SUMMARY

Emperithrin is a pyrethroid, broad-spectrum insecticide used in domestic and utility situations. It is not approved for use in the EU. It has a low aqueous solubility and is highly volatile. Environmental fate data is scarce. Emperithrin has a low mammalian toxicity. It is not highly toxic to birds but is a greater risk to aquatic organisms.
