FLY CONTROL AND MANAGEMENT
HEALTH: The primary threat from flies is the distribution of disease carrying organisms that affect humans such as salmonella food poisoning, dysentery, typhoid fever, cholera, hepatitis, tuberculosis, poliomyelitis, various parasitic worms and many others. Some flies (fruit flies) are pests of fruit and vegetable production and others are internal parasites of livestock.
PREVENTION: Fly prevention has many factors but personal and public cleanliness and proper waste disposal are main preventative measures. This means cleaning up of food scraps, good garbage management and disposal, minimization of and good management of animal wastes, composting of plant, fruit and vegetable wastes. Inside measures include cleaning up of spills and food wastes and used food containers and other rubbish, also helps. These measures minimise breeding and feeding sites and reduce fly numbers.
Electronic Fly killers have two parts, ultraviolet (UV) tubes to attract insects, an electrified grid to kill them, or a sticky board to catch them. The tubes fitted to electronic fly killers produce UV light. This is not visible to humans but attracts flying insects if it is strong enough. Unfortunately, these tubes do not last forever and lose their effectiveness long before they fail. Because of this, you cannot take for granted that your fly killer is working properly, even if the tubes are visibly lit. In general the tubes need to be changed every 12 months. Once the UV light attracts the insects in, the sticky board catches them, or the high voltage grid or mesh inside the equipment then kills them. The grid can still be live even if the tubes have failed – always turn the unit off at the wall before touching it. Putting the unit in the right place is important to make sure it works properly. Because the effectiveness of UV tubes deteriorates quickly, these must be replaced at least once a year, even if they still appear satisfactory. You should aim to replace them in early spring so that the tubes are at their most effective when flying insect numbers are highest. A reputable pest control company will possess equipment to check the strength of your UV tubes.
