How to Make a Fruit Fly Trap
Well there are many ways to trap fruit flies, so here are a few of the most common traps that you can easily make.
Before you make any trap, you must remove the fruit (or whatever is attracting the flies), like putting it in the fridge. This way the only food left for the fruit flies is the trap you have made.
With any trap you will need bait for the trap. There are many different recipes for fly bait, for the most common is balsamic vinegar, or red cooking wine.
Soap Trap
Get your liquid bait ready in an open jar. Now get ready this involves some chemistry, by putting a few drops of dishwashing liquid detergent you will break the surface tension of the liquid bait and the flies will get stuck. Chemistry is wonderful, isn't it? Put the bait near the fruit fly infested area and wait till they all drown!
Covered Trap
This one involves some quick action on your part. Don't worry, it's fun. Put your fruit fly bait in a jar, but this time cover it up with a plastic wrap almost all the way. Leave an opening about an inch wide so that flies can get in. Then, when you see a whole mess of them in the jar, quickly cover the hole, and voila. Oh what fun.
Bag Trap
Similar to the covered trap above, place a piece of rotted fruit as bait in a plastic zip lock bag. Close the bag up most of the way, but leave it open a bit so that flies can get in. When you have a bunch of flies in there, quickly close the bag. Now you can individually crush them. Kill! Kill! Kill!
Fruit Fly Funnel Trap
With this trap you make a funnel out of a piece of paper. Put your liquid bait at the bottom of the jar. Don't let the bottom of the funnel touch the liquid. Now wait, this may take a while.
Bottle Trap
Similar to the funnel trap, but easier, because you don't even have to make a funnel! Just put some liquid bait into a bottle that has a long neck on it like a wine bottle or two liter soda bottle, for example. The flies will go in and won't easily come out. Then, put the cap back on the bottle when you are satisfied with your catch.
Here's a tip:
If those flies have really annoyed you, after you have trapped them, put the trap in the freezer and make them suffer. Plus you can reuse the trap.
Here is a way of trapping fruit flies so special and perverse that it has it's own page:
Have enough of fruit fly traps yet?
Well, I have.
Honestly, these traps work ok, but there will always be flies that are slick enough to withstand your trapping efforts.
This is why I recommend the vacuum method for getting rid of fruit flies.
