What are these teeny tiny bugs on my kitchen wall?! 😱

[Bw23]

What are they and where could they have come from?!

Small matchbox for scale.

Have now ascertained they are coming out from behind the tiles.

The kitchen is about six years old and we’ve never had this issue before.

What are they and how do we get rid if they’re coming out from behind the tiles?!

Mites :( we have constant trouble with them, I don't know if it's the age of the house? They can come from Flour etc but definitely from elsewhere too as we find them randomly. Get a strong bug/flea spray and nuke them. Wash what you can. They're a bloody nightmare.

Ugh really?! It’s a Victorian house but the kitchen was newly done by previous owners, all plasterboarded out so I can’t imagine where they have come from or why!

The back of our hob is tiled and they’re coming from under the tiles at the side of the hob. I am bemused how or why they got in there!

Just bumping if anyone know why they might suddenly have appeared and what the source might be.

You need indorex flea spray. It kills everything that walks over it months after you've sprayed it.
