Homemade Organic Pesticides


No one likes aphids, slugs and other pests invading their garden. But you might not want to use things that endanger the health of your family and pets just to get rid of these creatures. A few simple ingredients you might have in your home can help you control pests in your garden without using harsh chemicals. While you can buy organic pesticides, you can also make them at home and save some money.

Step 1

Buy a few large spray bottles. Your local hardware store carries them. Plan to use a separate one for each homemade organic pesticide recipe you try.

Step 2

Boil some water. Mix with a chopped orange peel and one teaspoon liquid dish soap in your spray bottle. Allow this mixture to rest for at least 24 hours before spraying on plants.

Step 3

Puree one onion, three to four cayenne peppers and an entire head of garlic in your food processor or mince finely by hand. Steep this mixture overnight in a gallon of water inside a bucket. Strain the liquid into your spray bottle and apply to insect infestations as needed.

Step 4

Mix a few cups of chopped cayenne peppers with a chopped fresh horseradish root. Boil a quart of water and steep the peppers and horseradish in it. Strain the liquid into your spray bottle and use on insect infestations as needed.

Step 5

Mix one tablespoon liquid dish soap with one cup of vegetable oil. Spray on plants as a preventive measure. Respray after it rains or once a week.

Tips and Warnings

  • Some homemade pesticide recipes call for the use of loose tobacco. While this can be effective on certain pests, it is deadly to plants in the tomato and potato families. Any contact with tobacco, even if it's just from a smoker touching some tomato leaves as they walk by the plant, can kill these plants easily.
