By analysing and sequencing the genome of the bed bug, Cimex lectularius, researchers have identified genes associated with insecticide resistance. Over the last 20 years the bed bug has developed abilities which limit the effectiveness of insecticides.

Researchers hope their findings will help uncover mechanisms of insecticide resistance.

The bugs have certain proteins in their cuticle coating that is able to block the insecticide from penetrating the insect. Additionally bed bugs produce an enzyme that can detoxify insecticides.
