Human pores and skin lipids discovered to repel mattress bugs


Unlike different human pests, mattress bugs solely feed on their hosts for a short while earlier than transferring away to cover till it’s time for his or her subsequent meal.

University of Kentucky entomology researchers have discovered that pores and skin triglycerides, or lipids, maintain mattress bugs from staying very lengthy on human hosts. Their discovering may result in new administration methods for this essential human pest.  

“We already knew that human physique odors, carbon dioxide and heat appeal to bed bugs to feed on people. Our latest research shows the reason they do not stay on humans like other pests, such as lice, is due to lipids or triglycerides in our skin that cause them to leave their hosts and hide in nearby locations, such as beds and mattresses,” stated Zach DeVries, assistant professor of city entomology with the UK College of Agriculture, Food and Environment.

DeVries and Sudip Gaire, UK post-doctoral scholar, examined this newest discovering by rubbing a strip of filter paper on contributors’ pores and skin to gather samples. Research contributors represented quite a few ages and ethnicities. They additionally examined the idea on a number of populations of mattress bugs raised within the lab and picked up within the area.  

“Our findings were consistent across all triglyceride types, all participant groups and all bed bug populations,” DeVries stated. “Bed bugs nearly always preferred the control filter strip to the one containing skin triglycerides.” 

“The bed bugs do not like to sit on skin triglycerides and refuse to stay on surfaces that contain triglycerides,” Gaire stated. “We got tremendous results by using only a small amount of triglycerides.” 

While additional analysis is required to discover why mattress bugs don’t just like the triglycerides and if there are different potential mattress bug repellents in human pores and skin, DeVries and Gaire assume this could possibly be an essential starting to simpler mattress bug management.  

“There may be several potential management opportunities from our finding,” DeVries stated. “It’s possible that our findings could be used to deter bed bugs from hitchhiking on people’s belongings, thus reducing their spread.” 

The findings have been first reported in Scientific Reports
