How to Make Your Own Garden Pest Sprays

Is your garden really green? Sure, the color of much of the plants in the garden is green, but are you keeping the chemicals out and making it truly “green”?

There are many alternatives to chemical garden sprays that are just as effective in reducing disease and pests. The great thing about these concoctions is that they are safer for pets and other creatures that are beneficial to your garden. Natural garden remedies do tend to take a little more elbow grease but they are worth this extra effort.

The following spray will help keep unwanted insects away from your garden. Try it on your vegetables as well as on your roses to control aphids. Just a small warning – it will make you crave Italian food!

1. Bug Spray Concentrate

  • 3 unpeeled garlic heads (yes, that’s heads not cloves)
  • 3 oz liquid paraffin found in craft and/or hardware stores
  • 1 tablespoon grated oil-based soap (Ivory Snow is good)
  • 2 cups hot water

Crush the garlic heads and add to the paraffin in a small bowl and let stand for 24 hours. Melt the soap in hot water (do this in a pan or bowl that you will never use for cooking as the residue will stay with the pan and make everything taste like soap). Allow this mixture to cool and add to the garlic mixture. Mix well and strain into a glass jar. Store this mixture in the refrigerator. When ready to use dilute 4 tablespoons of the concentrate in 4 pints of water. Spray every two weeks or after heavy rain. The concentrate will last in the refrigerator for about 4 to 5 weeks.

The next spray will deter and kill whiteflies, mites, aphids and scale.

2. Murphy’s Spray

  • ¼ c Murphy’s Oil Soap
  • 1 gallon of water

Combine in a large container and transfer into a spray bottle to spray both the top and bottom of leaves and stems, but make sure you do this when the sun is not shining brightly or the leaves will burn (the soap attracts the sun’s rays). A good time to do this is on an overcast day or during dusk. Apply weekly or after heavy rain while the infestation continues. You can store what you don’t use in a dark, dry area.
