Demand CS

Availability: In stock

Demand CS, by Syngenta is a general multi-purpose insecticide. Demand CS is a pyrethroid insecticide in a microencapsulated water-based formulation. This microencapsulation not only gives you a longer residual, but there is no stain. Demand CS can be applied at low concentrations, so you have less pesticide exposure. Demand CS contains Lambda-Cyhalothrin 9.7 as an active ingredient. We recommend looking at LambdaStar UltraCap 9.7 or Cyzmic CS if you like this product. These two products use the same active ingredient and are just as effective but at a much lower cost.

Demand CS - Improved Pyrethroid

Compared to older pyrethroid materials that have been used for many years with declining results, Demand CS is up to 200 times more active on flies and other animal health pests allowing lower rates. Demand CS is designed not only to work better, but to work longer.

Ideal Perimeter Protection

As an advanced, general purpose insecticide Demand CS, solves the difficult pest control problems in a variety of residential and commercial sites.

The active ingredient in Demand CS is released from the microencapsulated capsules. The mode of action comes from the insect coming in direct contact with the insect to the cuticle of the insect. Sometimes the insect will ingest it as it preens itself such as roaches.

Application Versatility

Demand CS can be used outdoors for perimeter applications and barrier treatments or indoors for a wide variety of pest. Demand CS can be used for both clean-out and maintenance. It is labeled for use in food handling establishments and within food serving areas. Demand CS can be used on porous and non-porous surfaces without stain.

Works great on mosquitoes
I have used this product for two years now for mosquitoes. Before use they have been so bad that you can't stay outside with out repellent spray. After spraying Demand CS they are gone. We live in Michigan and both years I've only had to use it twice. I'd highly recommend it.

Works Great!
This stuff really worked when my exterminator used it, so I bought it myself. Even with the lowest mixture it seems to work great. Just have to read directions and find the right mixture for your pest problem. Definitely worth the money and cheaper than paying someone else.

Great product
Paying $300+ a year for monthly bug spray was out of the question. I finally asked what they used and was told Demand CS. Looked it up online and found it here. Now when a salesman comes to my door I tell them what I use and they are surprised. Stops their sales pitch cold. I've been using it for 6-7 years and spray once outside the perimeter of the home and around windows in the spring, summer and fall. Works wonderfully! Worth every cent.

It's the first gun I grab
I bought the quart and received it on 5/24/2007. ( I dated the bottle) I was originally having the exterminator come to the house and spray, but the cost was starting to eat into my discretionary income. The last time I hired the exterminator he ended up using the last bit in his truck mounted machine gun! I asked him if I could have the bottle and then I did what every good American would do.....I did a search online for a supplier! I found this company and am thankful they have saved me many many $$$! Thank you! And oh by the way, I came back today to order any quart! It's been sitting on my basement shelf for 8 years and still kills the bugs.

I use this for scorpion and crickets in Phoenix area and is great.
I used to pay $50.00 every 4 weeks, now I spray every 8 to 10 weeks. It is bet expensive but is the best.

Great Product!
I purchased the Demand and one gallon sprayer. They both work great. A little goes a long way.
Review by Ed / (Posted on 7/26/2014)
As a professional pest control technician I relied on Demand CS as my go to product when I was treating commercial buildings. It was a bit expensive to treat residential homes on a full time basis. But for the homeowner this product is ideal. It just plain works.
Review by Mick / (Posted on 6/25/2014)
Very good product, good price.
I have used Demand CS for several years after learning that this is what the local professionals use in this area.

It is easy to use and lasts a long time.

DIY Pest Control provides the product at a good price.

product works as advertised
very happy with the results of product; no odor; helpfulness of employees, and prompt shipping.

None better against pests
Phil Pelletierri, former UW-Madison entomologist, originally recommended this to me 6 years ago. Demand CS controls pest populations around the house interior and exterior. Comes as a concentrate and mixes easily. A gallon of mix lasts quite a while, so the bottle of concentrate also lasts a long time.

Very effective for ants and earwigs - the only two pests which bother us. I have been using it for about 10 years
Review by pete / (Posted on 4/16/2014)
i love it it works like magic
i used to pay for a company to come every month and spray and they used to charge me $30 every single month since i knew about this website i been using the Demand CS, and omg it kills every thing out side and inside my home and i only spry every three months once so if you buy one it will last you for a whole year, it saved me a whole money a lot and since my state CA we can not buy this product from a store it illegal, so we have to hire a pest control company, but this sep site saves me so much money I LOVE IT, THANK YOU VERY MUCH AND KEEP UP THE GOOD WORK.

great for fleas !!
I live in South Florida and the fleas are so bad year round. I sprayed Demand outside in the dogs area, including his house, (I moved him first) and It worked great !! He didn't have a flea on him or around him for more than 6 months ! What a savings compared to buying Confortis or Frontline for fleas on the dog! The Demand killed the fleas on the ground before they could jump on him. Also sprayed the perimeter of my house and I didn't see one palmetto bug after !!!

Killed Some Scorpions
Sprayed all around the foundation and along cracks. I've found some dead scorpions, but I'm not sure they're all dying we'll see. They scare the beejezus out of me.

Armageddon for Bugs
Oh my, I love this stuff. I moved into a new home that had an earwig infestation, along with a few indoor centipedes (ugh) Well, I went nuclear winter on my basement and perimeter of the house and dead bugs were everywhere. I highly recommend and also suggest getting the sprayer, it works great.
Review by Missy / (Posted on 9/16/2012)
I started using Demand CS one year after moving to Florida from NYC. A friend of mine told me about the product and where to get it. I ordered my first bottle in the spring of 2004 and have been using it ever since. I spray a 2-4 foot thick perimeter about 3 feet from the house. I find all kinds of bugs on their backs dead within 1-2 feet from the house all the time. I wish they had a product for the in-laws. :-)

This Is The Best
The price is a bit high but I have been using it for 4 years with unbelievable results. I have a very wooded property which butts up to wetlands and thus have quite the mosquito problem. My son is unfortunately allergic to the bite of a mosquito. This is the only product I have found thus far which successfully eliminates the mosquito population. I own two mosquito magnets, a fogger and have tried countless numbers of 'professional grade' applications which claim to be cheaper and as effective. I always end up having to come back to Demand CS... as I am now. There is NO SUBSTITUE!!! This works longer and more thoroughly than ANY other product out there currently. I have recommended this product to several other people who have had issues controlling mosquitos and they have came back asking why I have kept this secret.

Scorpions controlled
I've been using this for the past two years here in Arizona. I apply it every 3 months outside and have not seen a scorpion inside my house since using it. At first application, bugs were dead several feet away from where I sprayed...never even making it to the garage.

Gets rid of spiders
Sprayed the outside of our log home on the lake in the spring for spiders. Did not have a problem with spiders, or webs all summer. Sprayed once more in the fall. Great results.

Knocks em out GOOD
Had an 8 oz bottle for two years and it worked well each and every time. Application was easy and the stuff really killed the bugs, small pests, and especially the roaches. Was not highly effective for ants. The comment was made that for $40 no pest control service was ever needed again. We got at least three months per application. The first application was the best seeing dead bugs everywhere the next day. Looked like a bug bomb went off outside. Used inside and outside pound for pound it keep us bug free. -- Savannah, Ga
