Flies, biology and reasons for fly control
Flies are important for pollination, breakdown of waste and carrion. However flies are also environmental nuisance pests transmitting disease and certain species can bite. Some disease organisms known to be transmitted by flies include Dysentry, Klebsiella sp, Salmonella sp, Escherichia coli and Campylobacter sp. Flies can present serious hygiene problems, and owners of premises might be required to bring infestations under control, in legislative terms, under the clean Neighborhoods and environment act 2005 (section 101) and under food safety legislation when large numbers are presents were food is handled.
Fly species most often encountered are
- Common house flies (musca domestica)
- Lesser house flies (Fannia canicularis)
- Blue and green bottle flies (Calliphora sp. and Lucilia sp. respectively)
- Flesh flies (Sarcophaga carnaria)
- Fruit flies (Drosophila sp.)
- Cluster flies (Pollenia rudis)
- Drain flies (Psychodidae)
- Fungus gnats (Mycetophiloidea)
The most common physical control measures include prevention of breeding and clearance of breeding grounds (waste should be covered, sheeting of manure heaps) and enterance prevented by window and door proofing with fly screens. Electric fly killing units should be strategically placed. Electric fly killers attract flies to the UV spectrum of light and kill with an electrified grid which can be effective for some fly species present within a room. However they they are generally not always effective against (common and lesser) houseflies, especially when large numbers are present associated with favourable breeding sites. However they are ideal in places were flies are attracted to food preparation areas. We have a large number of high quality, professional electric fly killers (EFKs) available for the retail and food industry. In situations were insect bodies need to be retained a replacable glue board is present without an electrified grid that can potentially shatter insect bodies. We can fit these units strategically for maximum efficiency. Other control measures we provide and install include window fly screening and chain screen doors for walk through doorways to prevent fly entry. Call or contact us for a free EFK / fly screening brochure which include prices.
