Bedbugs, those pesky insects that bite humans at night and hide in beds, travel in luggage and sit behind picture frames are now becoming even harder than before to get rid of.
A new study conducted by researchers from Virginia Tech and New Mexico State University has found that the most common class of insecticide called neonicotinoids, or neonics, which is often combined with pyrethroids in commercial treatments for bedbugs, is no longer so effective at getting rid of bedbugs living in Ohio and Michigan state.
Researchers compared the effectiveness of the common insecticide on bedbugs from homes in the two states with the results of treating bedbugs that had lived in isolation for the past thirty years with the same chemical. The study found that, when targeted, Ohio and Michigan bedbugs were hundreds to tens of thousands of times more resistant to the chemicals than the isolated group of bugs.
This is bad news, as the modern world is running out of effective chemical treatments for getting rid of the pesky bugs, which have been on the rise in recent years.
The researchers in this study concluded that more non-chemical methods need to be used to combat bedbug infestations. Currently, the levels of bedbugs in American is so bad that the pest control company Terminix put together a list of the 15 worst cities in the U.S infested with the insects, as featured on CBS News.
On a positive note, the researchers in this most recent study noted that the most resistant bedbugs in the study only came from two areas. Not all of the U.S. may be facing the same level of resistance. Let’s hope not.
