Keep those little bugs away from your garden with this homemade organic aphid killer:

• Purée three or four jalapeño peppers, three cloves of garlic, and 1 quart of water.
• Strain the mixture and use it as a spray.

OR

• Blend ½ cup of aphid bodies with two cups of water.  (You can also use infested leaves to avoid gathering bugs by hand).
• Strain and spray on the plants.
