Flashes and reflects light to repel birds, deer and nuisance animals. Each pack of Repeller Ribbon contains 30 metres (100 feet) of tape. For best results always apply Repeller Ribbon before bird damage begins. For protecting fruit trees and vines, or deterring birds from roosting and nesting in eaves, cut the tape to 1 metre lengths and hang. For protecting vegetable crops, seedlings and newly seeded lawns, stretch lines of tape between posts at a height of 0.5-1m above ground level. Alternatively, use a 'maypole' arrangement by stretching lines from a tall centre stake and pegging them into the ground.
