As it warms up in my area, I am already starting to notice fruit flies in the kitchen. I certainly don’t miss having hem around in cooler winter months! They aren’t out in full force yet, but I know it won’t be long.
I understand the temptation for them with all the fermenting experiments on the count, so it isn’t like I a surprised they are around, but it just gets hard when you do to take a drink of something like ginger beer and find a fruit fly floating in the glass AGAIN!
Last summer I tried a few experiments to try to control their numbers. This is the one that I found that worked best.
I took a smaller sized mason jar and put some ginger beer in it (you can use anything sweet and tempting to a fruit fly – even cut up fruit.) Then I covered the jar with a piece of paper and secured it to the jar with a rubber band making sure that it was tight around the jar (no gaps at all). Next, I poked holes in the top with a larger needle. The holes needed to be big enough for the fruit flies to get in, but not get out.
I tried this with plastic wrap at first but if I poked a hole to big that was non productive and I also noticed that after a few fruit flies were trapped in there, that was it, no others seemed to try. That is why I switched to paper, thinking the fruit flies on the outside couldn’t see the ones on the inside and still try to get into the trap. The paper seemed to work really well.
The only downfall I have noticed is, that once you have a ton of fruit flies in there, how do you kill them and get them out without taking the paper off (the lies one fly away!) I managed to shake up the jar enough to get them all wet and then empty it at the sink where I could rinse everything down with water before they had a chance to dry off and fly away. Another option is to set the jar outside and forget about it (yup, I did that) until they all die, then take the paper off and clean out your jar.
I had more than one trap going in the kitchen at a time and switched them out often for a fresh one. I realized that I needed fresh ginger beer in their to keep attracting them into the trap.
Have you made a fruit fly trap that works well for you? Please share you experiences in the comments.
