whats up i had the same exact problem, about 3 weeks ago dont know where they came from but they were there pretty bad so i did a lot of research about the bug methods of death for the bug old wives bs untill i found this product from the company hot shots. there called no pest strips. i was iffy about chemicals but the plants were suffering bad and it was either end their misery or try it. i did and the shit worked 2 weeks later no mite on any plant at all they dissapeared and my plants bounced back with no ill effects i paid 6 bucks a peice at home depot, they look like air freshners, the only other imediate remedy is preditor mites. they work good but i didnt want to wait for the mail or not buy enough. anyways thats what i did good luck.
