Bird spikes are a humane way to deter unwanted feathered friends. These durable spikes lay flat until needed, then spring up to provide a natural barrier. Made of lightweight yet strong plastic, they won't rust outside and easily mount to ledges, railings or feeders with adhesive or screws. At just 1.5 inches tall, they're discreet yet highly effective as birds swiftly learn to avoid the area. An eco-friendly alternative to nets or poisons, simply place them where birds congregate to help protect plants, property or statues from unwanted damage.
