One question that often puzzles people is why there are ants in bathrooms. We intuitively understand why ants tend to infest kitchens; they’re hungry, poor critters, and are just looking for a snack. But bathrooms?
In truth, though, your typical bathroom is very attractive to ants. One reason is the moisture, which ants love. The smells that emanate from the bathroom also entice their olfactory senses; the various chemicals we store there, as well as the smells from the drains, are appealing to ants.
How to Get Rid of Ants in Bathrooms
So how do you get rid of ants in bathrooms? Cleaning up crumbs or food spills isn’t going to do the job here, obviously.
Can you determine the source of the ant infestation? Sometimes, following a trail of foraging ants will lead you back to their nest, and you can take steps directly against the source of the problem. Alternatively, you can use a liquid ant bait that will allow the ants to carry poison back to their nests, effectively getting rid of ants in bathroom without you having to take the trouble to locate it yourself.
Even if you can’t find the nest itself, you may be able to determine where the ants are entering your bathroom from. Often, this will be a crack in the tiles or groutwork, or where walls or floors don’t meet perfectly. Caulk the area to deny the ants access to your space.
Once you’ve done what you can to secure the perimeter, you want to make your bathroom as unattractive as possible to ants.
The first step is to eliminate the moisture that is attracting the ants. Run a fan or open a window after showering. If you have a rubberized bath mat, hang it up to dry after each use. When leaving the bathroom, wipe down the sink and/or tub or shower to avoid leaving moisture.
Wash down any surfaces where ants have been with vinegar, baking soda, or boiling water. These cleansers disrupt their scent trails, confusing the ants and discouraging them from returning.
As a further deterrent, you can use a natural ant repellent such as citrus peels or cinnamon, or any of a variety of other aromas that ants hate. Especially in a bathroom, which is often enclosed and doesn’t circulate much air, these odors will linger and deter ants, and have the added bonus of working as an air freshener. For the same reason, you may wish to avoid spraying toxic pesticides in a small bathroom, especially if you have children, as you will continue to inhale the unwholesome chemicals for an extended period.
