I use Arbico for stuff all the time, outside. Have been thinking about getting some predators for my orchid space, but haven't had time to research yet. My main concern is area is open to the rest of my house via a door I have to leave open for heat/AC, so research would be into not having the little predators come snuggle with me in the bedroom, laundry room, etc.
