Bought in 2018, would it still be effective?
Per the manufacturer, ZoGuard Plus For Dogs does not have an expiration date. This product should always be stored in its original container and at room temperature to ensure that it maintains its effectiveness.
From the manufacturer: "Unlike FDA products, EPA-registered products such as ZoGuard Plus do not carry a "stamped-on" shelf life or expiration dates. However, the EPA does require a mandatory 2-year storage stability. Our products have satisfied the EPA requirement and well beyond."
