I use Hot Shot Foggers/6 on my porches, garages basement, storage sheds and roof on the dock, the product lasts for the entire season as long as 12 months for me. No gloves, glasses or any protection necessary. It's cheap and it's available at Home Depot, Lowes and Wal Mart. Look for the green box. I suggest using generously and buy plenty. If I see any signs of ants or any bugs I just hit 'em again... Use of the product has completely changed outdoor living for me.
