The pheromone (Z)- and/or (E)-14-methyl-8-hexadecenal (Trogodermal) is the main sex attractant for pest carpet beetles, Trogoderma granarium Everts, 1898, Trogoderma inclusum LeConte, 1854, Trogoderma glabrum (Herbst, 1783) and Trogoderma variable Ballion, 1878. This pheromone is often used to detect these pests within granaries, but it has not been reported to have been used to trap beetles in outside environments. We used Trogodermal-baited traps to collect over 3,000 dermestids in 43 dispersed locations in North and Central America; only 85 dermestids were collected in unbaited traps. Nine species of Trogoderma Dejean and individuals of Megatoma Herbst, Orphilus Erichson, Orphinus Motschulsky, and Thaumaglossa Redtenbacher were collected. This study is the first documentation of intergeneric dermestid response to Trogodermal.
