New Pest Invading North Carolina

Distribution of Asian longhorned tick in North Carolina

We have had requests for information about the Asian longhorned tick (Haemaphysalis longicornis) which is an invasive species that was initially reported as found on sheep in New Jersey in 2017.  However, the USDA-APHIS found a specimen in a sample of ticks that had been collected in West Virginia in 2010 and initiallly misidentified as lonestar ticks.  As of October 1, 2019, the Asian longhorned tick has been reported  in twelve states (AR, CT, DE, KY, MD, NJ, NY, NC, PA, TN, VA, and WV).  In North Carolina, this tick has been found in five counties during the last three years although each case involved one animal or one site.   We now have a publication about the tick’s biology available at:

NCSU Entomology graduate Samantha McPherson is the 2019 recipient of the North Carolina Pest Management Association Graduate Student Scholarship.  The $1500 scholarship is awarded annually by the NCPMA’s Education Foundation.  Samantha is working under the direction of Dr. Jules Silverman and Dr. Coby Schal and studying diet affects the reproductive success of German cockroaches.

Researchers at NCSU have published a study showing that “Total Release Foggers” (or “TRFs”) are ineffective at controlling German cockroaches.  The study published in BMC Public Health  found that the foggers do not reach areas where cockroaches may be hiding and can increase pesticide concentrations in homes by as much as  600X (a median of 85X).  Baiting is far more effective at controlling German cockroaches and reducing potential asthma triggers that result from infestations and the use of certain insecticides.

Post-Hurricane problems.

In the aftermath of severe weather, such as hurricanes, tornadoes and flooding, cleanup efforts are complicated enough without being hampered by a host of pest problems. Visit the Cooperative Extension Disaster Website for helpful information about cleanup and controlling pests.
