I don't have a clue why everyone sais the bugbombs,the hotshot pesticide strips,or even neem oil takes care of spider mites i've used all of these products thoroughly and nothing came of mites except repression then they vigorously came back. I find it funny when people say these products work. These company's are making tons of money on you guys and you get no results in return. Their are products to take care of them,I know i have a product that never fails always 100% yet I can't disclose it on here. I'm not sure about the mighty wash product but my advise would be not to use any of the ones I mentioned for you will be wasting your money. Goodluck,Oregon the Chronic StAte.
