DIY Gnat Traps

A vinegar trap for gnats.I have had a problem with gnats in the house and have used vinegar to trap them. Yesterday, I decided to put a bowl of vinegar outside to see how many I could catch. In just a few minutes, they were gathering on the edge of the bowl and drowning in the vinegar. I caught some house flies and yellow jackets as well.


Today, I made another trap using the empty vinegar bottle. About 1/3 up from the bottom, I cut an upside down V shape hole on the side and pressed it inward. It was too big and the gnats were going in and out. So, I took a hook and pulled the flap back up and put a piece of tape across the bottom of the cut to make the hole smaller. It worked well and the gnats go in and can't come out. The hole is too small for bees or yellow jackets to enter. All the gnats need is a crack to enter the bottle.

Maybe if I can catch gnats outside, I won't have as many in the house. I haven't seen any more in the house since I put the traps outside. If I have a problem with them again, I'll just set out some more vinegar traps. They love that smell.
