Ants hate chalk, which is a weird discovery some kids inadvertently make on their own during lazy days in the driveway. We don’t need to get into the science of it (which involves a disruption to their pheromone trail); all you have to know is if you don’t want them entering your space, draw a big, fat chalk line and they won’t cross it, as we’ve said. This temporarily confuses them, but it doesn’t kill them, so you’ll need to find a different way to deal with more serious ant issues.
