Chrysanthemum Flower Spray

Certain species of Chrysanthemums, such as the dalmation mum (seen on the right) contain a chemical compound called pyrethrum. This chemical has been in commercial use as an insecticide for over a hundred years.

These compounds affect the nervous system of insect resulting in death. It has also been shown to repel insects but does not remain on the plant long and actually break down in sunlight.

This means any insecticide containing pyrethrums need to be applied frequently until all signs of infestation are gone. It is beneficial in that you can be sure that no harmful buildup of poisons has accumulated on your plants.

To make Chrysanthemum Flower Spray you will need:

  • 2 cups of dried chrysanthemum flowers
  • 4 cups of filtered water
  • Cheese cloth or fine strainer
  • Spray bottle

Where to start:

  1. Start by crushing the dried flowers
  2. Boil the crushed flowers in the 4 cups of filtered water for 20 minutes.
  3. Cool then strain with the cheese cloth or a kitchen strainer.
  4. Place in your spray bottle and shake to mix.

Using Chrysanthemum flower spray:

Thoroughly spray affected areas and repeat often until infestation is removed. Sunlight breaks down the chemical compound of pyrethrums so re-applying often may be necessary.

Use for:

Almost all insects are affected by this toxin, but be warned that it is equally effective at killing beneficial insects as well.

Special Notes:

  • Can be stored for 2 months.
  • Pyrethrums are also highly toxic to fish and tadpoles so make sure to cover any aquariums.
  • It seems to affect all insects including beneficial ones so use caution if using this product outdoors.
  • It may be irritating to your eyes and sinuses too so spray with caution and away from yourself.
