The Pesticide Control Board amended 2 Va. Admin. Code §20-51, exempting certain government employees and other individuals from certification requirements under the Virginia Pesticide Control Act when the intended use of the products is to prevent immediate personal harm from stinging or biting insects. Examples of those exempt include scientists engaging in laboratory research and doctors attempting to control pests in corpses. The rules take effect July 21, 2010. http://legis.state.va.us/codecomm/register/vol26/iss21/v26i21.pdf p. 2557.
