Researchers at the USDA-Agricultural Research Service find promising results using clay and silicate dusts to combat lone star ticks. They hope the dusts could be a useful tool against tick species that transmit deadly pathogens to livestock.
A study in Tennessee found ticks on about one in six cattle and at livestock monitoring locations in all regions of the state, highlighting a "hidden health threat" to the cattle industry.
Experiments conducted at the U.S. Centers for Disease Control and Prevention showed clothing treated with permethrin had strong toxic effects on three primary germ-carrying tick species, interfering with the ticks' ability to move properly and likely interfering with their ability to bite.
One key factor plays a role in how well any particular tick-management method might work: Which tick species is it best suited for? A new guide in the Journal of Integrated Pest Management reviews research on tick management tools and their effectiveness on three tick species: the blacklegged tick, the lone star tick, and the American dog tick.
