3. Place the Trap Strategically
Set the bowl in areas where gnats gather most often, such as:
- Near fruit bowls
- Beside the trash can
- Near sinks
- Around houseplants
- Close to drains
4. Leave It Overnight
Within hours, you’ll likely notice gnats trapped in the liquid.
Continue replacing the mixture every few days until the infestation disappears.
How Quickly Does It Work?
Many people notice a dramatic improvement within 24 to 48 hours.
However, if gnats continue returning, it usually means there’s still a breeding source nearby.
Common hidden sources include:
- Old produce
- Dirty garbage disposals
- Wet sponges
- Drain buildup
- Overwatered plants
Removing the source is just as important as trapping the insects themselves.
