One great way is liquid soap. You take one part liquid soap, and one part water and you put it on your plant. This will keep most bugs away. If the soap doesn’t work, I have another way: 1 bulb of garlic, 1 small onion, 1 tablespoon cayenne (red) pepper, 2 tablespoons liquid soap, and 1 quart water. Mix all the food ingredients and water. Then let it sit for about an hour, and then add the soap. Once all the foam goes away, you can put it in a spray bottle. It’s good for about two weeks if you put it in the refrigerator. This is a great natural, inexpensive insecticide and it works just as good as the store bought insecticide.

I used the onion, garlic, red pepper, soap and water recipe yesterday and it helped already! I didn't have any onions, so I used dried onion flakes. Today the grey bugs that were all over my Squash are gone!
