| The synthetic pyrethroids are more stable than the pyrethrins, and are equally or more potent pesticides. |
| These synthetic chemicals mimic the action of natural pyrethrins derived from chrysanthemum flowers. |
| Many of these sprays contain one or more of a group of insecticidal compounds known as pyrethrins. |
| Traditional pharmaceutical treatments include two main pesticides, lindane and pyrethrins. |
| If you absolutely have to, you can spray with an insecticidal soap or insecticide that contains pyrethrins. |
| Citrus-oil products, pyrethrin products, as well as those with pyrethrins and diatomaceous earth, may be effective. |
