Bed bugs have developed a resistance to the most widely used insecticide

If neonicotinoids no longer work against the elusive and resilient creatures, bed bugs will continue to thrive despite exterminators' efforts

Bed bugs have developed a resistance to neonicotinoids, a group of the most widely used insecticides, according to a new study published in the Journal of Medical Entomology.

Products developed over the past few years to control bed bugs combine neonicotinoids, or neonics, with pyrethroids, another class of insecticide.
