I have a 57x53 ft. back yard ,front is about the same and have a terrible problem with grubs. I have used the bayer 24 hour kill in may and imacloprid in fall and still have a problem .I need to kill the ones that are hibernating from last fall and then the ones after egglay in august. I will be buying a bag of Merit but how long is the shelf life. and can I store it in the garage,I know to keep it clean and dry but will the cold affect it?
Normally grubs are most active between may and june and this is the most common time that products like the Merit are applied. You want to store it in a cool dry, temperature stable place and will normally keep for at least 3 years.
