It doesn't matter what pest it is, Spinosad will slaughter any common pest 9 out of 10 times in 1 application per/directions on bottle.
And when growing outside it will kill any bees or beneficial pollinators that come in contact with it within a day of its use or longer. Also, from the image posted by the OP of the product they asked about you can see that they're in Australia. They have also discovered that WFT "Western Flower Thrips have developed a resistance to spinosad. Most likely from overuse and indiscriminate spraying of the insecticide. So it's not a certainty that spinosad will have any effect on thrips due to some developing a resistance to it.
Spinosad is also banned for use in commercial cannabis grow operations in half a dozen states and is unavailable for sale in Canada and several European countries with more likely to halt its use.
If it kills bees don't use it outdoors please. There are other just as effective methods that are not a death sentence for bees or other pollinators that come into contact with it. It's time to be more concerned about the planet than some cannabis plants. We're destroying the planet. If we haven't already we all need to do everything in our power to make sure we don't reach the point of no return.
"Spinosad has been widely used in Australia to control western flower thrips Frankliniella occidentalis (Pergande) but spinosad usefulness is now compromised by resistance."
Spinosad has been widely used in Australia to control western flower thrips Frankliniella occidentalis (Pergande) but spinosad usefulness is now compromised by resistance. Here we studied a highly spinosad resistant strain of F. occidentalis to explore if esterases had a role in spinosad...

"Resistance to spinosad Despite the initial success of spinosad against WFT, studies revealed that WFT appeared to quickly adapt to, and withstand, the effects of this selective pesticide. A 2005 study showed that spinosad resistance levels were around 97 per cent in a single property that relied heavily on the product. Reasons for this might include an over-reliance on spinosad alone, as well as use of the pesticide in ways that may impede the efficacy of IPM programs."
