Demand CS

Demand CS is a water-based insecticide concentrate that offers excellent indoor and outdoor pest control. Demand's micro-encapsulated technology means that when you apply it, it leaves thousands of micro particles that bind to the surface offering long-term protection and fast insect knock-down. In fact, Demand CS is up to 200 times more active on flies, mosquitoes, and other insects than other insecticides. Demand CS controls more than 30 common insects including spiders, ants, flies, wasps, fleas, ticks and bed bugs. It can be used both indoors and outdoors with little to no odor or staining.

How Demand CS Works

To understand how Demand CS works you must first know what it is. Demand CS is a microencapsulated water-based formulation offering superior insect control. Compared to older pyrethroid materials that have been used for many years with declining results, it is up to 200 times more active on flies and other animal health pests allowing lower rates. And it’s designed not only to work better, but to work longer. Demand CS controls over 30 insect pests including: Ants, Bees, Carpet Beetles, Centipedes, Cigarette Beetles, Cockroaches, Confused Flour Beetles, Firebrats, Fleas, Ticks, and more.

Demand CS combines an advanced generation pyrethroid with a unique capsule suspension formulation for outstanding protection against numerous perimeter insect pests.

Once the formulation has been applied and dried, lambda-cyhalothrin, the active ingredient, is released from the capsules. Control will occur primarily through direct contact of the insect pest with the capsules, with lambda-cyhalothrin transferring directly from the capsule to the cuticle of the insect. It is also possible for the capsules to be ingested in the case of insect pests which preen themselves such as cockroaches.

Target Insects

Large variety of yard, home and ornamental pests, including but not limited to:

INSECTS CONTROLLED: • Ants • Aphids • Armyworm • Azalea caterpillar • Bagworm • Bed bugs • Bees • Beetle • Black turfgrass ataenius • Black vine weevil • Bluegrass billbug • Boxelder bugs • Broadmite • Brown soft scale • Budworm • California oakworm • California red scale (crawler) • Cankerworm • Carpenter bees • Carpet beetles • Centipede • Chiggers • Chinch bug • Cigarette beetles • Clover mite • Cluster flies • Cockroaches • Confused flour beetles • Crickets • Cutworm • Earwigs • Eastern tent caterpillar • Elm leaf beetles • European sawfly • Fall webworm • Firebrats • Flea beetle • Fleas • Flies • Forest tent caterpillar • Grasshopper • Grubs • Gypsy moth larvae • Hyperodes weevil • Japanese beetle • June beetle • Lace bugs • Leaf skeletonizer • Leaf-feeding caterpillar • Leafhopper • Leafminer • Leafrollers • Lesser grain borer • Litter beetles • Mealybug • Midges • Millipede • Mites • Mole cricket • Mosquito • Oleander moth larvae • Parasitic Wasp • Pillbug • Pine sawfly • Pine shoot beetle • Pineneedlescale (crawler) • Pinetip moth • Plant bug • Red flour beetles • Rice weevil • Root weevil • Sawfly • Saw-toothed grain beetles • Scale insect (crawler) • Scorpions • Silverfish • Sowbugs • Spider • Spider mite • Spider Mite, (two-spotted spruce) • Spittlebug • Striped flea beetle • Striped oakworm • Termites • Termites, (above ground only) • Thrips • Tick • Tip moth • Tussock moth larvae • Wasps • Webworm, sod • Whiteflies

Target Uses

Demand CS Insecticide Concentrate is ideal for general, broad-spectrum pest control, perimeter applications, and crack and crevice treatment indoors.

See complete list of pests below.

ACTIVE INGREDIENT: Lambda-cyhalothrin 9.7%

Application Instructions

*** Always read product label and directions completely before using ***

Use indoors (crack and crevice only) and/or outdoors. Best applied with a 1 gallon sprayer. Apply to outside foundation and all entry points such as around windows, doors, etc. Always read the label completely before use.

  • 8 oz. bottle yields 10-40 gallons of finished solution for standard application rates.
  • Quart (32 oz.) bottle yields 40-160 gallons of finished solution.

Standard Application Dilution rates / Mixing Ratios:

  • 0.2 fl. oz. (6mL)/gal. of water – 0.015% -  light infestation, maintenance, general crawling pests
  • 0.4 fl. oz. (12 mL)/gal. of water – 0.03% - moderate infestation
  • 0.8 fl. oz. (24 mL)/gal. of water – 0.06% – clean-out, severe infestations, scorpions, spiders

Watch the video on this page for general use mixing and application instruction using a 1 gallon sprayer.

Use in the Following Areas:

In, on and around buildings and structures for the control of listed pests, including on lawns, ornamental trees and shrubs around residential, institutional, public, commercial, agricultural and industrial buildings; and parks, recreational areas and athletic fields; food handling establishments; livestock/poultry house structures; pet kennels.


