Bean leaves can trap bedbugs, researchers find
Date:4/10/2013

tanically as trichomes.

Using the bean leaves as templates, the researchers have microfabricated materials that closely resemble them geometrically. The synthetic surfaces snag the bedbugs temporarily but do not yet stop them as effectively as real leaves, Loudon said, suggesting that crucial mechanics of the trichomes still need to be determined.

Theoretically, bean leaves could be used for pest control, but they dry out and don't last very long. They also can't easily be applied to locations other than a floor. Synthetic materials could provide a nontoxic alternative.

"Plants exhibit extraordinary abilities to entrap insects," said Loudon, lead author of the paper. "Modern scientific techniques let us fabricate materials at a microscopic level, with the potential to 'not let the bedbugs bite' without pesticides."

"Nature is a hard act to follow, but the benefits could be enormous," Potter said. "Imagine if every bed bug inadvertently brought into a dwelling was captured before it had a chance to bite and multiply."
