How too kill fruit flies?

One very effective way of trying to reduce the amount of fruit flies in your home is to leave several traps around the most effected areas. You do this by pouring about 3 cm of water in a bowl, cup or container. Add a small amount of balsamic vinegar to attract the flies and add a small drop of washing up liquid. This causes the flies to sink in the water and drown, as opposed to swimming to the side, where they can climb back out and dry off. To finish the trap off, you must stretch cling film over the top, and poke small holes in it with something small like a tooth pick. The flies manage to climb in, but struggle to get back out and as they tire they fall into the water and drown. Leave them around for a day and you'll be amazed at the results. But to really deal with an infestation, you need to attack the problem at source. Place fruit in the fridge, or outside the home. Clean all surfaces immediately after food preparation and don't leave dirty plates, pots etc out. Finding where the eggs are being laid and cleaning that away is necessary also. If you follow all these steps, you should be free from the pests within a week.
