the floor or in cavities in walls. Something like this:

I once had a wasp nest in the wall. Another time a bird nest and the small bird died and hundreds flies appeared suddenly in my bedroom. It was all in cavities in the wall.

You can open a box for an electric meter and check what insulation is in wall cavities. It should be visible there.

One thing we know for sure is that is must be very light or it wouldn't end up on the top of the skirting board.

100% timber dust. Must be coming in from under the skirting.

No, definitely not from ceiling or from above. Just updated.

We replaced all doors, skirting etc in our house and put down Almost identical floors to those, and in my view, what you’re finding is sawdust from both.

If the wood was cut inside, the sawdust goes everywhere and if there was a few deposits not cleaned up, it’ll get blown around.

People have done insurance for less.

What's sad is I though of that yesterday and was hugely excited by it.

I noticed evidence of woodworm activity in my attic while having downlighters fitted in December. It was mostly in the ceiling joists and on some cross stays, not much on the rafters. It was widespread however. I got a Dublin based company to assess and carry out treatment. I had to remove all the fibre glass insulation, an awful job. I am not confident that the treatment was a thorough job however.
Two chaps arrived, one mixed the solution in 25l drums and tended the pump. The second young chap sprayed the attic timbers.
My first concern is the ratio of the spray solution used. The label on the container I found left behind, Lignum pro D156 says 1: 24 prevention and 2:24 curative. This was mixed 1:24.
My other concern is the time the young guy spent in the attic, just over one hour. No check was carried out afterwards.
I now need to reinsulate the attic but fear the issue may not be resolved after this considerable cost, especially what's under the insulation.
The company says all is well, ratios are correct and will forward my a guarantee. Don't know what to do next.

The reason they sprayed the mix for prevention is the woodworm holes indicate that the larvae has hatched already.
So in spraying for prevention they are stopping the spread of the infection.
Spraying it at curative rate would kill any exciting larvae but the reality is the damage is already done by them.
Preventive spraying would be more beneficial in the long term.

You have the label so contact the manufacturer, give then an idea of the size of the roof space and ask them if they think that treatment would be adequate.

Thanks to both of you for your very helpful responses. My mind is more at ease.
