Sooo… it only took TWO YEARS, but I finally tested @ClutchLinkey 's catnip mosquito repellent. I steeped last year’s catnip harvest in rubbing alcohol for about 2 months, strained it, and gave it a go undiluted. The cats went nuts! Joey tried to eat my arm, Cirrus went catatonic, and the two big girls got slappy with Joey because he was in their way. No idea yet if it repels Alabama mosquitos because I had to wash it off to stop the cat mob. Also, does isopropyl alcohol leave a residue once it evaporates that the beasties shouldn’t have?
Anyway, I’ll test it again, applying it outside next time, for mosquito efficacy soon, and maybe attract all the neighborhood strays in the process. Science! (kinda)
