A Review of the Evolution of Termite Control: A Continuum of Alternatives to Termiticides in the United States with Emphasis on Efficacy Testing Requirements for Product Registration

SIMPLE SUMMARY: Termites are structurally destructive pests that can infest a consumer’s most important investment, their home. The evolution of termite control is complex, involving people’s understanding of termite biology and behavior, building construction, the use of soil termiticides, baits, wood treatments, and physical barriers, as well as regulations from different industries (pest control and building construction). Soil termiticides have been the standard method of treatment for decades, but the concern for human and environmental health has driven the development of alternatives. This article discusses the evolution of termite control methods that were alternatives to the standard of the time and the regulatory structure that provides a level of consumer protection for some products. ABSTRACT: The global economic impact of termites is estimated to be approximately USD 40 billion annually, and subterranean termites are responsible for about 80% of the total impact. Twenty-eight species of termites have been described as invasive, and these termites are spreading, partially due to global trade, making effective control methods essential. Termite control is complex, as is the biology and behavior of this social insect group. In the U.S., termite prevention and control (with claims of structural protection) is regulated by more than one industry (pest control and building construction), and at the federal and state levels. Termite prevention has historically relied on building construction practices that do not create conducive conditions for termite infestations, but as soil termiticides developed, heavy reliance on pesticides became the standard for termite control. The concern for human and environmental health has driven the development of termite control alternatives and regulation for products claiming structural protection. Product development has also provided unprecedented opportunities to study the biology and behavior of cryptobiotic termites. Technological advances have allowed for the re-examination of questions about termite behavior. Advances in communications via social media provide unrestricted access to information, creating a conundrum for consumers and science educators alike.
