1. Deep-Clean Every Drain (This Is the #1 Fix)
    • Pour ½ cup baking soda + 1 cup white vinegar down each drain.
    • Let it foam for 10–15 minutes.
    • Flush with a full kettle of boiling water.
    • Repeat weekly for maintenance. For serious gunk: use a drain brush, a cheap plastic drain snake, or an enzyme cleaner (Bio-Clean, Green Gobbler, Zep, etc.).
  2. Dry the Bathroom Ruthlessly
    • Squeegee shower walls and glass after every use.
    • Hang towels to dry (don’t leave them bunched on the floor).
    • Wipe the sink and counter after brushing teeth or washing up.
    • Run the exhaust fan during shower + 20–30 minutes after. Leave the door open when you’re done.
  3. Lower Humidity Ideal bathroom humidity: 30–50%. If yours is always steamy, get a small dehumidifier or crack a window.
  4. Scrub Hidden Spots
    • Clean grout with an old toothbrush and baking-soda paste.
    • Pull the shower curtain liner all the way open and wash the folds.
    • Vacuum or sweep under the toilet base and behind the tank.
  5. Seal Their Entry Routes
    • Caulk gaps around pipes under the sink.
    • Check that the exhaust fan flap closes properly.
    • Add a fine mesh screen if bugs are coming through vents.
