This spray uses the synthetic pyrethroid actives 1R‑trans phenothrin (0.125%) and prallethrin (0.10%) in a flammable aerosol base, providing fast knockdown when sprayed into the air or directly at insects. Directions recommend closing doors and windows, spraying in a sweeping motion for 8–10 seconds per average room, then keeping the room closed for about 15 minutes before ventilating thoroughly, avoiding contact with people, pets, food, and aquariums.
