Monterey Sucker Stopper RTU could potentially harm pollinators or other beneficial insects if you were to spray them directly with the product. However, this product is ready-to-use and is applied only to fresh cuts on woody plants to prevent regrowth, so it wsould not be applied in areas like on blooming plants where pollinators would contact it. Please refer to the Safety Data Sheet here for complete safety and toxicology information.
