The present invention discloses systems and methods for controlling arthropod populations. The systems include a polymeric substrate, a semiochemical that is reactive upon an adult-stage arthropod, and an insecticide that is toxic to an immature- stage arthropod. The semiochemical may be a sex pheromone that disrupts mating behavior of the adult-stage arthropod. The insecticide may be a per os insecticide that only affects the immature-stage arthropod. The arthropod to be controlled may be gypsy moths, in which case the semiochemical may be disparlure and the insecticide may be spinosad. Further disclosed are methods for preparing systems for use in controlling arthropod populations.
