you can keep spreading mites with water and a pump sprayer yes . had wash them daily slow them down spend hours of time washing scrubbing . and chance mold and bugs keep saying fuck you were hungry. until they are actually take care of properly they come back . that's why out side we see mite infections on trees and the entire bush . and it does rain out side and wind . ill keep using my super strong SAFE poison. , pest strips and mighty wash are only dangerous if you use them crocodile because you don't know how to read directions .so you just tell every body they are toxic . when they first selling mighty wash I was actually at a sales show I am a wholesaler . I did see mighty wash reps open a brand new bottle of mighty wash and drink it straight from the bottle . but to crocodile that is poison as well . I actually do use these pest strips a lot . I do have sheets from iron labs with test results for chemicals mold so on so on . mine come back clean and safe for use .
