Roundup products are non selective herbicides that kill everything they are applied to so we cannot see any valid reason to mix it with Sevin Concentrate unless you want to kill the plant/grass area you are trying to control the listed insects on. That being said, as long as both product labels are followed you could do so but we would recommend doing a compatibility test.
