Really tiny bugs are biting me... I HATE THEM!

Location: Argentina, Buenos Aires.

Bug:

In the past few days, in my house we've been having issues with these bugs. Since we live in the outskirts of town a lot of dust comes in, and it all started there, when my sister left her phone on a dusty table and then she found these bugs on her phone, which after like a day or so started biting her, then my father, and finally me. It seems they're dust mites, but I've read you can't see them, so I've also thought of bed bugs, but those are bigger and not only bite, those leave sheets dirty and stuff. Anyways, I'm having sleep deprivation because of these bugs, I can feel them crawl all over my body during the day and especially while trying to sleep. They're leaving me bite marks all over my body, and they are really hard to spot.

These are the bites

What are these bugs? How do I erradicate them?
Since I live in a small town in Argentina, keep in mind that in order to erradicate them I don't have access to a lot of products like in bigger cities or other countries.

Greetings,

Unfortunately, the bug in the video is moving too quickly to be able to make an ID. Try swabbing one gently with a tissue soaked with alcohol to kill it, but not smash it, and post as good an image of the dead bug as you can get. Maybe then someone here can give you an idea of what is biting you...

Cheers!

Could be tick larvae, some species can really move fast like on the video.

I was wondering too about something like mites or chiggers. The bites look a lot like chigger bites, of which I've had plenty, but I've never actually seen the chigger - by the time the itching starts the animal is long gone.
