We screened the contact activity of 32 commercial essential oils (EOs) and their synergistic effect with β-cypermethrin against Blattella germanica . Results showed that the most effective EOs against B. germanica were from Illicium verum , Syzygium aromaticum , and Cinnamomum camphora , with LD 50 values of less than 500 μg/insect. The most potent synergistic effects of β-cypermethrin on B. germanica were from Dysphania ambrosioides and Mentha canadensis . Both oils have a co-toxic factor of 133.33. The results of the major compound testing of the EOs showed that trans -anisaldehyde and thymol have the best insecticidal activity against B. germanica , with LD 50 values of 141.30 and 138.61 μg/insect, respectively. The compounds with the best synergistic effect on β-cypermethrin were γ-terpinene and linalool at a concentration of 0.5%. The co-toxic factors for γ-terpinene and linalool were 150 and 133.33, respectively, which were similar to the synergistic effect observed with 2% piperonyl butoxide.
