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
  • Capsules protect active ingredient from UV rays, extreme pH, and porous surfaces

    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  Don't Waste $$ On Supermarket Insecticides and Exterminators
    By Alan in Shawnee, Kansas on 09/04/2017

    I purchased Demand CS for control of annoying spiders and ants in/around my house and basement. We used an exterminator at $100 per visit for a couple of years. I would have to tell him to put down adequate traps and insecticide to get reasonable control. The spiders and cobwebs would be back after a month. I wasn't pleased. So I purchased and used Demand CS as instructed. In two days I went to the basement and counted a dozen dead spiders on the floor. After four months, still no cobwebs. The residual effect is outstanding. I just treated again after 4 months. This will protect against spiders and pests throughout the winter. This product is very inexpensive. Using the recommended rate of 12ml per gallon on water. An 8 oz bottle should last me three years or more.

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 product will work best for roaches Demand CS or Demand SC?


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.

Here is a link to a great article that really goes into depth in explaining a roach control program:

QIs Demand CS effective on brown recluse spiders?


Demand CS would be a great choice for brown recluse spider control as well as general insect control. Brown Recluse spiders are very scary to have in your house, but they are no harder to get rid of than any other spider. The hardest part of getting rid of the brown recluse is finding them since they like to remain hidden. Demand CS would be a great choice for indoor and outdoor spider control. Spraying Demand CS will also help to get rid of the other insects (silverfish, sow bugs aka rollie pollies and millipedes) that spiders feed on and that will help to stop new spiders from moving inside. Indoors, spray around all baseboards, door frames, window frames, under appliances, in closets and storage rooms and in areas where utilities enter into the structure. Outdoors you should spray around the bottom of the foundation, on the ground adjacent to the foundation, door frames, window frames and places where the utilities enter into the structure.

QWill Demand CS work on chiggers when sprayed in a yard?


Yes, Demand CS is applied to lawns at the rate of 7ml per 1,000 sq ft. Treatments for chiggers should begin in May and could need to continue through the summer as new chiggers move into the area. Treating the entire lawn is of little benefit because chiggers avoid direct sunlight and normally will not infest areas that are mowed or otherwise well maintained. Focus treatment on the unkempt areas of the lawn and lawn edge. You can also use Demand CS to do a barrier treatment around the outside of your home and in your crawl space to stop pests from moving indoors.

QIs Demand CS the best to add to Talstar P?
I currently use Talstar P both inside and out, with decent results. I still have some small black flies, indoors. Maybe fungus gnats or a fruit fly, I'm not sure. Is this the right thing to mix with my Talstar?


No, it is not recommended that you mix two insecticides together. This would essentially be doubling up on the product and may cause the adverse effect.

A good option would be to use PT Alpine Pressurized Fly Bait in the area where you are having an issue. Apply inside all garbage receptacles, underneath garbage lids, inside recycling bins or receptacles, and other labeled areas that will help prevent flies from being a nuisance.

QWhat is the shelf life of a gallon of Demand CS working solution?
Is it okay to make up a gallon to have on hand when needed, or does it not last long in solution?


You should use diluted solution of Demand CS or other insecticide concentrates as soon as possible and within 24 hours. After this time, the active ingredient breaks down quickly in solution. Shelf life of the concentrate is 3-5 years when stored in a temperate environment out of direct sunlight.

QWhat is the mix rate for using Demand CS when using the Chapin Wet/Dry Hose End Sprayer for Japanese Beetles?
When using a Chapin Hose End sprayer connected to a water hose, what should I set the dial at in order to kill Japanese beetles?


When using Demand CS to treat Japanese Beetles, the mix rates vary depending if you are treating the lawn or ornamentals. Please refer to the product label for application instructions. 

Lawn Mix Rates: 3.4 - 7ml (0.1 to 0.2 fl oz) per 1,000 square feet / 5-10 fl per acre 

Ornamental Rates: 0.4 - 1.3ml (1.5 to 5fl oz) used in 25 gallons of water. 

For spot treatments, use 0.5 fl oz Demand CS Insecticide per 1–2 1/2 gal of water.

Since water is acting as the carrier, each treatment and the amount of water that will be used is specific to the individual treatment. Please take a moment to review our How to use the Chapin Wet or Dry Hose End Sprayer Video for tips on how to set the dial for this sprayer.
