Problem guests

They almost look like barklice as they are called, also related to booklice. They like Humid places with mold. Yours looks different though.

 

They do look like book lice or bark lice. They're not harmful to your plants, but imagine they could get annoying in large numbers. Most advice suggests lowering your humidity. I don't think that will happen. However, one site recommended Cy-Kick for control. Since the active ingredient is cyfluthrin, Tempo should also work, or stuff like Talstar as well since it's another pyrethroid.

 

To me they look like termites. we have many of them around here. They don't eat plants, but once I found them in my dendrobium pot, ruined the medium, and brought soil into the pot. Termites are capable to cause serious damage to a big building.
