All of the questions I read about are only for indoor use.
Most people choose to spray insecticide outdoors or to use a bait granule that may fair a bit better under outdoor conditions. The Optigard Ant Bait Gel is labeled for outdoor use:
Outdoor Use
Place bait on, into or adjacent to structures where ants are observed, adjacent to ant trails and to
areas suspected of ant activity. Optimal locations for bait placement are points of entry into the structure
and areas with potential periods of high moisture such as: soffits, eaves, weep holes, and where
pipes and wires enter the structure. Exposure to direct sunlight, extreme heat or cold and water may
reduce length of bait effectiveness. Bait may also be placed outdoors into refillable tamper-resistant
bait stations. Close tamper-resistant stations securely after application. During follow-ups inspect
placements and reapply as needed
