Botanical Name: Chrysanthemum
Chrysanthemums are not only admired for their vibrant colors but also for their natural insecticidal properties. These flowers contain a powerful pesticide called pyrethrum, which is effective against various pests such as roaches, ants, beetles, and ticks.
Pyrethrum disrupts the nervous system of insects, making them immobile and eventually leading to their demise. Here’s a homemade trick to make a pyrethrum-based insecticide. You’ll need:
- Dried Chrysanthemum flowers (preferably white varieties)
- Pestle and mortar or coffee grinder
- Spray bottle
Collect or purchase dried Chrysanthemum flowers. White varieties tend to have higher pyrethrum content. Grind the dried flowers into a fine powder using a pestle and mortar or a coffee grinder. This will help extract the active pyrethrin compounds.
In a container, mix 1 tablespoon of the powdered Chrysanthemum flowers with 1 cup of water. Stir the mixture thoroughly and let it sit for a few hours to allow the pyrethrins to infuse into the water.
Strain the mixture to remove any solid particles using a fine sieve or cheesecloth. Transfer the liquid into a spray bottle for easy application.
Before using the homemade pyrethrum spray, conduct a small patch test on a few leaves of the plant to ensure it does not cause any adverse effects.
Spray the pyrethrum solution directly on the affected plant areas, focusing on the pests and their hiding spots. Thoroughly coat the pests and their eggs, as pyrethrum works upon contact. Repeat the application as needed, especially after rainfall or heavy irrigation, as the effects of the spray may wash away.
