Flash Tape is a visual bird deterrent made from a highly reflective, shiny mylar film and is used to scare birds from outdoor areas. It can keep pest birds away from fruit trees, gardens, vines, pool areas, patios, gazebos, overhangs, boats and more! Each roll of flash tape is 50' long and is meant to be cut into strips and attached to affected areas. Flash Tape is great for repelling pest birds including pigeons, woodpeckers, seagulls, swallows, sparrows, starlings, crows, blackbirds, grackles, ducks, geese, etc.
