Why Are There Ants in the Bathroom?

​If you’re seeing ants in your bathroom, it usually catches you off guard.

There’s no food sitting out. You’re not cooking in there. And yet, they keep showing up—around the sink, near the tub, or along the baseboards.

In Hampton Roads homes, this is actually pretty common.

At Getem Services, we’ve been helping homeowners deal with issues like this since 1922. After working in homes across the 757 for more than 100 years, our local pest control company has seen how often ant activity starts in bathrooms—and why it tends to stick around.

​Why Ants Show Up in Bathrooms

In bathrooms, it usually starts with moisture.

Sinks, tubs, toilets, and plumbing lines all create small areas of consistent moisture. Even something as simple as condensation under a sink or around a pipe can be enough to attract them. In Hampton Roads, where humidity is already high, those conditions make bathrooms an easy place for ants to settle in or pass through.

Once they’re there, though, it’s not just the moisture that keeps them around. Bathrooms also have small, easy-to-miss residues—like toothpaste in the sink, soap residue, hair products, and organic material around drains. It doesn’t take much for ants to treat that as a food source.

You might notice them along the edge of the sink, around the base of the toilet, near the toilet supply line where it connects to the tank, by the bathtub or shower, or coming out from under baseboards or behind fixtures. In many cases, the moisture draws them in—and those hidden residues give them a reason to stick around.

Where Ants Are Actually Coming From

What you’re seeing in the bathroom is usually just part of a larger issue.

Ants may be coming from inside wall voids near plumbing, underneath the home in a crawl space, or from outside along the foundation and working their way in. Bathrooms often sit right above or next to areas where moisture builds up—especially crawl spaces in this region—which makes them a natural entry point.

So even if the bathroom looks clean, the activity can continue because the source is somewhere nearby, not necessarily in the room itself.

Ants We Commonly See in Bathrooms

Certain types of ants are more likely to show up in bathrooms than others, especially in Hampton Roads homes.

Pharaoh ants are among the most common to watch for. They’re very small and light in color, and they tend to nest inside walls or behind fixtures. That’s why you’ll often see them around sinks or near plumbing areas.

Odorous house ants also show up frequently. While they’re known for being in kitchens, they’re just as likely to appear in bathrooms if there’s moisture present. They’re tiny and easy to miss at first.

Carpenter ants are less about food and more about moisture. If there’s damp wood around a window, baseboard, or wall, they may be drawn to that area. Seeing them in a bathroom can sometimes point to a moisture issue nearby.

Why Ants Keep Coming Back

This is where most homeowners get frustrated.

You wipe them up. You clean the area. And a few days later, they’re back in the same spot.

That happens because the source hasn’t been addressed.

Ants leave behind scent trails, especially in areas where they’ve found moisture. Once that path is established—like along the edge of a sink or behind a toilet—they’ll keep using it. And if the colony is nearby, new ants will keep appearing.

That’s also why quick fixes don’t usually solve the problem. Sprays might get rid of the ants you see, but they don’t reach inside walls, behind cabinets, under flooring, or near plumbing access points.

In some cases, over-the-counter products can even push ants deeper into the structure or into new areas of the home. That’s when the problem shows up again—sometimes in a different bathroom, or somewhere else entirely. It’s something we see a lot when it comes to ant control in Hampton Roads homes.

What It Takes to Get Rid of Ants

Getting rid of ants in the bathroom means looking beyond the surface. At Getem Services, we focus on where ants are coming from and what’s allowing them to thrive.

When we’re called out for ants in a bathroom, we’re looking at how they’re getting in around plumbing and fixtures, whether conditions are contributing to the problem, where the colony is likely located—inside or outside—and how the ants are moving between areas of the home.

From there, we treat the problem at the source, not just where the ants are visible.

Ongoing Protection Matters in Hampton Roads Homes

Ant activity in bathrooms isn’t usually a one-time issue.

With the humidity in Hampton Roads and the way homes are built—especially those with crawl spaces—conditions tend to remain favorable for ants year-round.

That’s why ant control is included in Getem’s residential pest control plan.

With quarterly exterior pest treatments, we’re able to stay ahead of ants and other house-infesting pests rather than react after they appear. If indoor treatment is necessary, we handle it, too.

It’s not just about getting rid of ants once—it’s about keeping them from becoming an ongoing problem.

​Ant FAQs for Hampton Roads Homeowners

Are ants a sign of a leak or moisture problem?

Sometimes, yes. Ants often seek out damp areas, so their presence can point to excess moisture—whether it’s condensation, humidity, or a small leak that hasn’t been noticed yet. It’s not always the case, but it’s something worth paying attention to.

Why do ants show up around my sink or toilet specifically?

Sinks and toilets create consistent moisture and small gaps where plumbing enters the wall or floor. Those areas make it easier for ants to find water and access hidden spaces inside the structure, which is why activity often shows up there first.

Is it normal to see ants even if my bathroom is clean?

Yes. Bathrooms can attract ants even when they’re clean because they provide consistent moisture and access points around plumbing. That’s why the issue can feel confusing compared to ants in kitchens, where food is usually the main factor.
