What bugs do Pyrethrum Chrysanthemum repel?

Pyrethrum chrysanthemums are effective at repelling a variety of insects, including mosquitoes, flies, fleas, and ticks. The natural chemicals (pyrethrins) found in the flowers disrupt the nervous systems of these pests, making them a popular choice for organic pest control. Additionally, they can deter other common garden pests like aphids and whiteflies. However, while they repel many insects, they can also be harmful to beneficial insects if used indiscriminately.
