Spring is the best time to treat to try and grasp better control of the moths. If temps are above 50 degrees now, you can try and use Dormant Oil. This will suffocate them once they come in contact with the solution. Malathion would be a great product to use in the Spring to treat the eggs.
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.
You should use within 24 hours of mixing for best results. Demand SC starts to break down pretty quickly once mixed with water.
It would be best to make the Demand CS application when temperatures are above freezing. This way, the residual does not break down as quickly as when temps are below freezing.
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.
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 is rainfast after it has dried completely. If the product was applied and it rained soon after and the product was not dry yet, it will need to be re-applied.
Yes, Demand CS is labeled for Japanese beetles and can be applied to rose bushes (do not apply directly to blooms).
Demand CS can be applied to the lawn. Dusting is the most effective way to treat yellow jackets and ground nests, using Tempo 1% Dust or Delta Dust and applying directly to the holes with a bellow hand duster. You will want to treat in the evening time when they are least active. Please review our DIY Treatment Guide for Wasps, Yellow Jackets and Hornets for more information.
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.
