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.

SPECIAL DEAL!! Purchase Cyonara 9.7 (same active ingredient for less).

Active Ingredient: Lambda-Cyhalothrin - 9.7%

DESCRIPTION: 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.

USE: 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.

5 of 5 Stars  Excellent product
By Eric Parpart on June 9, 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!

5 of 5 Stars  Ants, crickets, and roaches no more...
By Gregory Beers on April 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!!!

By Steve from Bakersfield, CA on September 4, 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.

When we moved into our house a few years ago we had a major cockroach problem outside around our jasmine-covered arbor and deck. Since using Demand CS the problem is NON-EXISTENT. I haven't even seen a dead roach in almost 2 years. Absolutely love the product.

Demand CS is the best thing I have ever used for the control of bugs indoors. I am in pest control and use this product daily and receive only positive feedback from all the customers. It works extremely well and customers love how it has no odor.

5 of 5 Stars  Works as advertised
By Tom on April 23, 2009
I bought Demand CS because we get Yellow Sac spiders in our house and I was concerned about the safety of my children. Yellow Sac spiders are an aggressive night hunter which are probably more dangerous than the Brown Recluse. I applied Demand to the outside of the house as a barrier. This stuff is simply amazing. It's like a hand came up and wiped the side of the house of insects. Oh, you'll see a spider, drunkenly, walking around. Keep watching him because he's already dead and doesn't know it. Works completely as advertised with just the slightest hint of an odor when applied and none after it dries. Highly recommended.

I had a problem with crickets and spiders. Within a week after I first applied Demand CS I quit hearing and seeing crickets around my house. I also have noticed that there are not any new spider webs.

This product is the best! I've tried every brand of insecticide from Home Depot and nothing can compare to Demand CS. Within two days of spraying I found 8 dead spiders and 3 crickets in our garage. If you want to control spiders in your home I highly recommend Demand CS.

ask a question about this product


I've heard that Demand CS will stop the fall invasion of the Chinese Beetle into our buildings. Is this true?
A Demand CS is labeled for a variety of insects, including the Asian Beetle. 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, and follow the instructions on the label, which is on the product and on our website. Good Luck!

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?
A 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. 

When spraying a tree for elm beetles that is next to my pond do I need to worry about the over spray of Demand CS hurting my fish?
A Yes, Demand CS like any other insecticide can be very lethal to fish.  It would be advised to apply the product on a day that is not windy, and possibly even holding up a sheet of plastic on the other side of where you are spraying to protect overspray from going towards the pond.  Also, apply on a day when it is not going to rain so the product has time to dry and bond to its surface so it does not run off.

Why does the label advise you that the treatment for fleas is "for outdoors only?" I want to get rid of fleas inside my house. If Demand CS works outside for fleas, why wouldn't it work inside for fleas while you were treating for other types of pests (e.g. roaches). Should I use a different product for fleas...I was hoping to find a single product for everything. Any thoughts?
A Demand CS is an excellent product for fleas, but the reason it is labeled for outside use only is because Demand CS is labeled to spray on the yard and large areas outside.  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 fleas.  Fleas can be in your carpet, on sofas, and on other areas where you cannot spray Demand CS because it is not labeled to be applied as a space spray or on areas that you come in contact with like your couch, chairs, pet bedding, etc.  We do have products that are labeled for fleas and for indoors and these products work very well and more effectively for fleas inside the home.  Our most popular flea control products come in our Flea Control Kit.  It has a very high success rate when used properly and is safe to use indoors around children and pets.
