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 should be applied when there is no rain the forecast for 24 hours after application. The outdoor residual of the product is up to 30 days. Heavy or prolonged rains can diminish that residual slightly.
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.
You should use within 24 hours of mixing for best results. Demand SC starts to break down pretty quickly once mixed with water.
It is not usually required to use a surfactant with Demand CS.
The manufacturer recommends that you use a buffering agent when the pH is not between 5-7 per the product label instructions when applying Demand CS.
Demand CS is labeled for a variety of insects, including Asian Beetles. The key is to treat early enough (early fall) and to apply the product in the right places.

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.
