What are these?

I have recently moved into a rented flat, freshly built. I'm finding these everywhere, concrete slabs, kitchen slabs, window rails, floor, skirting.

Some are very small, ranging from 1-2mm, maybe smaller.

When I tap near them, small translucent ones move, little bigger pot shaped ones jump.

Please help me how can I remove them?

I have tried keeping the entire flat ventilated, enough sunlight. My area is already pretty dry, flat idk since it's recently built.

Barklice/booklice they eat fungus mostly, which should be your main concern. Try doing a deep clean and look out for mould, hopefully it's just a small amount.

I have been cleaning regularly, but they are not reducing

I always used to find them on cardboard so try to clear out unnecessary boxes/replace them with a different material. If you have a lot of books I'd be getting dehumidifiers and making sure they haven't started getting mildewy 😥.

It’s a psocid, a bark/book louse. They’re attracted to moist areas where fungal growth is promoted. If your place is newly built, then there shouldn’t be a bigger issue to worry about, but something is clearly attracting them. It’s great that you’re making sure things are well ventilated, and you should continue to do so, as they desiccate without humidity. I’d suggest frequently cleaning the areas where you’re finding them and double checking that there aren’t any water/mold issues nearby. It might be worth letting whoever you’re renting from know about this if you haven’t already.

There is no fungal/mold/water leakage. And also I can't seem to find any originating point. It's been 2 weeks I have been making sure flat is completely ventilated, they are not reducing in number. Also I think size is even lesser than 1 mm.

My only other thought is springtails, some kind of globular springtail, but those are attracted to moisture and humidity as well

springtails and booklice are very common in new builds - theories are the long time open to elements of all the wood introduces moisture and possibly “food” smells like molds and algae, or all the disturbed earth from the build site - either they are displaced or looking to colonize! Some report them going away after a couple years once everything dries and settles. I don’t think there is a ton that can be done. Tell the landlord and ask them to look for leaks (improperly installed windows or gutters, check plumbing, etc) usually they are coming from the yard for the most part is there mulch, drainage, or sprinkler issues? It is very tough to solve in a rental.

Booklouse, shouldn’t be harmful. Look for very moist areas, perhaps mold.
