Imidicloprid is fairly stable in the jug. So yes, you can use it next year. Be sure to use it at the maximum rate. Larger trees need more. Uptake is slower. Read the Michigan recommendations from, Dr Dave Smitley.

I found that it was quick and easy. I filled my hand sprayer with a concentrated solution, calibrated to deliver an ounce in about five seconds. Make little holes with a soil probe and add required amount. Put the holes about 6 inches apart, around the circumference of the tree, about 6 inches from the trunk.
