University of California researchers identify effective termite control chemical

Researchers at the University of California, Riverside have identified a highly effective method for controlling drywood termites using a chemical called bistrifluron. According to a study published in the Journal of Economic Entomology, this insect growth regulator targets the molting process by interfering with exoskeleton formation.

In laboratory experiments, the chemical achieved a 95.7 percent mortality rate when termites were given a choice between treated and untreated wood, rising to approximately 99 percent mortality with continuous exposure. Nicholas Poulos, a doctoral student at UCR, noted that the chemical is more environmentally friendly than traditional treatments because it is specific to insects and does not harm humans.

Effective termite management typically involves choosing between bait stations and liquid treatments. Bait stations utilize slow-acting insecticides to eliminate entire colonies by spreading the substance through grooming and feeding behaviors. In contrast, liquid treatments provide immediate protection by creating a chemical barrier around a structure.
