White tiny bug is killing my pilea peperomia

[PlayerMc]

Hello everyone,

I have a beautiful Pilea that has been dying for a few weeks. At first I thought that the plant could not stand the recent repotting but on closer inspection I noticed very small white insects on the leaves. I thought they were Thrips larvae but I didn't see any adults and for having had Thrips before these insects are smaller and more "round" than the Thrips larvae I had on my Montsera. It could be spider mites but there are no traces of webs on the plant. I took some pictures. Could you help me identify them? Thank you.

Ps : sorry for my english if the sentences look strange, it not my first language.

Hello, this looks like tyrophagus mite to me, but hard to identify from the pictures and you really need a microscope. Predatory mites such as Neoseiulus would feed on this mite.. but it depends on your location and access to biocontrol options.

I see you are in Toulouse, try googling the company BioBest and take a look at their predatory mites. Amblyseius cucumeris would be a perfect solution. Tyrophagus isn't a huge problem on plants, it can feed on other things too, but if it isn't tyrophagus, I mean whatever kind of plant feeding mite you have there, Amblyseius will destroy it
