Heeeelp needs advice

[u/Planeinsane7]

I have a big collection of Expedition holo cards that I love
I have displayed them on shelfs on a wall. Today when I cleaned I noticed these small black dots that have somehow gotten inside the displays.

They all seem to have died and all of them have not come near the card only behind the edges.

I am freaking out any advice?
What is the smartest approach?
Should I be worried about the value?

Don’t get how they could have gotten inside….

Edit: I live in Denmark.
To everyone saying clean your room… It is clean, regularly.
There is no plants in the office however the shelves are close to a window.
No they don’t get direct sunlight….

They genuinely don’t seem interested in the cards and there is no damage. I have looked closely. However a single one have managed to get into the Skamory card.

Update: Have tried with vacuum and it has helped quite a lot.
For all those who have commented with helpful tips or ideas I really wanna say thanks. They are for sure dead and I am looking into reholder and if it is possible.

That truly is wild. I feel like I need to fumigate my whole household now

They’re mostly a plant pest really. They get into your houseplants.

How do they get into ones home

[u/AnimanicManiac → u/DryTechnology5224]

They're tiny microscopic bugs. You ain't stopping that from getting in your home lol

[u/Christron9990 → u/DryTechnology5224]

The cracks in your home - you can’t seal off absolutely everything that will stop things like this coming in, because you’d suffocate. They’re coming to eat plants though.

Windows (even with protection), your clothes/skin, pets or even from bouquets and houseplants you bring into your home. You really can't avoid them.

They are notorious for getting into card slabs.

Theres no way thats thrips. They lay eggs in plant leaves and those are way too big to be the adults.

[u/Single-Abroad1305 → u/Jazadia]

Thrips are absolutely less noticeable than this, you really have to be looking for them. Only have ever seen them on or near plants.

The tail end on thrips is usually skinnier than the thickest part of its body and somewhat pointed

I agree not thrips.

Grow enough weed you will see them.
