Demand CS Insecticide - Questions & Answers

Demand CS is a water-based insecticide and should not cause damage to any surface that water would not damage.

It is not usually required to use a surfactant with Demand CS.

Bed Bugs have shown resistance to Suspend SC. Demand CS is microencapsulated and will have a longer residual. It takes more than one product to treat for Bed bugs and this is why we recommend using one of our Bed Bug Kits.

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.

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.

It is highly recommended to apply mixed solution of Demand CS within 24 hours of mixing. This will make sure you are applying the freshest and most effective mixture.

Yes, you can use Demand SC even though you have already sprayed, although you would want to wait 7 days between treatments. Stink Bugs will try to emerge in the spring and common places that people find stinks bugs are in the window sills and this is a great place to treat along with the baseboards, back behind and underneath appliances, in attics, and where pipes enter the the wall. Demand SC is safe on aluminum and composite frames and will not harm any surface that is tolerable to 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.

At the highest usage rate you will use .8 fl oz of Demand CS per gallon of water to cover a 1,000 sq ft area so each quart of Demand CS will make 40 finished gallons of solution which will treat 40,000 sq ft.

Talstar (and we hope they are adding an insect growth regulator such as Archer IGR to the product mix you mentioned) should do a great job for you. If you wanted to use something with a little more strength you could try Demand CS or its generic Equil Lambda CS. These products contain lambda-cyhalothrin and they are micro-encapsulated which makes them last a little longer on outdoor surfaces. You should remember that ticks may be hidden in tall or dense brush so higher treatment volumes may be needed to treat the entire plant, not just the top side of the plant where it is easiest to spray. You should try to get the application on the underside of leaves and all the way to the bottom of the plant. When you are dealing with an area that has a high tick population you may be required to treat once a month from spring through to the first frost, no matter what product you use. The problem on your property may be that ticks are being reintroduced into the area on a consistent basis by wildlife such as deer, raccoons or birds. You will be required to use non-chemical means to reduce the tick population in addition to insecticides. As with most pests you can modify the environment on your property to make it less favorable to ticks. Keeping grass and weeds cut short in tick infested areas increases tick death during hot weather, discourages wildlife and will reduce the amount of vegetation which may need a pesticide application to kill ticks. Clear away yard debris such as old firewood or leaf piles. Remove old or abandoned bird nests and rodent nests. Patch fences where wildlife may be gaining access to your property. It may also be helpful to have the ticks identified. By identifying the type of ticks you can better understand what type of animals may be bringing them to your property and you can modify the environment to make it less favorable for that host animal. You can contact your local cooperative extension office to request an insect identification.

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.

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.

Demand CS should be mixed at 6-12 ml per one gallon of water per 1,000 sq ft per the product label, which is 3-6 mL or 0.1 – 0.4 oz per half gallon of water.

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. Asian beetles enter the structure through cracks and crevices, especially around windows and doors. Be sure to treat these areas thoroughly once a month through November. Please click on the product label for detailed instructions on application.

Per the manufacturer it is recommended to use anywhere from 0.2 to 0.8 oz/6 to 24 ml per gallon of water.  If you need to make 50 gallons of mixed solution you would use 10-40 ounces of Demand CS for 50 gallons.  Always follow the product label provided by the manufactuer.

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. 

Demand CS and Equil Lambda 9.7 CS are pretty much identical in every way. Both products are micro encapsulated and both will last for about the same amount of time and both treat the same insect pests. Really the only difference is that they are made by different manufacturers.
