Scarecrows can be made out of almost any material including straw and wide plastic streamers. Use bright colours such as red, orange and yellow. Mark large eyes on the scarecrow. Allow arms and legs to flap in the wind. These include sirens, pots and pans and pyrotechnics such as automatic exploders, whistle bombs, screamer rockets and shell crackers.
Many people use automatic exploders, which make a loud noise without discharging a projectile.
Set exploders to fire every five to 20 minutes. Turn exploders off after dusk and on at dawn so that they don't disturb neighbours. This will also save on fuel and help ensure that the geese don't get used to the sound. All pyrotechnics should be fired to explode in the air just over the geese. This is most effective and reduces the risk of fire.
