If these surfactants cause harm to other insects, it would be safe to classify them as insecticides themselves. Then you've just got a new type of insecticide, and need to demonstrate (a) precision, (b) recall, and (c) cost-effectiveness vs. all the other existing insecticides.
Surfactants attack the waxy layer that insects use to breathe, they’ve been very effective at killing them for a long time. The classic fruit fly trap of soap in vinegar uses this effect.
There’s a lot of soaps with a long history of being used in the environment, but like they do have a mechanical effect. Probably not great to douse plants with them.
The biggest challenge I see is they’re not really persistent like permethrin — you need to spray the mosquitoes with the surfactant. That limits application as people will complain about like a fogger truck that makes them a little soapy.
You can't really "develop a resistance" to something that is fundamental to your genetic identity. That's like saying "what if humans developed a resistance to being dunked in vats of acid?"
b) it's just soapy water, we understand soap quite well.
Stop thinking like an administrator and think back to your high school science class.
