SUMMARY
Hydroprene is an amenity and domestic insecticide without EU regulatory approval for use. It has a low aqueous solubility, is quite volatile and, based on its chemical properties, it is slightly mobile but unlikely to leach to groundwater. It is not generally persistent in soil systems. It has a low mammalian toxicity. It shows a moderate level of toxicity to fish and daphnia but is relatively non-toxic to adult honey bees but may be harmful to bee larvae. GENERAL INFORMATION 
for hydroprene
