    Default spider mites

    I have seen a few tiny tiny bright red/orange spiders on several plants. I assume they are spider mites, but I can't find the point of attack. All leaves are clean of spots and marks and there is no evidence of webs anywhere. They just are walking around, but not doing anything to the plants... yet..

    Do they only attack the leaves or can they attack the roots and thats why i cant find the damage?

    Edited to add:

    Nevermind, I found it is a beneficial predator mite P. Persimilis which eats the spiders mites.

    Can you snap a photo of them, Palito? It would be nice to know what they look like so we can identify them too.

    Spider mites are very tiny, so tiny that you can't really see them. If you hold your plant to the light, and try look at the leaves from the side, you will see something looks like a tiny dust, white green color, and if you use your finger to touch it, it will move. They are usually still, only move when get stired, like from watering. If you can detect them with your nake eyes, they would have done a lot of damage to your plant already.

    My plants have been haunted by spider mites for 2 years, I finally got rid of them with neem oil.

    Default predator mite

    OK they are bright red, fast moving and are sold to control spider mites. They're very effective in killing them all.

    I can see many of those predator mites so they're obviously eating spider mites, somewhere near my orchids, or on them...
