Bed bugs develop resistance to widely used insecticides - BBC News
Quote:
A new study indicates that bed bugs in the US have developed resistance to neonicotinoids, the most widely used insecticide in the world.
Researchers found the blood sucking insects in Cincinnati and Michigan had "dramatic levels" of immunity to regular doses of the chemicals.
To kill these bugs required concentrations 1,000 larger than needed to eliminate non-resistant creatures.
The scientists say non-chemical methods of control now need to be considered.
