Organic Gardening Advice
Natural Insect (Pest) Control Ideas
One aspect of organic gardening is finding alternative ways to deal with insect problems (rather than resorting to the use of chemical products). The effects of something that seems so simple to us.. using insecticides to kill bothersome insects, are very far-reaching.
- The immediate consequence, is that the fruit, vegetables, and herbs that you eat and are feeding your family contain a residue of that same toxic chemical that you used to kill the insects with. (Yum! Would you like another serving?)
- Some of the insecticide stays within the soil in your garden, waiting to be soaked up into the fruits and vegetables for your family's crop in later years. The more you use, the greater the residue in the soil, and thus the greater the residue in your own food.
- Some of the chemical washes away with rainstorms, into either the streams/river systems, where they pollute the waters there - or into your storm sewer. Often, this water ends up at the water-treatment plant. The treatment plants processes don't always remove these chemicals and thus they're passed back to your family for consumption once again.
- Insecticides also can eliminate "good" or beneficial insects.
- Insecticides can affect more than just insects. Many of the beautiful birds we love to watch in our gardens, are affected very harshly by these chemicals. Sometimes, it kills or sickens the bird directly. Other times, it affects their reproductive process, such that attempts at offspring aren't successful.
Controlling insects through organic measures, while sometimes more time consuming, is a healthy and community focused way of gardening responsibly.
Here are some of our favorite Organic Gardening Insect Control Ideas:

Healthy plants are not generally prone to insect infestations. The best preventative (organic) measures you can take are: 1. prepare the soil properly for your crop, considering soil and growing requirements for that specific plant. 2. make sure any organic matter, compost or manure is well-rotted before using. 3. rotate your annual crops every season to a new location in your garden.
NOTE: Always wear protective gloves, glasses, etc. when using sprays that might irritate your skin. Also, only apply sprays to your plants in the morning when air temperatures are cooler, or you may risk burning your plants.
Goo
Use this mixture to trap insects. Mix equal parts of mineral oil, liquid soap, and petroleum jelly.
Garlic Tea Spray
Effective for most plant diseases. Naturally, the sooner you catch and treat the plant disease, the easier it is to cure. To make the Garlic Tea Concentrate: Puree 2 to 3 garlic cloves. Mix with 1 qt water, and blend again. Strain out the garlic, and add 1/8 tsp liquid soap. Store in an air-tight container. To use, mix 1 part garlic tea with 10 parts water. Apply with a spray bottle.
Herb Tea Spray
This is best used as a deterrent for insects (spray it on the leaves of plants most likely to get attacked, as preventative measure). Save fragrant clippings from your herb garden (the stronger smelling they are, the better!). Fill a gallon jug or bucket with water and place the clippings in the jug to brew (like you would with sun tea). Let it brew for about a week. Strain out the herbs and add 2 tbsp liquid soap. Keep in a spray bottle, so it's ready when you need it. (Try a Basil Tea spray for leaf-hoppers, aphids, cabbage loopers, mites or beetles!)
Pepper Sprays
Use as a general insect and pest (deer, raccoons, rabbits, etc) deterrent.
- Mix 2 tbsp hot (cayenne or hotter) pepper with 6 drops liquid soap and 1 gallon water. Store in a spray bottle for easy use.
- Mix ½ cup apple cider vinegar, 1 tsp hot pepper sauce, 1/8 tsp liquid soap. Shake well and put in a spray bottle.
Other Odds & Ends Ideas for Organic Insect Control:
Borage:
Aphid lions are attracted to borage. Aphid lions are one of the friendly insects in your garden, dining on many other pesty garden insects.
Canola oil:
Smothers insects
Cinnamon powder:
Is an antifungal and repels ants
Cornmeal:
If you have a problem with cutworms, try sprinkling cornmeal around the plants. They eat the cornmeal, but can't digest it.
Essential Oils:
Use 10 drops of a very fragrant essential oil like mint or pennyroyal mixed with 1/8 tsp liquid soap and 1 qt water. Use as a preventative measure, by spraying on the leaves of plants that are most likely to get attacked by insects.
Fireflies
Fireflies are very heavy eaters of some of the most pesty garden insects (larvae, mites, slugs, snails, cutworms, etc.). You can attract fireflies by leaving an area near your garden that's not mowed (and that isn't treated with chemicals!).
Petroleum Jelly
To keep ants from eating your plants, spread a thick layer of petroleum jelly (even Vicks will work!) around the plant's stem or trunk
White Flour:
If you have a problem with cabbage worms or grashoppers, go out in the morning while there is still dew on your plants. Sprinkle them with flour. Then the next day, wash off the flour and the dead bugs.
Helpful Little Critters:
Salamanders, toads, turtles and lizards all help your garden by making meals out of insects. Attract these garden friends by leaving small piles of rocks or wood for them to hide in.
Snakes
Most snakes are quite harmless and are even helpful in your garden, in that they eat insects and rodents!
Spiders:
As much as spiders give us "the creeps," they are so important in helping to keep the insect population under control in your garden. You can encourage spiders to patrol your garden, by building little shelters out of mounds of twigs or rocks. I've also heard of those who take terra cotta pots and turn them upside down in the garden, leaving them as "spider houses" around the garden.
Sugar
Sugar water sprayed on plants infected with aphids, scale, whiteflies or mites, can attract ladybird beetles (who will eat these pesty critters for you). Spray the sugar water onto the plants, but don't spray any ladybird beetles themselves.
Vinegar
A good common all-around gardening agent that fights fungus diseases, some insects, and kills weeds
