Provided herein are screening methods for identifying compounds for use as an arthropod repellent based on the masking or inhibition of the detection of the skin odor by a cpA neuron. Provided herein are also screening methods for identifying compounds for use as an arthropod attractant based on activation of the cpA neuron. Further provided are one or more compounds identified using the screening methods described herein, and compositions containing such compounds.
