We are so sorry for the confusion. This was a printing error and the statement "Please use and activate by 9/1/2022" was printed on the outside box of many of kits. This error has been fixed going forward, but there are some kits in circulation with this erroneous message. This has no impact on the integrity of the swab or the solution inside. Our sterile, gentle, sponge-tipped swab poses no risk to dogs. Swabs, including ones inside misprinted boxes, remain fully effective for at least two years from purchase. For more information about our expiration policy please see: Does the swab expire?
