Humidity without insects !

[BeexDD]

Hey !
First of all,I'm brand new here ! Hope I will be of good help and learn a lot of things about orchids,facts that are not that accessible and help you keep your orchids healthy and beautiful all the time.

There's one problem that I've been always coming up against...the proper and fruitful umidity!
Whenever I try to raise it in order to help my orchids develop in a moist environment,I happen to notice those little white jumping insects in the bark when I water the plants,I don't know what their name is or how to get rif of them FOREVER !
I tried to kill them with weak repellents,and it worked at the moment,but in the future they would appear again !


Does anyone know what do I do wrong ?
What am I supposed to do so as to never see them again,and,in the same time,to be able to provide my orchids the high humidity they need ?
Plese,I am going crazy !
