The timed pyrethrin sprays. It's possible to buy cannisters in bulk (eg. pestrol brand in australia, or some other brand), and place the cannisters (with their battery operated mist ejector tops) in strategic spots, and have them fire puffs of pyrethrin mist into the air every say 1 hour or so.

Those are never intended for use outdoors or in any unenclosed space.
