We are committed to reducing waste in our world so we have come up with a plan to help further the effort and YOU can be a part of this too! We have Fly Bye Plus fly spray refill stations located at the retailers where our products are sold. Just bring in your empty Guaranteed Horse Products gallon or 2.5 gallon container and refill it for a fraction of the cost! You save money and reduce waste in one action. If you would like to see a retailer near you support this program, please send us a detailed email and we will take care of the rest. Thank you so much for your continued support and green efforts!
