Flock-Off contains methyl-anthranilate as its active ingredient. Methyl-anthranilate has been found to occur naturally in flowers and grapes.
Flock-Off works as a repellent by stimulating the ‘trigeminal nerves’ in the bird’s beak, eyes and throat. Although most animals have these nerves, only birds react to Flock-off.
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.
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.