  • Use as a crack and crevice treatment only. May apply at 21-day intervals. Remove pets or children from treatment area until product is dry.
  • For bed bugs – Use 0.2-0.4 fl. oz./gal. of water. Do not apply to bedding or to mattresses or furniture surfaces where people will be laying or sitting.
  • May be converted to a foam for treatment in structural voids.


  • 1 Gallon of finished solution will generally cover 1,000 square feet when using a hand pump sprayer for spot or perimeter treatments.
  • If using a hose-end sprayer, calibrate to 0.2, 0.4, or 0.8 ounces, and use 1-5 gallons of water per 800-1600 square feet. Higher volume applications will result in better coverage, particularly for mosquito control.
  • For ornamental pests – Use 1.5 – 5 fl. oz (44-148 mL) / 100 gallons of water – May be applied at 7-day intervals if necessary. Use lower dilution rates for more frequent applications or limit to spot treatment. The addition of a spreader sticker may increase application to waxy foliage.
  • When using large tank mixtures, use a buffering agent if necessary to keep pH from 5-7.
  • For lawn and turfgrass pests – Use 3.4-7 mL/1000 square feet or 5-10 fl. oz. / Acre
  • For thatch or subsurface inhabiting pests, use irrigation after application or higher water volumes to carry the active ingredient to the target pests.


  • Pet safe when dry
  • Virtually no odor or staining
  • Low mixing rate is economical
  • Labeled for applications in food-handling establishments
  • iCap technology creates a longer-lasting, more effective insecticide concentrate

    5 of 5 stars  Excellent product
    By Eric in Scottsdale, AZ on 06/09/2009
    Verified Purchase

    We live at the base of the McDowell Mountains in North Scottsdale where crickets, spiders and scorpions are everywhere. I applied Demand CS right before sunset and the following morning it looked like an atomic bomb went off in my yard. Dead crickets, black widow spiders, cockroaches and last but not least the follow evening a slowly dying scorpion in our bedroom that accidentally crossed the wrong path. In nearly three weeks since we applied the product, I have yet to see ONE single cricket, spider, or cockroach. Great product!

    5 of 5 stars  Great stuff!!
    By Lauren in Gates, NC on 04/29/2010
    Verified Purchase

    We own a log home and have been plagued by carpenter bees. We have tried several other products: powders, liquids, professional and home store strengths and this is by far the best! It is non staining and easy to apply with a garden pump sprayer. After application, we watched the bees hover a minute and then decide to take up residence somewhere else.  Those that stuck it out, were dead in the morning. It is almost instantaneous! We also applied it to our barn and found it killed bugs that we didn't even know we had a problem with. Try this product= it works!!!

    5 of 5 stars  Ants, crickets, and roaches no more...
    By Gregory in Tempe, AZ on 04/15/2009
    Verified Purchase

    We have tried several pest control companies to eradicate our recurring summer sewer roach problem to no avail. When the city treats the sewer drains and manholes, the roaches come into our yard and house. We also live in an area with crickets and tiny black ants. Nothing seemed to stop everything until we tried Demand CS. I read the label carefully and found that the strongest wipe out dose was for scorpions. I carefully measured, mixed, and sprayed the yard, block wall, foundation, windows and doors. The next morning was like a nuclear winter. Dead roaches, ants, and crickets everywhere. Our gardener cleaned them up like leaves. We now use the maintenance dose every three months and have not had a pest in a year. Awesome Stuff!!!

    5 of 5 stars  This is magic!
    By Steve on 09/04/2008

    Bought a neglected house with roaches all over the yard. After spraying 24 gallons of Dursban over a two month period I was still seeing too many roaches to count at night. I put Demand CS down and the next morning had over 60 dead roaches, 30+ more the following day and in 1 month and only 2 applications I'm down to 1 or 2 a day outside (dead) and none inside in a month. I've been outside at 11pm on hot nights and not seen one live roach! This is magic.

  • 5 of 5 stars  Carpenter bees gone
    By Matt in Fair lawn New Jersey on 05/20/2018

    I have had carpenter bees for about 3 years in my 2nd story fascia board. Every year I went to Home Depot and got their sprays for carpenter bee control which never worked. I order Demand CS and followed the ratio for the mix and directions for spraying. True to what the bottle said they were gone from all three entry holes within 3 days, I am impressed!!. It has been 3 weeks since I sprayed and no bees go to the fascia area. Thanks for a solution to my bee problem

  • 5 of 5 stars  Demand CS
    By Walter in North Port, Fl. on 05/05/2018

    This stuff works! I use outside the house at the foundation 2ft up and 2ft out. Ants are stopped and stay away for about six months. Last night walking the dog, I noticed a cluster of ants at my driveway. They were coming from across the road. After putting the dog in the house, I mixed a gallon of Demand CS at 24ml to 1 gal. Sprayed the ants and their trails. After 5 mins they were staggering around. The next morning, all were gone. I told my neighbor about this product and he cancelled the treatment company to do it himself.

QWhat's the difference between Demand CS and Suspend SC?

