Editing Pyrethrum (section)

=== Other animals ===
Pyrethrum, specifically the pyrethrin within, is highly toxic to insects including useful pollinators like bees. The risk of killing bees and other beneficial insects is partially reduced by the compound's rapid breakdown (a half-life of approximately 12 hours on plants and on the surface of the soil, with about 3% remaining after five days, but persisting several weeks or more if it enters a body of water or is dug into the soil) and its slight insect-repellant activity.<ref name=NPIC>{{cite web |title=Pyrethrins general fact sheet |url=http://npic.orst.edu/factsheets/pyrethrins.pdf |website=national pesticide information center}}</ref>
