Flashes and reflects light to repel birds, deer and nuisance animals. Each pack of Repeller Ribbon contains 30 meters (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 meter lengths and hang. For protecting vegetable crops, seedling and newly seeded lawns stretch lines of tape between posts at a height of 0.5 – 1 meter above ground level. Alternatively, use a “maypole” arrangement by stretching lines from a tall center stake and pegging them into the ground.
