Hey folks,
Lately, I’ve noticed a surprising amount of ant activity in my bathroom — crawling around the sink, the tub, even the windowsill. I always assumed ants were only after food, so it’s kind of baffling to see them hanging out where there’s none.
After doing some digging, I learned they’re actually drawn to moisture and warmth, which makes bathrooms a perfect hangout spot. I’ve already wiped down surfaces, sealed the obvious cracks, and even used a bit of vinegar spray, but they keep finding their way back.
Ants love bathrooms because of the steady water source — especially leaky faucets or damp tile grout. I had the same problem and didn’t realize a small drip under my sink was keeping them around. Fixed the leak, problem solved.
Good call on checking moisture. I also found they were sneaking in through the tiniest gap near the shower pipe. Used silicone caulk to seal it tight, and haven’t seen a single ant since.
For anyone avoiding harsh chemicals, try peppermint oil or lemon eucalyptus. Works surprisingly well! I spray it once a week around the floor edges and baseboards, smells great too.
Caulk is your best friend here. Don’t waste time with sprays, seal the entry points, especially around plumbing. I also added weather stripping under the bathroom door just in case.
Funny thing, ants can actually come up through drain lines when it’s dry. I pour boiling water down the drain every few days and that seems to break their trail. Simple but effective.
Totally agree about sealing cracks, but don’t forget the vents! I found a small opening near the bathroom fan that led straight outside. Ants were literally marching in from there.
If they keep returning, try a bait gel like Advion. The workers bring it back to the colony and wipe them out completely. Just keep it away from pets and kids.
I swear by diatomaceous earth. Sprinkle a fine layer behind the toilet or vanity — it’s safe and kills ants naturally by drying them out. Took about a week, but totally worth it.
Humidity is a big factor too. Running the exhaust fan more often or using a mini dehumidifier helps a ton. Dry bathroom = fewer pests overall.
Ants are just following water trails. The long-term fix is sealing entry points, keeping it dry, and killing the colony, not just the scouts. Think of it as pest-proofing, not just pest-killing.
