Edit: Apparently this isn’t so obvious to people. Ok, let me explain:
No pesticide can be precisely targeted. You will always capture or kill more insects that are beneficial than are not. In the article it mentions that the sticky spray doesn’t capture bigger insects like bees. That’s certainly progress over other types of physical traps, but not all insects are very big. Key beneficials like lady bugs, green lacewings, various spiders, pirate bugs, etc are very small. They will be trapped by this spray. If it traps a thrip, it will trap those bugs (and the study abstract says this - “small anthropods”). This isn’t mentioned in the article but I can speak to this from personal experience farming. I’ve tried various options and the results are always the same - you may get rid of some thrips (and boy do I have thrips) but you also wipe out the insects that will eat the thrips and you end up in a kind of arms race. The more beneficials you kill the more pesticides you need.
