Flock-Off irritates birds sense of taste and smell. It does this without causing any harm to the bird. The effectiveness of Flock-Off is proven with birds exposed to Flock-Off rapidly developing a conditioned response to avoid treated crops.
Active Ingredient: Methyl-anthranilate has been found to occur naturally in flowers and grapes.
Length Of Control:
Typically, up to 1-2 weeks, depending on weathering, crop growth etc. New growth is not protected so re-application at 7 to 10 days may be required if bird pressure continues. Monitor regularly and apply a second application if bird pressure and damage is observed. Birds may be observed in the area for 24-48 hours after treatment but will usually leave the area. New flocks entering the treated area within 10 days will move on once 5-10% of the population have been exposed to the taste irritation from Flock-Off and communicated to the rest of the population.
Flock-Off repellence will vary by species.
Flock-Off has proven to be particularly effective on Sparrows, Blackbirds, Starlings,Pigeons and Geese, including Canadian geese.
