I live on a boat in the UK and keep finding more and more of these little tiny white insects (mites?) under the things in my cupboards.
They vary in size only a very small amount and are all approx 0.5 to 1mm long.
They appear white unless seen when illuminated on a light coloured surface.
Any ideas what they are? If they pose a threat to our health/woodwork? How to get rid of them?
I think these might be psocid nymphs
There are some good images of nymph and adult here
(ignore the fact that the site concerns Indonesia)
Do a bit of research in that direction and see if it seems to fit.
Yep, I think you've hit the nail on the head. I think they're also sometimes referred to as Book Lice.
I found a load of them under a food storage container in a locker. We emptied all lockers and deep cleaned them, and everything in them, and sprayed insecticide everywhere then went ashore for the day to let things settle and dry.
On our return we saw a number of them little beasties on their backs with their legs in the air.
After reading your links I suspect we'll still have a considerable number of their eggs lodged here and there so will probably buy some 'Crack and Crevice' bug killer and apply liberally.
Since doing the above, we have not seen a single one of them.
Interestingly, they were very intelligent seeming insects. Whenever one was encountered it seemed very much like it was previously just going for a stroll - but then became aware it had been spotted and immediately high tailed it to the nearest cover - in a non-linear path, attempting to avoid capture. Surprisingly quick for their size.
Thanks for your help!!
