Is Demand CS Insecticide Concentrate by Syngenta Safe for Pets?

Should not contact wet surfaces; generally tolerated once dry

Syngenta's own consumer-safety material states dogs should not contact spray or surfaces still wet. Once dry, the diluted microencapsulated deposit has what the manufacturer describes as a favorable safety profile, but pyrethroid-class caution still applies.

Should not contact wet surfaces at all — keep off the dried deposit too

The manufacturer's own material explicitly says cats should not contact wet surfaces. Combined with cats' limited ability to metabolize any pyrethroid, and the fact that microencapsulation is designed to extend how long the dried deposit stays bioactive, cats should be kept off treated surfaces well beyond the initial dry time.

Keep off treated surfaces until dry and avoid repeated contact

Small-bodied pets have higher relative exposure per pound; the extended-residual microcapsule deposit means ongoing contact should be limited, not just the initial wet period.

▸Syngenta consumer-safety MSDS

Should not contact wet application; low dietary risk once dry

Syngenta's material states birds should not contact wet application. Dietary toxicity for this pyrethroid class is generally low, but keep cages away from spray mist during and shortly after application.
