Not 100% sure, Marc.

The Hyponex has thrips covered - provided shelf life ain't blown by winter freezes -

Googled up pics until larvae of Spider Mite matched up about as close as anything. Loupe is only about 15x or 20x. Larvae of these guys weren't amber. More milky white transluscent. And although I didn't stay at a Holiday Inn last night, the adult looked to me like it had an 8 legged gait.
