Demand CS Insecticide — Lambda-Cyhalothrin 9.7%, 8 oz
Pesticide — read label before use
Demand CS is a professional-grade insecticide concentrate. Always read and follow label directions. Keep people and pets off treated areas until dry. Avoid application near water bodies, storm drains, and pollinator habitats.
Why we recommend this
Demand CS is the gold standard for micro-encapsulated perimeter insecticides. Syngenta's iCAP technology gives it a longer, more consistent residual than standard liquid concentrates — and it dries odorless, making it ideal for indoor use too. For Arizona homeowners dealing with scorpions, ants, or cockroaches, this is the product we'd choose for quarterly perimeter protection.

iCAP Micro-Encapsulation Technology
Syngenta's proprietary iCAP capsule suspension formula creates a time-release barrier — capsules adhere to pest bodies and surfaces, delivering extended residual protection far beyond standard liquid concentrates.

Highly effective pyrethroid that disrupts insect nervous systems on contact. Proven performance against scorpions, ants, cockroaches, spiders, and dozens of other common pests.
Up to 90-Day Residual

Labeled for scorpions, ants, cockroaches, spiders, fleas, ticks, wasps, bed bugs, mosquitoes, and over 30 other household and structural pests.

The best perimeter spray I have ever used
I've tried Demon Max, Talstar, and several others over the years. Demand CS is in a different class. The micro-encapsulation keeps it working longer than anything else I've used. Spray the perimeter every 90 days and I have zero pest issues. Scorpions, ants, spiders — all gone.
Pest Control Tech
This is what the industry uses — for good reason
Demand CS is a staple in professional pest control programs. The iCAP technology is genuinely superior to standard liquid concentrates. It sticks to surfaces and pest bodies better, lasts longer, and performs consistently even in hot Arizona summers. If you want what the pros use, this is it.
Tucson Homeowner
Solved a bark scorpion problem completely
Had bark scorpions getting into the house regularly. Started doing quarterly perimeter treatments with Demand CS and the problem stopped within two weeks. Going on 18 months now with zero scorpions inside. The 8oz bottle makes a ton of finished spray — very economical.
