An arthropod trap with an aerosol dispenser that is remotely controllable to dispense spray doses of an active ingredient such as a pheromone or other semiochemical. Images are captured of trapping media within the trap and are wirelessly communicated to a remote server or application. The dispenser is preferably upside down with the nozzle near the lower extremity of the inverted dispenser. An actuation mechanism controls the spray dose according to a schedule or according to individual sprays commands, each of which may be received wirelessly by the trap. Images of the trapping media may be used as feedback for verifying or modifying the metered dosing schedule.
