Insects are able to climb almost any type of surface using their specialised adhesive organs. So far, most technical solutions to control insect pests involve toxic or sticky components, which need to be frequently renewed. Scientist at the Biomimetics-Innovation-Centre Bremen and Kiel University have now developed and tested a new bio-inspired repellent technology without toxic or sticky components.

"There are a few natural surfaces that make it difficult for insects to climb and walk across," said Dr. Elena Gorb (Kiel University). "One thing these slippery surfaces have in common is that they use combinations of different roughness. The nanostructured surfaces are not smooth enough for the adhesive pads, and not rough enough for the claws to interlock. This makes it difficult for many insects to climb."
