Bed bugs: more resistant than ever to pesticides

5 years ago

A new study published in the Journal of Medical Entomology confirms that bed bugs are more resitant than ever to commonly used pesticides.

In this study, researchers compared the amount of pesticide required to kill bed bugs captured in american households to the amount required to kill bed bugs captured 30 years ago and raised in captivity ever since.

The result:

  • Less than one nanogram was required to kill the bed bugs from thirty years ago;
  • A massive dose of more than 10 000 nanograms was needed to kill the modern bed bugs.

For Dr Izri, entomologist at the Avicenne Hospital in Bobigny, "the fight against bed bugs should mainly be mechanical (vacuuming every day, washing everything with hot water, using dry steam or cold to kill the bed bugs), and using chemicals is not necessarly mandatory" (source).

This is one more reason to prioritize using a steam cleaner when fighting bed bugs.
