Ants are ninjas. They can squeeze through gaps you can’t even see. A crack as thin as a credit card is a highway.
Check your windows and doors. Use caulk or petroleum jelly to seal them. Cinnamon sticks in the corner? They hate that too. Weird, right?
Don’t forget the pipes. Ants crawl up water pipes like tiny plumbers. A smear of petroleum jelly around the base stops them cold. It’s like a Slip ‘N Slide of failure.
