Yes, you can mix Demand CS and an IGR such as Gentrol in the same tank at the same time. You would clean your equipment with water and a tank cleaner, if needed.

When using Demand CS it can take minutes to hours to kill stink bugs. The active ingredient needs time to work through the follicle of the insect to the central nervous system.
Demand CS is not labeled to be used across open carpeted areas. For inside the home, Demand CS is labeled to spray along baseboards, crack and crevices, and under appliances which is great for most insects but not for carpet beetles. Please take a few minutes to read our How to Control Carpet Beetles article for an in depth explanation of how to control this pest. It is very important that the source of the infestation (where the damaging larva is harboring) is discovered and eliminated, not just the visible adult insects you see wandering around. Until you find out what that is and deal with it you will continue to get more of the carpet beetles emerging from hiding.
Demand CS is a great general pest control and works well for spiders, earwigs, ants, mosquitoes and many others. It should be applied monthly outside and inside quarterly. It would be safe if to apply when the dogs are not present until the surfaces are completely dry.
As long as you keep pets/children out of the area while you treat and until the Demand CS application has had time to completely dry or settle it is safe for pets and people to return and resume normal activity typically after 4-6 hours when applied outside, about 1 hour inside
Demand CS dries clear and leaves no visible residual when used as directed on the product label.
There is only Demand CS, we are not aware of a Demand SC product. One of our roach control kits would be more recommended for roach control. These professional kits includes non-staining, low odor concentrated insecticide for spraying the outside perimeter of the home and inside underneath appliances, behind cabinets, under toilets and sinks, etc. You'll also get Roach Bait Gel to help get rid of those roaches that like to hide. Baits can be applied up high in the kitchen in the corner of cabinets and in cracks and crevices in kitchens and bathrooms. The bait contains a slow-acting poison that attracts and kills feeding roaches, who also spread the bait to other roaches by contact or by sharing food. Finally, an Insect Growth Regulator is offered which will stop roaches from laying eggs, helping to halt the infestation. The combination of an IGR with roach bait is a highly effective roach control strategy that is widely used by pest control professionals. The insecticide must be applied with a 1 gallon pump sprayer.
