- Cover it with plastic wrap and make some small pores so that flies can get in.
- Flies can get inside jar but will fail to get out. Dispose it and you will get rid of it.
Don’t worry, if you don’t have apple cider vinegar. Regular white vinegar will work fine. However you may be required to add couple of dish soap drops (lemon scented) to the jar to make more attractive to the gnats. Banana Chops or some banana peel in the jar is an excellent alternative.
Possible reasons why homemade vinegar trap is not working for you:
- You are not using enough soap with vinegar. Remember that soap is responsible for sinking the gnats. Vinegar fails to capture gnats and fruit flies. If used alone, insect will touch surface of water and will leave.
- You are not using it in night. Gnats are more attracted towards light bulb and not sun light.
- You are using wine or beer instead of vinegar. Beer are not that attractive when compared to vinegar.
- You are using less stronger vinegar. Apple cider vinegar is very strong, go for it.