ABoth products have an active ingredient that is classified as a synthetic pyrethroid, so they really are very similar in the way that they work.  Suspend SC contains the active ingredient deltamethrin and is a bit more versatile when it comes to bedbug treatments though as it can be sprayed on mattresses, carpets (spot treat only) and on furniture (crack and crevice only). Demand CS cannot. Demand CS contains the active ingredient lambda-cyhalothrin, and it is micro encapsulated which will make it last a little bit longer in outdoor applications.

QIs Demand CS safe to use around children and pets?
What's the risk of transfer since Demand CS is capsulated? For instance, we have hardwood floors and we vacuum the floors and the baseboards. Can the insecticide be transferred from the vacuum to another surface (such as when vacuum rugs and couches) and increase the risk of contact?

AIf you are applying the product correctly, it should only be in cracks and crevices and other closed off areas. There should not be any issues with transfer effect like you are speaking of.  Once you apply Demand CS, the tiny microscopic balls of insecticide will bond to porous surfaces and will not be removed by general cleaning or vacuuming.  You should allow 30 minutes after application for the product to dry before cleaning or allowing children and pets to re-enter the room.

QDoes Demand CS kill stinkbugs?

AAbsolutely.  Although stink bugs are not specifically on the label, the active ingredient Lambda Cyhalothrin in the Demand CS has shown great results on Stink Bugs. Many of our customers buy Demand CS for stinkbugs and the customer feedback has been great in regards to the results.

QShould I mix Demand CS with Suspend SC and Gentrol?
I've seen the ability to mix Gentrol with either Demand or Suspend, but can all 3 be mixed? Seems this would offer the best combo for heavy knock down, lingering kill, and nymph control to potentially pyrethin resistant bed bugs. Also, can you confirm the pyrethrin resistance rumored in bed bug populations?

AThere are indeed strains of bedbugs that are resistant to synthetic pyrethroid insecticides. Synthetic pyrethroids such as Suspend SC and Demand CS are the man-made versions of natural pyrethrin insecticides such as Exciter or Pyganic Pro. There is no valid reason to mix Suspend SC and Demand CS together, it would not make either product work better or produce better results, though it could make treated areas repellent to bedbugs lessening the effectiveness of the treatment. Both Demand CS and Suspend SC can be mixed with Gentrol IGR for a good knockdown and to break the growth cycle of the bedbugs and their eggs. If you do have a problem with a pyrethroid resistant bedbug population, you should use Phantom and Gentrol together. Phantom is not a pyrethroid, it is from a class of insecticides called pyrrole and there is no known resistance from bedbugs to this product. We also highly recommend that you use an aerosol with a straw attachment such as Phantom aerosol for the small cracks and crevices and a dust such as MotherEarth D for long lasting residual control.

QIs spraying Demand CS to eliminate bed bugs in the house perfectly safe for my children under 8, and my dogs?

AUsing Demand CS indoors for bedbugs is safe as long as you follow the Demand CS product label. Be sure to have all children and pets out of the area while you are doing the application and they can return as soon as the treated area is dry.

QWhich is better for perimeter outside Demand CS or Termidor Sc?


Demand CS would be a great choice for general pest control for common insects found in and around the home.  It can be applied every 90 days indoors and every 30 days outdoors. Termidor SC should ONLY be applied once every 6 months directly up against the structure on the exterior of foundation (1 ft up and 1 ft out). You should NOT apply Demand CS in the areas where you apply Termidor SC.  Please refer to the product label prior to mixing and applying for complete usage instructions.

QRotating Demand CS and Termidor SC
I plan to mostly use Demand CS for insect control on the outside of the house. Demand CS has been awesome, but I read on the label that there is always a possibility of insects building a resistance to it. So I thought I would also use Termidor SC to treat the outer foundation and walls of my home, every so often. Two questions: Is this a good idea? Can I use the same hand pump sprayer for both Demand CS and Termidor SC at different times?


Termidor SC is applied only twice a year on the outside of the home depending on the rate used.  Rotating it often with the Demand CS would null the non repellent factor of the Termidor.  Most choose to use the Termidor outside and the Demand inside in cracks and crevices.  Resistance can take years to build up.

QOutside home foundation application frequency

QCan Demand CS be used in a wood deck?

QCan I spray my back patio off 24 hours after Demand CS was applied, or will it wash off the product?
Also does mopping wash it off?


If you plan to clean an area where you are going to spray a residual insecticide such as Demand CS, then it would be best to do your cleaning first and then apply the insecticide. This will not only ensure that you are spraying on the actual suface (rather than on top of dust/debris), but it will also prevent unecessary removal of your insecticide. Mopping or other abrasive cleaning will remove most if not all of your residual, so do these treatments before spraying for best results.

Keep in mind that Demand CS and other pyrethroids should not be sprayed over the entire surface of a deck or other hard surface. Keep to perimeter treatments and spot treatments where target insects are found.
