Bifen I/T is safe to birds of all kinds if used according to the instructions on the product label. Try to spray during hours when hummingbirds are not active to reduce their exposure to any wet surfaces you may have sprayed it on. Once dry it is completely safe for the hummingbirds to land on surfaces you have treated. If you have flowers in that area, do not spray open blooms but rather around them on the foliage and underneath areas closer to the ground.
