- Essential oils: peppermint, tea tree, eucalyptus (a few drops in a spray bottle with water)
- Sticky yellow traps or wine-vinegar traps near drains to catch adults
- Cucumber slices or bay leaves (old-school trick that sometimes works)
What NOT to Do
- Don’t just fog the room with bug spray — it doesn’t touch the larvae in the drain.
- Don’t pour straight bleach down drains regularly — it damages pipes and doesn’t kill eggs well.
- Never mix bleach + vinegar (creates toxic chlorine gas).
When to Call a Pro
If you’ve done everything above for 2–3 weeks and they’re still everywhere, or if you notice black mold behind walls or bugs spreading to the kitchen, call a pest-control company. (Thankfully, this is rare — consistent cleaning solves almost every case.)
The Bottom Line
Those tiny black bugs aren’t a sign you’re failing at housekeeping. They’re just nature’s way of telling you there’s moisture and food somewhere it shouldn’t be.
Fix the moisture → remove the food source → they disappear and stay gone.
