Pyrethrum in Chrysanthemum

Pyrethrum is the natural chemical derived from the plant. The substance pyrethrin found in pyrethrum makes it a potent pesticide and repellent.

This chemical is natural and non-toxic. However, commercially produced insecticides incorporate other potentially harmful compounds.

For example, piperonyl butoxide is added to pyrethrum-based products. A mix like this can be dangerous in large amounts. So, you must use these with caution.

The best and safest way to use chrysanthemums as an insect repellent is to make your own. This will certainly be an all-natural solution. Nevertheless, you must use the product carefully because it can still cause skin irritation and harm to your pets and fishes.

How to Use Chrysanthemum as a Repellent

When doing the following steps below, make sure not to expose your skin too much on the extracted liquid. Most importantly, use personal protective equipment and do not handle them with your bare hands. The minimum protection you can use is gloves. If you are going to be exposed with the plant’s vapours, use a mask as well.

This high concentration of oil or powder can be harmful when not properly handled.

Also, never throw away large amounts in bodies of water as this can harm fishes. Pyrethrin easily degrades upon exposure to high temperatures and sunlight. It is better to expose it first before disposing of it.

Use the products sparingly unless you are just planting the flower itself because the plant is considered safe unless consumed.

1. Use Chrysanthemum as a Companion Plant

This is the most natural method if you want to use this plant as a natural insect and pest repellent. The scent that the flowers give off is repulsive to common garden pests and simply planting them near the other plants you want to protect can consequently help.

Grow your own by buying Chrysanthemum seeds available on Amazon. Many variants of chrysanthemums are available on the market. However, not all of them contain pyrethrum. Make sure to buy the correct variants: Chrysanthemum cinerariifolium and Chrysanthemum coccineum. Planting the wrong Chrysanthemum plant that does not have pyrethrum will not have the same repelling effect.

First, boil 1 liter of water. Then, harvest flowers in full bloom. Like in number 2, choose those growing near the plant center. The pyrethrum in these flowers is more concentrated.

Next, take the water off the heat and let cool in a pot until its temperature ranges from 160-170 degrees Fahrenheit (70-80 degrees Celsius). Put at least 50 grams of the flowers in the water and submerge them. Remember not to inhale the vapors coming from the hot water. You can use more flowers for a more concentrated solution.

Last, leave the flowers soaking for 1-2 hours. Cover the pot during this time. Once completely cooled down, drain the solution to get rid of the flowers. Transfer the liquid into a spray bottle and use it as an all-natural pesticide.
