How To Make Fruit Fly Traps
4. Paper Cone in a Jar
If you are feeling creative and/or you want to create a trap that is likely to be more effective, using a combination of a jar and a paper cone could be your best option. It is a little more challenging than some of the other options but is still not particularly difficult to make. Take a jar, and remove the lid if it has one.

You should then take a piece of suitably sized paper and fold it so that it makes a cone shape. Tape the cone into position, making sure that it fits correctly, and cut the bottom part of the cone to make an entrance. This method will make it easier for the flies to get in but also harder for them to get out.
