Avid, is for ornamentals, & is very nasty stuff. Pretty much Agent Orange-grade biowarfare. Pretty sure Forbid is the same. If you use it, know this: It works, but if it's not done to exacting spec it'll cost you your plants.Avid and forbid 4f in veg only, not in flower. They are very effective and you can find them on ebay at reasonable price.
Mightywash kills on contact and can be used in flower and kills the mites and eggs.
Avid is NOT food safe, nor are the residuals remotely safe to smoke. Avis is used for ornamentals, it's not approved for food crops. You have to wear gloves & respirator when applying it. Most pot growers avoid it, and in WA, CO, CA etc marijuana that tests positive for it cannot be sold, by law.If it's not done to exact spec, it'll cost you your plants, that will happen with almost anything you use if you don't follows the specs.
The chemical in avid and forbid are used on different crops that we eat daily. I've never had problems with them affecting my plants,
but you should do your own research on any product before you use it.
