Is it okay to make up a gallon to have on hand when needed, or does it not last long in solution?
You should use diluted solution of Demand CS or other insecticide concentrates as soon as possible and within 24 hours. After this time, the active ingredient breaks down quickly in solution. Shelf life of the concentrate is 3-5 years when stored in a temperate environment out of direct sunlight.
