Garlic Fire Spray Experiment

I’m new to gardening; consequentially, I’m new to garden pests. I also plan on eating the vegetables in my new garden. That puts me in a predicament. I have to start thinking about pesticides, which are expensive, hazardous, and insect-specific.

If you are a newbie to gardening, it’s going to come faster than you think. You might be reading this because pests already caught you by surprise. If you are a veteran to gardening, you know this predicament. My broccoli seedlings are two weeks old, and tiny caterpillars have been eating them already.

So, after googling around a bit about organic and food-safe pesticides, I saw the names “Garlic Fire Spray” and “Garlic and Chili Fire spray.” I had everything except a good soap for the mix. And I’m filtering the batch as I write this.

The recipe calls for the following in a blender:

  • 2-3 Garlic Bulbs (~6-10 cloves per bulb)
  • 6 large or 12 small hot chili peppers
  • 1 T of vegetable oil
  • 3 squirts of liquid detergent
  • 7 cups of water (~2-3 cups in the blender for the mixing batch—the rest later)

After you blend everything, you filter the batch into a spray bottle, add the remaining water, and use it frequently.

I modified the ingredients a little, and this is what I’ll do different next time (if this stuff works).

  • ~27 Garlic Cloves
  • 14 Small Dry Chili Peppers (already had them in kitchen)
  • 1 T Canola Oil (approved by the EPA as a pesticide)
  • 3 squirts of No-Additive Liquid Dish Soap (some people debate about soaps or detergents, but the goal is to get it to stick to the plant and the safest soap should do the trick; furthermore, I kill fleas by dropping them in a cup with dish soap and water)
  •  2 Cups of Water

I’m using a funnel and a coffee filter to strain the batch into a glass jar. Honestly, this stuff smells intense. Subtract the soap, and this is a helluva baguette dip. It’s taking a bit to run it through the filter. The juice that’s coming through looks like melted beeswax, honey, and suds.

Check out the color of the end result. It’s the color of a heavy craft brew. This stuff could even offend the nose of a garlic lover.

If I make this again, I will wait to add the canola oil and the soap until I’ve filtered the batch. The soap is sudsy and the leftovers are oily. Kind of hard to get that through the filter. I used my tablespoon measure to press the last of the chunks through the funnel.

As I mess with plants and seedlings vis-à-vis concentration/dilution levels, I’ll post the results. In addition, I’m going to test this on the soil of more sensitive plants.

On a final note, some websites say to keep this on a shelf somewhere. My rule: if it’s made of organic matter, put it in the fridge with a warning label.
