Once ants have entered your bathroom, they are naturally drawn to damp areas like the toilet. Household staples like borax and vinegar can safely repel the pests.
To use vinegar to get rid of ants in a toilet, identify the areas where ants are most active. Then, mix equal parts of white vinegar and water in a spray bottle.
The scent of vinegar is a natural deterrent, disrupting the ants' pheromone trails. Spray the solution on the ant-infested areas and entry points, and wipe down the toilet with it.
Another method is to dissolve one part borax with three parts sugar or maple syrup in a bowl of warm water. Place this mixture into small containers and place them at entrances.
The ants will be lured to the bait and carry it back to their nest, and the borax will disrupt the ants' digestive systems and eliminate the entire colony.
It's essential to maintain consistency with both methods. Keep applying the vinegar spray regularly, and give the ants enough time to carry the borax back to their nest.
