Stinger96 Posted February 21, 2019 Share Posted February 21, 2019 Anybody have experience in this process? Make Your Own Pyrethrin Insecticide Spray You can make your own pyrethrin insecticide from homegrown pyrethrum daisies. Once the plant is blooming, pick off the full blooms and dry the flower heads in a cool, dark, and dry place. Store the dried flower heads in a tightly sealed, airtight container. When you are ready to use them, grind up 1 cup of flower heads to a powder, mix the powder with a little liquid soap to increase the spreadability, and combine with enough water to make a sprayable solution. Pour the solution into a spray bottle, and use it as you would storebought insecticide. Be sure to label the bottle and store it out of reach from any children. The strength of homegrown pyrethrin varies based on the flower heads, so feel free to experiment with the proportions until you achieve effective control. Anybody have experience in this process?
