How to Get Rid of Gnats
Learn how to get rid of gnats by identifying fruit flies, drain flies, or fungus gnats, removing sources, using traps, fixing plants, and preventing return.
Quick Answer
To get rid of gnats, identify whether they are fruit flies, drain flies, or fungus gnats, remove the food or moisture source, clean drains and trash, store fruit properly, let houseplant soil dry between watering, use traps, and repeat prevention for at least one life cycle.
Supplies Required
- Trash bags
- Mild cleaner
- Drain brush if needed
- Apple cider vinegar trap or sticky traps
- Sealed food containers
- Houseplant soil check
- Gloves
Safety Precautions

Step-by-Step Instructions
- Step 1
Identify the gnat source
Check fruit bowls, trash, drains, damp soil, recycling, and wet cleaning tools.
- Step 2
Remove food sources
Throw out overripe produce, rinse recycling, and clean sticky spills.
- Step 3
Clean drains and trash areas
Scrub organic buildup and empty trash regularly.
- Step 4
Fix houseplants
Let soil dry more between watering and remove decaying plant matter.
- Step 5
Use the right trap
Use vinegar traps for fruit flies and sticky traps near plants for fungus gnats.
- Step 6
Seal and store food
Keep fruit refrigerated or covered during the cleanup period.
- Step 7

Common Mistakes
- Using traps without removing sources
