For the last 6 to 9 months I’ve been using (selectively, periodically) the Optigard ANT product to beat down the ant population when they become overbearing in the kitchen.
I don’t find a few ants here and there … but when the SWARM the kitchen, usually after a few days of heavy rain, I’ll lay down a line of Optigard ANT gel and thin the ant herd back to acceptable levels.
