What is the shelf life of Bayer Advanced 12 Month Tree & Shrub Insect Control?

How long will the product stay effective after opening? A one-gallon container is a lot of material for me. I suspect that I would only use about half of it the first time and the second half twelve months later. Will the product still be effective?

Answer:

You can expect the product to stay effective for at least 3 years from the date of purchase if it is stored properly. Keep out of direct sunlight and out of extreme temperatures.
