Flightless bed bugs in the US have become resistant to the most widely used class of chemicals

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.

Thanks to the increase in the global human population and the rapid expansion of international travel, the flat bodied bed bug has become a source of considerable irritation in hotel rooms all over the world.
