Abstract

The purpose of this study was to investigate a safer pest control method for both urban and agricultural applications. In this method, carbon dioxide gas and air were applied within a non-toxic aqueous foam. The CO2 foam was designed to spread over crops or substrate and to persist until insects suffocate in the anoxic foam after a sufficient length of exposure. The surfactants that were mixed with water to create the foam are harmless to the environment, as well aS inexpensive. The foam would be removed by a spray of water or would simply disintegrate. Laboratory toxicity studies on common urban and agricultural pests were conducted. For German cockroaches in particular, mortality for CO2 foam was significantly higher than mortality for air foam. The results indicated that CO2 foam could effectively control some urban and agricultural pests without the coincident use of pesticides.
