White mould mites

We have an infestation of tiny white bugs in a bedroom. They look like dust to the naked eye but can be seen moving about. They are on the walls, windows and bed headboard. They are probably on all the bedding but difficult to see. We have since washed all the bedding at 60c.

Google suggests these are white mould mites, living on mould. We have now opened the windows and intend to deep clean the room today.

A student family member spends all her time in there and doesn't normally open windows, so that is the likely cause. It doesn't look mouldy but have had issues like that in the past. It's all painted with anti-mould paint.

Anyone even heard of these or suggest remedies?

 

Struggling to get a clear photo using my phone

 

I tried Raid fly spray which didn't work.

I have this stuff used in my greenhouse once when I had red spider mites, not sure if it's safe to use indoors on a mattress?

 

I just read the label on the above and clearly it isn't for use on human bedding

 

Yes I do have a steam cleaner, which had completely slipped my mind. It has all sorts of attachments some I've never used for cleaning curtains. That's a great prompt, thanks @pete.

 

So I used the steam cleaner on the bedding and windows, sills, blinds etc. Also sprayed and wiped all surfaces with disinfectant BUT this morning they are back. Not half as many. They are tough little blighters.

 

Yeah I assumed the new ones are eggs hatching, we will leave that room for the time being and see if they die out naturally.

I was considering getting a smoke bomb like were available for greenhouses years ago. I doubt they are as effective now, so might have go with a professional who will have access to chemicals that work.

 

Have blitzed them with bleach as an experiment on the window. I left it for a couple of hours and found the paint all blistered on the cill, rubbed the bleach off and so did the paint down to the wood! The pesky mites are still alive and moving about. It shows how difficult it is to control their cousins, red spider mites, in the greenhouse.

 

We don't have a dehumidifier so are hoping this spell of warm weather and getting plenty of air flow will do the trick, Google suggests these mites can live for 30 days so now we have removed all their food (mould) they will die naturally.

That particular room has always been a problem with damp and mould. I fitted a ventilation unit in place of the air brick which worked well up to now, the fan inside has stopped working in the last month so I think this is our problem.

 

Yes I suppose there could be mould still lurking inside things we can't get at, like computer monitors. We just won't use that bedroom for the time being.
