Insect & Pest Control
The common nuisance flies in Australia are the house fly (Musca domestica) and the bush fly (Musca vetustissima). Flies are carriers of disease by transmitting disease causing organisms and also cause irritation or fly worry by their presence. Flies are attracted to various types of organic matter including food, decomposing material and faeces. Numbers can build up very quickly with females laying eggs by the hundreds and under suitable environmental conditions of warmth and moisture as well as adequate food sources, the life cycle can be short. In fact, 1 kg of faeces can produce up to 10, 000 flies. Evidence of a fly problem includes regular sighting of flies, presence of the larval stages or maggots in the typical breeding sites and presence of dark spots visible on some types of surface. Fly numbers build up when climatic conditions are conducive typically in spring to autumn or after periods of rain.
Apart from being an annoyance, flies can also spread disease. Flies have been shown to be vectors for diseases such as pinkeye. Furthermore, the irritation flies cause can result in production losses due to reduced weight gain because stock spend more time avoiding flies and less actually feeding. Flies can also spread enteric infections to humans so there is also a public health aspect to fly control.
Control of flies should be based on an integrated approach. This involves limiting access of flies to internal areas by using exclusion methods such as meshes or similar, removing of any potential breeding sites and the use of appropriate chemical control methods. Regular removal of breeding substrates such as faeces, decomposing food or other organic matter and providing good drainage will reduce breeding opportunities. Timing of control programs to start early in the season will help reduce the increase in numbers of flies over that season.
Quickbayt® is an effective chemical fly control product. It is a sugar-based fly bait containing the potent neonicotinoid insecticide, imidacloprid, as well as a sex pheromone which lures flies to the bait. It also includes a bittering agent to avoid possible ingestion by children, domestic or wildlife animals.
Quickbayt® is available in two formulations, a dry, granular bait and a spray. The bait can be sprinkled or placed in shallow containers where flies are seen to congregate. Alternatively the granules can be moistened and spread on hessian material or made into a paste and painted onto surfaces where flies land. The spray is a readily dispersible granule which when mixed with water can be sprayed where needed. It dries almost clear on most surfaces and continues to kill flies for 4 weeks.
Areas which should be treated include: dairy, meat and poultry processing plants, animal housing such as poultry sheds and feedlots and passageways in and outside layer chicken houses and stables. The animals themselves should not be treated with Quickbayt® nor should they have access to baits or spray. Food, water, litter, feed equipment should not be sprayed directly.
