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

By Eric in Scottsdale, AZ on 06/09/2009
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!

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!!!

Ants, crickets, and roaches no more...
By Gregory in Tempe, AZ on 04/15/2009
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!!!

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.
I will buy this for life!!
By Whitney in Gulf Breeze, FL on 03/19/2017
This stuff is amazing. After we moved to Florida I thought we were going to have to move back north because of the Palmetto bugs (huge). I ordered this on a prayer and thank goodness it works like a charm. I find them dead all around the outside of the house and on the off chance I find them dead inside, you can tell they didn't make it far. I've also found dead spiders all around as well as silver fish and milipedes...I'm sure it's gotten to many other bugs that I will remain blissfully unaware of. I will not pay for someone else to do my pest control (of this manner, anyway) ever again. I can also tell the bottle is going to last a very long time! Seriously SO THANKFUL!
By Aaron in Charles town WV on 03/10/2017
We use this product a lot, it does seem to work pretty well but the only issue is that it clumps up a lot during large amounts of use in the filter of the B&G and also the power sprayer I think we have used this chemical a bit too much because it definitely doesn't do well on spiders as much as it used to thanks
Thank you for your comments! Yes, if you are using a B&G sprayer with encapsulated or wettable powder formulations, then you will need to clean the mesh screen fairly frequently. You can always rotate with a different active ingredient and/or mode of action. Suspend Polyzone is a new formulation that you may want to consider for residual cap protection: http://www.domyownpestcontrol.com/suspend-polyzone-p-2455.html We appreciate your comments and your business!
By Sherrill in Sandia Park on 03/08/2017
I have used this product for many years. I spray inside and out and watch the bugs just die. I live in the mountains so I have a ton of insects trying to move in on me. I do spray twice a season...about 2 months apart. No insects have a chance once you spray this insecticide.

Effective Scorpion Killer
By Darrin in Scottsdale Arizona on 03/06/2017
I use this product as the result of a scorpion infestation on my 1 acre horse property located in Scottsdale AZ that I recently purchased. Using Demand CS as a part of an overall strategy to decrease the level of scorpion activity (removal of debris, sealing house, insecticide and black light hunting) has proven, from my experience, to be effective so far. Let me be clear, there is no secret sauce available to fully eliminate scorpions. They do not die like roaches and require constant efforts to ensure they trail away from your property and not towards it. I use Demand CS and ExciteR combined at dusk during new moon phases each month to actively kill these satanic beings. I spray in every crack and crevice I can find on the property, wait an hour or so and then go on a black light hunt. Usually, I will find live (and pissed), dead and/or dying scorpions around the property after this treatment. I use Terra spray to contact kill those that are not dead (usually the larger adults take longer). Next evening, I find more dead and dying, which tells me this product has a residual effect. I will make my final judgement on this product after the summer months pass but to this point, I would recommend Demand CS.
Saved money Elimnated spiders
By Hayes in Shoals Creek Alabama on 01/30/2017
Long sad story. I had a black widow and brown recluse abatement done before I began a remodel. Worked fine. When I was about to move in 18 months later they were back. I used a different company, from the start they had to come back Twice and after 4 treatments I still had spiders and bugs. One demand CS treatment and I have dead spiders and new webs anywhere. I created an outside barrier and. Even took out some fire ant mounds.
By Clifford in Madera, Ca. on 01/25/2017
This product is what you need to utilize if you want your house, inside and outside, to be bug and spider free! It is long lasting and safe for human and animal traffic. Just follow the directions and the results will be super satisfying, and you can take that to the bank!
By Roger in The Villages, FL on 12/26/2016
GREAT product with a fair price and fast shipping
By Alan in Flagstaff, Arizona on 12/17/2016
Great product for a fair price. It has virtually eliminated spiders and ants around and in the house. I also used it on aspen trees to kill oyster scale and it works great. As you know scale is very hard to kill unless you inject your trees. I am having good luck spraying it on the tree and on the ground around it in early spring before leafing and after leaves fall in the fall.

FINALLY - - ONE THAT WORKS
By Diane in Bradenton, Florida on 11/19/2016
I was infested with bed bugs, tried many things, a friend told me about DEMAND CS he said local pest control companies used it. I bought it and after 2 applications - every 4 weeks, I sprayed my 400 sq. ft. trailer, it is free of them. I HIGHLY recommend this amazing product.
By Gary in Florida on 10/24/2016
Have had exceptionally good luck here in Florida using Demand CS. When we leave in May and come back in Sept we come back to a bug-free home. We use the product again upon return and feel it is the best product out there to keep us bug free.

Ask a Question
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.

09/15/2016 Dave from Winnemucca, Nv
QThe ph of my water is 7.5 do I need to use a buffering agent when mixing with Demand CS?
It specifies a ph of 5 to 7 in the tank mixing Instructions (Turf and Ornamental Dilutions) on the product label. I use the product for perimeter treatments on the outside and inside baseboards of structures.

QWill Demand CS kill Harvester Ants?
They make a bare spot in the yard.
A Demand CS will kill ants that have come into contact with the areas treated with the product but it will not reach the nesting locations. Harvester ants should be left alone if they are not a direct threat or nuisance. They provide food for many animals, and also help distribute grass seed, and are overall beneficial. However, if control becomes necessary, you can easily get rid of harvester ants using the right professional products.Granular ant baits are the best choice to control harvester ants. Nearly any granular ant bait will work, but look for those labeled for use on harvester ants.Products with abamectin, like Advance 375A Select Granular Ant Bait, bifenthrin, like Talstar PL Granules and hydramethylnon, like Maxforce Complete Granular Bait, among many others, will all be effective against harvester ants. Always follow the label instructions carefully, but 2-5 tablespoons of granular bait scattered over the colony’s central opening should be sufficient to control the colony. For non-chemical control, destroy nests and habitat with regular mowing and other lawn maintenance.

QDose Demand CS kill bed bug eggs?
A Demand CS would not kill bed bug eggs as it is not a contact kill. However Bedlam and Bedlam Plus are labeled to kill both Bed Bugs and their eggs. You should note that even products that are labeled to kill bedbug eggs are not able to kill 100% of the eggs and you will still be required to do follow up treatments every 7-10 days until no further evidence (bites, blood stains, cast skins, fecal deposits) of bedbugs is noticed.

QWhat to use to measure Demand CS for spiders for 1 gal applicator?
A The bottle for Demand CS has a measuring chamber on it to measure out the rate you need to use per gallon. For spiders you would use 0.4 to 0.8 fl oz per gallon of water as directed on the product label. You would squeeze the bottle to get the needed amount into the chamber then pour into your sprayer.
