Well, neither did I until I looked it up, but I found it pretty interesting.



Like the fact that hot peppers, yellow onions, a head of garlic, (or 10-15 individual cloves if that's all you have) & citronella are the ingredients for the base of an All-Purpose Anti-Pest Repellant. If you want to make the spray repel a specific pest, you need to add other ingredients that that specific pest dislikes into the mix.



Evidently, if you add rue, scaredy-cat plant, & lemon thyme to this base, the result will ward off cats like the plague.
