Three plant extracts, alpha-phellandrene, 1,4-cineole, and patchouli oil were tested for their repellency to American cockroaches and houseflies. Data from differing concentrations of the popular repellent DEET were used as a positive control. The insects were placed in respective choice-test arenas to assess the repellency of these extracts based on the time spent on or near treated filter papers.
