I just use diluted IPA in a spray bottle. Kills almost all bugs near instantly and it's relatively safe and very cheap.
Due to the coronavirus i got into making my own IPA sanitizer spray with mint extract (careful, it can kill you, it's basically concentrated aspirin). 65-70% IPA by volume and 30-40 droplets of mint extract. Since i only sanitize my hands once or twice a day anymore i mostly use the spray for flying insects and roaches that manage to get past my cats.
Neither of those contains any acetylsalicylic acid (aspirin) as far as I know / can research.
To the best of my recollection, the "aspirin" part was comparing what a high dosage/overdose was like. I apologize for making the inference that it was "like" aspirin.
All i can find now is that menthol is potentially the dangerous part in concentrated mint oils - however i don't remember menthol being mentioned. I'm also used to claims of "misremembering" details from a half decade or more ago, and have since began screenshotting webpages with potentially controversial information, as well as saving and organizing all pdfs for studies i read, that are linked from news articles or social media. Hopefully situations like this one occur less frequently!
