Debra writes,

Is there an expiration date for Hi-Yield weed killer?


Insecticides and Herbicides do not have an expiration date.  Most all insecticides and herbicides are made to last for years and years on the shelf.  Most all will last at least 5 years as long as you keep the lid on tight and keep it out of direct sunlight and areas of high heat.  You should shake the bottle to prevent settling of active ingredients every few months to extend the life of the product in the bottle.
