I finally figured out the pests I had to deal with.

After all this time, I have a friend who deals with controlling pest for greenhouses, and she identified the mites I had to deal with. I knew that all the humidity in the room made no difference..What has this year is treating them with Neem oil a few weeks ago, and COOL moist conditions with constant moving air. I have been bug free for weeks now, since my last post. a huge accomplishment! Hope this info helps someone..

DESCRIPTION OF THE PEST

Broad mites are often found in depressions on fruit where the females lay their eggs, which are dimpled, translucent, and covered in white speckles. These mites are so small you need a hand lens to see them. Broad mites are yellowish in color and adult females have a white stripe on the back.

DAMAGE

Broad mites feed on fruit and leaves, preferring young fruit up to about 1 inch (2.5 cm) in diameter that are located on the inside of the canopy or on the inward facing side of outer fruit. Feeding results in scarred tissue that cracks as fruit grows, leaving a characteristic pattern of scars and new tissue. Although most feeding occurs on fruit, broad mites may also feed on young expanding leaves causing them to curl. This cupping and curling of leaves can appear similar to mild damage caused by glyphosate-Roundup applications.

MANAGEMENT

Broad mites are occasional pests of coastal lemons from late July through early October; infestations are enhanced by the presence of Argentine ants. This mite often occurs in conjunction with CITRUS RUST MITE, with the rust mite usually predominating in number. Populations of broad mite tend to be most severe in "WARM HUMID" conditions such as found in greenhouses. No treatment thresholds have been developed for broad mite in citrus. If high and increasing populations warrant treatment, use miticides with the least toxicity to predaceous mites.
