Demand CS is a professional-grade insecticide that provides immediate and long-term pest control. It contains 9.7% lambda-cyhalothrin, a synthetic pyrethroid that kills a broad spectrum of pests on contact or through ingestion, and an innovative microencapsulation technology formulation.
Demand CS uses iCAP™ technology, a microencapsulation process that suspends thousands of capsules containing the lambda-cyhalothrin active ingredient. When pests encounter treated surfaces, these capsules break open on impact or are absorbed through the exoskeleton, killing insects quickly. The varying capsule sizes ensure some release immediately, while others provide long-lasting residual control for up to 90 days. Whether you're dealing with ants inside your kitchen, mosquitoes around your lawn, or spiders in your garage, Demand CS works quickly and keeps working longer than traditional insecticides.
Kills over 30 pests, including mosquitoes, ants, spiders, and cockroaches.
Advanced microencapsulated technology provides long-lasting residual control for up to 90 days with extended protection on treated surfaces.
Virtually no odor and non-staining, ideal for indoor use.
Safe for use around pets and people once dry.
Economic mixing rate. One quart makes up to 160 gallons of solution.
Protects active ingredients from UV exposure, pH extremes, and porous surfaces.
Diluted solution resists settling and ensures consistent application.
Compatible with most insecticides, IGRs, and tank additives. Always add Demand CS last when mixing.

Indoor Applications
Use Demand CS only as a crack and crevice treatment indoors. Reapply every 21 days if needed.
Apply along baseboards, behind appliances, around plumbing entry points, inside wall voids, and in other pest hiding spots.
Do not apply to exposed surfaces or areas with food contact.
Always keep children and pets out of the treated area until the spray has dried completely.
Foam use: Demand CS may be converted into foam for the treatment of voids in walls and structural areas.
For bed bug control:
Mix at 0.2–0.4 fl. oz. per gallon of water
Apply only to cracks and crevices
Do not apply to mattresses, bedding, or furniture where people sit or lie down
Outdoor Applications
Apply Demand CS along the building foundation and around entry points such as doors, windows, vents, eaves, and utility openings for outdoor pest control.
Demand CS is also effective for use on lawns, shrubs, and ornamental plants where pests rest or breed.
Avoid treating surfaces recently exposed to residual insecticides to ensure maximum product effectiveness.
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.
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.
Application Rates (Mixing Ratios)
Mix the following amount of Demand CS per 1 gallon of water, depending on the level of infestation:
0.2 fl. oz. (6 mL) – 0.015% dilution
For light infestations, general maintenance, and common crawling pests
0.4 fl. oz. (12 mL) – 0.03% dilution
For moderate infestations
0.8 fl. oz. (24 mL) – 0.06% dilution
For heavy infestations, clean-out treatments, or control of spiders, scorpions, etc.
Infestation Levels & Product Yield
8 oz. bottle yields 10-40 gallons of finished spray solution, depending on dilution rate
32 oz. (quart) bottle yields 40-160 gallons of finished spray solution
Product Coverage:
At the lowest rate (0.2 fl. oz./gallon), a 32 oz. bottle treats up to 160,000 sq. ft.
Higher rates reduce total gallons accordingly for stronger infestations
Use a hand pump sprayer: A 1-gallon pump sprayer offers the best control for precise applications both indoors (crack and crevice) and outdoors (perimeter and foundation).
Keep children and pets safe: After application, wait at least 30 minutes before allowing children or pets to re-enter treated indoor areas. Always allow surfaces to fully dry.
Plan around the weather: For outdoor applications, apply when rain is not expected for at least 24 hours. This ensures Demand CS adheres to treated surfaces for maximum residual effect. Some turf or ornamental applications may benefit from light irrigation—check the label for guidance.
Tank mixing tip: If mixing with other insecticides or products, add Demand CS last to the spray tank to ensure proper dilution and stability.
Boost with an insect growth regulator (IGR): For complete life-cycle control of pests like fleas, use Demand CS in combination with NyGuard IGR or a similar IGR product. This helps eliminate both adults and immature stages.
Storage matters: Store Demand CS in a cool, dry place, away from direct sunlight and extreme temperatures, to maintain product integrity and shelf life.
Trusted by pest control professionals and homeowners alike, Demand CS Insecticide offers unmatched residual pest control, flexibility in application, and effectiveness across a wide range of environments. Whether you're treating a backyard or a commercial facility, Demand CS delivers consistent, reliable pest protection.

Excellent product
By Eric 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!

Great stuff!!
By Lauren on 04/29/2010
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!!!

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.

Ants, crickets, and roaches no more...
By Gregory 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!!!

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?

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?
