Traditionally flies are thought of as a seasonal problem. However now, with the tendency for warmer, wetter weather all year round, frequently they can become a year round issue. Therefore on-going control programmes are essential to keep fly populations at low levels. Whether it is the common house fly, blue bottle, stable or fruit flies good housekeeping and levels of hygiene can go a long way towards helping to keep fly populations down, but sometimes this is just not enough. When further measures are necessary there are a variety of methods that can be used including flytraps, baits, paints, knockdown or residualsprays and biological predators. A crucial factor for any control programme is to BREAK THE LIFE CYCLE and therefore it is necessary to use both larvacides at the breeding sites, as well adulticides. Whichever product(s) you are using read the product labels and use them correctly, ensuring that these are appropriate for the species you are trying to control and the stage, frequently you will need to use a combination of products. Follow the instructions do not take shortcuts, use the correct rates and remember you may need to alternate products during the year, resistance can develop quite rapidly.
