Question 1

How does Syngenta Demand CS compare to other scorpion sprays?

Accepted Answer

Demand CS uses iCAP technology — a proprietary microencapsulation system where the active ingredient is enclosed in tiny polymer capsules that stick to surfaces and release slowly over time. This gives it a significantly longer residual than standard emulsifiable concentrates or wettable powders. In independent testing, Demand CS consistently outperforms competing products for scorpion control duration, which is why it remains the preferred choice of professional pest control companies in Arizona.

Question 2

How do I mix Syngenta Demand CS for scorpion control?

Accepted Answer

For scorpion control, mix 0.5–0.8 oz of Demand CS per gallon of water. For severe infestations, you can use up to 1 oz per gallon. Add the concentrate to water in a pump sprayer and mix gently. Apply to the exterior foundation, entry points, weep holes, and interior baseboards. One 8-oz bottle makes 8–16 gallons of finished spray, enough to treat a standard Arizona home multiple times.

Question 3

How long does Demand CS residual last in Arizona?

Accepted Answer

Outdoors in Arizona's intense sun and heat, Demand CS typically provides 30–60 days of residual protection. The iCAP technology extends this compared to standard formulations, but UV exposure and extreme temperatures still degrade the active ingredient over time. Indoor applications last 60–90 days. For year-round scorpion control in Arizona, plan on quarterly exterior treatments with monthly touch-ups during peak season.

Question 4

Is Demand CS safe to use around my family and pets?

Accepted Answer

Demand CS is safe when used as directed and allowed to dry completely. Keep people and pets out of treated areas until the spray has dried, typically 30–60 minutes. Once dry, the treated surface is safe for normal contact. The low-odor formula minimizes indoor air quality concerns. Lambda-cyhalothrin is highly toxic to fish and aquatic invertebrates, so avoid applying near ponds, pools, or drainage areas that lead to waterways.

Question 5

Can I use Demand CS to treat inside my walls for scorpions?

Accepted Answer

Demand CS can be applied to wall voids and attic spaces using a crack-and-crevice tip or a power duster. Scorpions often travel through wall voids and attic spaces in Arizona homes, so treating these areas can significantly reduce indoor scorpion activity. Apply to weep holes, expansion joints, and any gaps around pipes or conduits that penetrate walls. Combine with exterior perimeter treatments for comprehensive scorpion exclusion.
