Insect Repellent

Mixing the ingredients together in water.

Insecticides are used widely throughout Thailand.  They are very effective too!  Almost too effective.  This can be attested to by the workers who come home sick after spraying it on the fields they tend.  In response to this, we have chosen to brew a natural insect deterrent both as a means to protect our workers and so that we do not damage our soil. A large majority of insects are easily repelled with the use of noxious odors (from their perspective, we happen to think that citronella smells quite nice).  Our recipe consists of crops that can either easily be grown on our farm or are found year-round at the market. It is important to note that the recipe is not dependent on all ingredients being present, although the inclusion of them all will increase its effectiveness.

Repellent Ingredients

  • 1kg Citronella
  • 1kg Golangal
  • 1kg Bitter Bush Flowers
  • 1kg Fresh Chilis (more spicy = better)
  • 15 Liters Water

Finished Product: just let it sit for one week before using.

Thoroughly chop all solid ingredients and add into a 20 Liter or larger container with a lid. (Note: be sure to use gloves, long sleeves and a face mask when chopping the chili.)  Cover the ingredients with the water.  You can use a large rock or brick to keep ingredients submerged in water.  This recipe works primarily through osmosis and will be ready for use after one week.  To use, dilute the liquid from your product in water at a ratio of 1:10. This should be sprayed directly on the leaves of your plants.  Protective clothing is recommended due to the high levels of capsicum from the chilis.

Note: Feel free to experiment with other additives. For example, we plant marigolds on our farm for its repellent properties. Many other such plants would be a welcome addition to this recipe.
