An economic perspective on outdoor residential pesticide use

Article Abstract:

Outdoor residential pesticide use has remained steady at about half of all US households during the past 20 years. However, the proportion of households that have turned to professional treatments has been increasing. This trend reflects the increased benefits of using professional pest control or the increased costs of using residential pesticides without professional assistance. In view of the potential adverse effects of outdoor residential pesticides on the environment and public health, public policy makers are advised to review the behavioral and economic profile of household pesticide usage.
