I just wrote this in another thread so I'll modify here.
For decades out at my folks' house, I made up a garlic spray that I've often used as a deterrent for slugs on hostas. Basically, the really cheap powdered garlic at several dollar type stores, and water. Buy a few canisters as they are cheap. I use anywhere from 1/2 to 3/4 of a canister for my sprayer tank. Let steep for a few days, add a small amount of dish soap to break the water tension on the waxy cuticle of the leaf, and load into a sprayer that I only use for this stuff. I am hesitant to use on the squashes because I like my squash bees. Likewise any plant in which I'm trying to encourage bees/butterflies. If you do use the garlic spray for anything, know that you must spray top and bottom surfaces of leaves. If it rains well, you'll need to reapply. Works on flea beetles on greens and cole crops as well. I'd be interested to hear from anyone who tries it...especially if it didn't work on a specific plant and/or pest.
