The factors responsible for heavy mortality of Culex tarsalis populations in saran plastic screen cages were investigated. Two compounds, Dow Corning® Antifoam A and Aldo® MLD (glyceryl monolaurate, Glyco Chemicals Ltd.), used as foam preventatives in screen processing, were tested with C. tarsalis. One of the compounds, Aldo® MLD, was shown to be toxic to mosquitoes. Toxic principles were removed easily from saran screening by washing with detergent and water.
