(CNN) – Not letting the bed bugs bite just got a lot harder. A new study reveals bed bugs have developed a thicker skin. This extra layer protects them against commonly used bug sprays.
The University of Sydney study was funded in part by a company that creates bed bug killers. According to their researchers, the bloodsucking parasites have made a come back in recent years, partly because trying to kill them has only made them stronger.
To keep the critters from spreading, the environmental protection agency recommends removing items from the infested room in sealed plastic bags. Treat the items with a pesticide or in extreme temperatures.
A clothes dryer on high heat works, or you can put the items in a freezer for 4 days. Also, empty the vacuum after each use.
If you have to throw out furniture, make sure you do so responsibly. Destroy it so someone else won’t be tempted to bring it into his or her home.
Finally take steps to have infested items picked up as soon as possible by your trash collectors.
