Demand CS Insecticide

Demand CS Insecticide - A Great General Insecticide Spray 

One of the best general, all-purpose pesticides is Demand CS. It is labeled for a wide spectrum of pests and can be sprayed inside and outside your home. It can also be used in the yard as well as in agricultural areas. It would probably be easier for the label to list where you cannot use it and on which bugs you cannot spray – it really is that good. Always Read the Label! Start off by reading the label that comes with your Demand CS. It will tell you how much product to mix with water and how to mix for the target pests you are going after. It will tell you how to apply the product, the personal protective equipment (PPE) you need to wear, and it will even tell you how to clean up if there is a spill. Read the label before you start using any pesticides. Having read the label, here is a basic idea of how to treat.

This product targets ants and spiders. Demand CS does not require gloves or a mask as other products do. However, be careful, very careful when using this product. Wash your hands thoroughly after treating as it just makes sense. You will need to mix one gallon of water with one ounce of Demand CS. Since most spiders and ants come from the outside and then go inside, a good barrier around the outside of the house is important. Starting at the base of the house, spray two feet high directly on your house and two feet out from the base of the house onto the ground. Make sure you spray around any entry points like doors and where pipes or electrical wires enter the house. Look for any possible entry points and spray those areas thoroughly. The more thorough you are the better chance you will remain pest free.

Once in awhile you may need to spray inside your home. For these applications use a pin point spray and look for cracks and crevices. Spray under sinks, and appliances. Use it sparingly on the inside, and only when you are seeing pests on the inside. No matter how safe a product is, it is best to use as little as possible around people and pets. Your main barrier should be on the outside. The Label is the Law! To reiterate even further, read the label. Say to yourself, “The label is the law,” over and over again. When you follow the label, you can be much more confident that your house will be pest free and any people and pets will be safe. You will also be able to rest knowing your castle is safe from marauding pests.


Demand CS comes with iCap Technology

Demand CS with iCAP technologyTM solves the most difficult insect pest control problems. Among those are mosquitoes, which are more than just a nuisance to your customers. They also transmit the deadly West Nile Virus. Demand CS helps you control this problem for your customers.

Demand CS is the most active pyrethroid pest control you can use. Its exclusive iCAP technology packs up to 10,000 powerful capsules of insecticide into every square inch of surface you treat.


And Demand CS doesn’t just work better, it works longer. Studies show that Demand CS is up to 200 times more active than other insecticides on flies, spiders, mosquitoes, bedbugs and other insects. That’s because Demand’s iCAP technology shields the active ingredient lambda-cyhalothrin from UV rays, pH extremes and absorption into porous surfaces. So it remains intact longer, ready to be released when an insect makes contact.




Demand CS combines an advanced-generation pyrethroid with a unique capsule suspension formulation for outstanding protection against numerous perimeter insect pests. Essentially, Demand CS consists of thousands of tiny capsules that hold their shape and stay where applied over an extended period of time.

Once applied, the capsules remain on the surface – rather than being absorbed into it – so they are readily available for contact with insects for weeks and months. Because the capsules are lipophilic, they almost magnetically stick to pests as they land on treated surfaces.

Control comes through direct contact of the insect with the cap­sules, with lambda-cyhalothrin transferring from the capsule through the cuticle of the insect, or by ingestion. Demand CS is versatile and convenient. It can be used outdoors for perimeter applications and barrier treatments, as well as indoors for both clean-out and maintenance. This product can be used on porous and non-porous surfaces with little to no odor or staining.

Demand CS effectively controls over 30 different types of insects, including:

  • Ants
  • Bedbugs
  • Bees
  • Boxelder Bugs
  • Carpet Beetles
  • Centipedes
  • Cigarette Beetles
  • Cockroaches
  • Confused
  • Flour Beetles Crickets
  • Firebrats
  • Fleas*
  • Flies
  • Lesser Grain Borers
  • Millipedes
  • Mosquitoes
  • Pillbugs
  • Red Flour Beetles
  • Rice Weevils
  • Saw-toothed Grain Beetles
  • Scorpion
  • Silverfish
  • Ticks
  • Wasps

*Outdoor use only


Mixing Benefits

The iCAP capsule suspension formulation of Demand CS not only makes the product more effective, but also more convenient to apply.

  • Liquid concentrate eliminates dust
  • Stays mixed, resists settling out
  • Does not clog equipment or cause nozzle wear

Tank Mixes

Demand CS is compatible with nearly all labeled insecticides, synergists and additives. When tank mixing Demand CS with another product, always add Demand CS last.

Worker Safety

Because the capsule surrounds the active ingredient, exposure is minimized and the potential for skin sensation during application is greatly reduced.


Demand CS is, available in two easy-to-handle sizes: an 8-ounce container for smaller jobs and a I-quart container for perimeter applications. Both sizes are squeeze-and-pour containers with dual caps for convenient dispensing of either small or large quantities.

Environmental Impact

Demand CS, when applied as directed, has no harmful effect on earthworms, soil microorganisms or soil processes. Demand CS can be directly applied to grass and ornamental plants.

What is the mix ratio of demand CS to 1 gallon of water to control wasp and carpenter bees outside wood porch perimeters?
Michael on Jun 19, 2018
BEST ANSWER: Generally for bee types...
1 US fluid ounce equals 30ml

If treating carpenter bees, spray directly in holes.
I find a 4ml / litre is effective.
After 1 min the bees exit the holes and die.

BEST ANSWER: No sorry we cannot ship this Demand CS product out of the country.
Can the Demand CS be applied with a powered mister/fogger or is it best applied with a hand sprayer?
wandre120 on May 8, 2017
BEST ANSWER: For mosquito control, apply as a structural perimeter spray to
landscape plantings, turf, and building foundations to control
mosquitoes. Yards or other frequented areas enclosed by landscaping
can benefit from the creation of a mosquito barrier
to reduce invading mosquitoes by the treatment of perimeter
vegetation. Apply Demand CS Insecticide at specified rates in 2�5
gallons of water per 1,000 sq ft. Higher volumes applied result in
better coverage and, as a rule, will improve control. Application
to vegetation away from structures may require additional certification,
e.g., in turf or ornamental categories. Consult your state
regulatory agency for requirements.
