Generally speaking, all insecticides need to be kept at room temperature area to prolong shelf life. You don't want to expose any insecticide to direct sunlight, high heat or freezing temperatures, as this could break the product down, and it will lose effectiveness. If your bottle of Demand CS was left outside for a week, there is a good chance it could be ok, depending on what the temperatures were that week. If the product isn't seperated at all or clumpy and mixes well with water, then it should still be fine to use, but it may not have the residual that it had before these conditions.
