Cockroaches Are Becoming Almost Impossible To Kill Researchers Say After They Are Becoming Immune To Insecticide!
A new study by researchers at Purdue University in West Lafayette, Ind., found evidence that the German cockroach species is becoming harder to kill as the worldwide pest rapidly develops cross-resistance to multiple types of insecticide at one time. The findings were published in the journal Scientific Reports last month.
“This is a previously unrealized challenge in cockroaches,†the study’s lead author, Michael Scharf, said in a statement on June 25. “Cockroaches developing resistance to multiple classes of insecticides at once will make controlling these pests almost impossible with chemicals alone.â€
The researchers tested three methods of professional-grade insecticides on German cockroaches at multi-unit buildings in Indiana and Illinois over a six-month period in 2016. First, they rotated between three different insecticides each month for three months and then repeated. Second, they used a mixture of two insecticides sprayed monthly. Lastly, they used a single treatment — abamectin gel bait — once a month in an area where cockroaches showed a low resistance to abamectin. Posted By PSmooth
