AaaaaaaaGGGGGGGGGGGGHhhhhhhhhhhhh!!!!!!!!! IT look's like the dreaded Spider Mites to me also....Good Luck I seem to have to fight them in the spring when my rooms warm up above 75 degree's the egg's start hatching usually there will be tiny eggs where the yellow spots are ...get your self a magnifying glass or a jewler's loop and look very closely and watch for movgement they can be very hard to spot.
