Technically it's still on topic and it's a good healthy discussion, which is always pleasant. We haven't gone into 3rd grade mode calling each other names. I'm actually genuinely interested in what's actually going on with the soap. Maybe you can explain what's going on. When I had the infestation in the tomato plants I read about this method all over the internet. I would knock the stink bugs off the leaves into a small bucket of soapy water, watch them struggle for 15-30 seconds or so, and stop moving. The larger ones were quite a challenge, but eventually they also went down. I did this with hundreds of stink bugs for several weeks. I thought about spraying the plants down with the soapy solution to encapsulate the bugs, but that would probably be detrimental to the leaves and fruit. I eventually gave up when I realize I couldn't win the war against them and the hornworm (an even more formidable opponent). So are you saying that the bugs aren't drowning, but actually dehydrating in the pool of water? I guess that's possible. I've seen stranger things happen.
Link1Link 2I'm not sure if this would be considered scientific enough, but here's articles for the University of Maryland Extension (Link 1) and Cornell University/Rockland County Extension (Link 2). Both articles specifically uses the word "drown". There's actually articles from quite a few extensions that use the word drown. That's what leads me to believe that the ultimate cause of death is asphyxiation. I've never ran across an article mentioning dehydration when relating to the soap method. Doesn't mean it doesn't exist, I've just never seen one. Maybe the idea of drowning is just a misnomer. Maybe what's going on is a combination of drowning and dehydration. I'm not trying to challenge you or downplay your experience or credentials in any way. I'm just interested in what's going on.
