Spider mites?

Red spider mite I believe. The link below describes spider mites in general. Note that it mentions spraying insecticides to get control may aggravate the problem because you can kill off the beneficial insects that prey on them (and bad guys always come back first!). They thrive in hot dry environments, so cultural controls would include creating a humid environment and periodically spraying off foliage.

Down south we call these Chiggers.

We call them chiggers, too...have never seen them on plants.

The larvae of these critters are chiggers, don't think they harm plants....

Here is some info....

Chiggers have 6 legs and this appears to have 8. At least as far as I can tell from the image. Not spider mites, which wouldn't be found running all over the place, except for the plants! I'm going with a type of clover mite, or a velvet mite.

It looks like a velvet mite to me. They are all over the place here in Maryland. They will not bother your plants. they actually eat other mites and their eggs, and snail eggs. So seeing them means that they are feasting on some other nasty bugs around your deck or garden.

We have the same thing. I live in Indiana. Unfortunately they are a nuisance...will crawl on you. Any suggestions on how to control them...any sort of spray?

Erythraeid mites. Info in first paragraph of below link.

I have these tiny red, fast bugs running on my cedar deck; if they are chiggers, I am concerned then to enjoy relaxing on my deck; if they are not chiggers, would they damage the wood structure eventually?
Anybody has any suggestions?
