Chlorpyrifos was used to control insect infestations of homes and commercial buildings. These uses were banned in the United States in 2000 and in Europe, later in decade. South Africa banned this application in 2010. Singapore restricted its use as a termite control in 2009.
In 2010, India barred Dow from commercial activity for 5 years after India’s Central Bureau of Investigation found Dow guilty of bribing Indian officials in 2007 to allow the sale of chlorpyrifos.
Chlorpyrifos has not been permitted for agricultural use in Sweden at all (usage as a pest controllant is an exception - the last approval ran out in August 2008). A number of restrictions have occurred in a number of countries, most notably Hawaii which in June 2018 signed a bill banning chlorpyrifos in manufacturing, distribution and use. Hawaii was the first US state to enact such bans. California followed Hawaii’s decision in May 2019.
