| 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. |
| If you absolutely have to, you can spray with an insecticidal soap or insecticide that contains pyrethrins. |
| After the extraction of pyrethrins, a total of 9 parts out of 10 parts are left in the powder form, which is known as pyrethrum marc. |
| Pyrethrins act as an axionic excitotoxin on bed bugs, which effectively paralyzes them by messing with the sodium channels that regulate their nerve cells. |
| The synthetic pyrethroids are more stable than the pyrethrins, and are equally or more potent pesticides. |
