SUMMARY
Butanethiol is an odourous animal repellent used to protect ornamental areas. It is highly soluble in water and is also highly volatile. Whilst little ecotoxicity data is available butanethiol is not thought to be highly toxic to biodiversity especially considering its potential pattern of use. It is moderately toxic to humans if ingested and is a recognised irritant.
