    Mites are tricky but the Forbid kicks their butt! Also, it is an effective ovacide so one application eliminated my infestation.

    5 of 5 Stars  absolutely the best miticide avaliable
    By Wit in eastern, maine on December 23, 2014

    I have tried NPK Mighty wash, Einstein oil, Avid and about every product out their with little to no results. I finally bought Forbid 4F and with one heavy application the might were gone after 3 days and did not reappear. Most products want you to soak or spray under leaves and forbid you only need to spray the tops which in my case growing scrog is very hard to get at the undersides of leaves. I spray once at the start of veg cycle and once at the start of bloom and nnever have mite issues. I even brought 2 might infested plants into room the day I treated my crop and the mites I brought in also died off. I would recommend this to everyone but please make sure you wear gloves and a respirator when applying and don't use to close to harvest......A+ product and mites won't built resistance to it

    By Croppin in Humboldt ca on September 2, 2015

    Don't fumble around with other miticides if you're money's on the line, just pay the 200 bucks, soak 'em and sleep tight knowing all mites+ their eggs will be dead in no time.

August 26, 2013Scott from Jacksonville Fl asked:

QHow much Forbid 4F do I add to a gallon of water for application?
My book on my bottle of Forbid got wet & unreadable. I just want to make sure I don't burn my garden, thanks.

AThe label states to use 2-6 Ml into 5 gallons of water. So you would approx. 1.2 ML into one gallon water.

QApplication rate of Forbid 4F
Can you tell me what the application rate would be? I have a 30 gallon spray tank and for spot use, a 2 gal. sprayer. The 30 gallon sprayer with 25 ft. hose I use for yard duty on over 100 trees and shrubs.

AYou did not specify what type of pest you are using the Forbid 4F for so we are unable to accurately answer your question.  Please refer to the product label for complete instructions depending on your pest.

July 17, 2015Daniel from Higginsville asked:

QAt what temperature will Forbid burn the plant (Alberta Spruces and Arborvitae Trees)?
And should I still use Hawkeye Adjutants?

May 12, 2015Donna from Canterbury, Ct asked:

QCan you tell me how long Forbid 4F will remain viable once it is mixed with water?
Sometimes after applying the product I have a little left over. I've heard it has a short "shelf life" once it has been mixed for application?

AOnce Forbid 4F Ornamental Insecticide Miticide has been mixed with water, we recommend using all of the mixed solution within 24 hours.  Any solution that has not been used after 24 hours should be discarded.
