How to repel insects with beer
Kill fruit flies with an open beer can.
Fruit flies (also called vinegar flies) are attracted to fermented beverages like beer and wine. For an effective fruit fly trap, leave an open beer can sitting out with a small piece of paper taped over the lid.

Pick from:
-You should also put a length of aluminum foil over the top of the can to catch the flies. The foil should cover the can tightly, which means the flies won't be able to get out.
-This will draw insects to the open beer can and allow them to find the beer. Studies have demonstrated that drinking an unopened beer can 23 times in a one month period can attract wasps to the beer.
-Poke a small hole in the paper to allow the flies to enter the can. They will be unable to find their way out and will eventually drown in the beer.
-Pour vinegar into the can to attract flies, then spin it around with a long piece of string. All you need to do is drop it over the trap and leave it there.
Poke a small hole in the paper to allow the flies to enter the can. They will be unable to find their way out and will eventually drown in the beer.
