I kinda wish I had fungus gnats again, so I can test out a spray. Funny how they hide from me now days..
I got old bottles of oxidized free base liquid nicotine that are real peppery tasting, and rather use them somehow than throw it out. Pure clean nicotine is way less toxic than most the chemicals being used these days IMO.
I can easily measure out exact ratio's that are safe to handle, unlike all the crazy tobacco extraction recipes to make nicotine pest sprays out there. Most processed tobacco is nasty, and I wonder if the chemicals used in the process are actually what makes the sprays any good. I also wonder how the end product would test out, and what the difference between cigarette tobacco juice, or clean pharma grade nicotine based sprays would be, according to the tests.
I know for a fact I can wipe out gnats by literally coating them with vapor, but mainly also sucking all the moisture out of the coco/medium with a shop vac, then letting it dry for a few hours, and vaping out the entire pot full of medium\rootzone with peppermint + VG nicotine base makes them all crawl to the surface, and wriggle around and die. The flyers take off and go rub there eyeballs out until they die too. Then flush the pots and resume normal feeding, knowing it will slightly affect the plants, but they will bounce back. I haven't tested enough, but know it doesn't kill off the roots and the plants lived.
