Insecticides made by a soil bacterium (spinosad) or modified from its spinosyns (spinetoram). They act on insect nerves.

Watched ingredients get highlighted on every product panel you open.

Where it comes from
Fermentation of the soil bacterium Saccharopolyspora spinosa; spinetoram is then modified chemically.
Why it's in the product
The insecticide in some spot-ons.
Safety and toxicity
Flagged as a pesticide active, like every active in this aisle: the flag says what the ingredient is, not that it is riskier than the rest. Follow the label's species, weight band and directions.

We make the longer argument about this one on the pesticide actives evidence page.
