Insecticides should not be exposed to extreme temperatures such as freezing or over heating or left for prolonged periods of time in direct sunlight. In the case of Demand CS, as long it was only frozen for a very short period of time and after it was thawed out it went back into a solution (the way it usually looks) it should be fine to use. If however it appears that there are particles floating at the top, the product now appears discolored, or the product will not go back into a solution, the product should be discarded and replaced.
