Fly Information

The fly has been documented as a symbol of death and decay across cultures throughout history. From the biblical fourth plague of Egypt to modern television adverts that depict children of third world countries that are blighted by the insect. The fly has the capability to spread extremely quickly; the insect is well suited to multiplying fast. A female fly lays up to 200 eggs in each laying period and from egg to fly takes approximately 8 days.

Musca domestica: The House Fly
Typical values for the life stages at 33°C:
Egg: 13 minutes
Larvae: 4  days
Pupa: 2 days 15 hours
Pre-oviposition: 1 day 8.5 hours 

The female fly attracts the male with the sex pheromone Muscalure (Z-9 Tricosene). The effectiveness of this sex pheromone provides another example of how the fly is able to multiply and become so problematic in such a short space of time. The male fly’s brain is wired to do only two things- eat and multiply. It will aim to act upon these insects continually until it dies with a life expectancy of up to 30 days. This attractant has been specially formulated in Sheila and Twenty one to lure the fly to its death. Fly control is vital.

It is essential that farmers keep the ever present problem of flies under control. The clean neighbourhoods and Environment Act 2005 states that ` any insects emanating from relevant industrial trade or business premises and being prejudicial to health or a nuisance` must be taken care of. Therefore if flies are proven to be stemming from a farm, the farmer must control the flies. If found guilty the farmer can be fined up to £20,000 or face a custodial sentence for up to 6 months.

In addition to being required by law to rid a premises of flies there are countless other reasons to do so. The fly harbours and can transmit in excess of 100 diseases including salmonella. This is particularly problematic for the farm as it is a perfect habitat for the fly. Deep pit free range poultry houses, indoor pig units, dairy units, calf pens and slurry pens provide conditions which enables the fly to thrive.

Flies are particularly attracted to eyes, teats and open wounds of animals as well as animal feed. They cause fly specks on eggs and it has been proven that flies cause a marked reduction in egg production. It is confirmed that flies will lead to a reduction in milk yield and meat production and also cause animals to become distracted from grazing. Fly problems can be costly.

It is easy to see why flies transmit disease so quickly. As well as fly to surface contact, the fly can ingest food material just by sucking up liquid foods. Alternatively, it uses sharp bristles (“teeth”) on the pseudotracheae to scrape the food surface, and then moistens it with regurgitated saliva and liquid vomit, so that a liquefied material can be ingested.

It is essential to control fly problems, Lodi UK’s products provide farmers with a fast and effective solution. Infestations need to be addressed as they will only get worse.

Did you know?

Flies have a smelling distance of over 750 yards.
A fly's feeding range is usually limited to two miles.
A single garbage can, if not emptied, can be the breeding ground for 30,000 flies.
During warm weather, a fly can produce a family generation in less than two weeks.
Flies are also dormant in the winter which means that the same diseases can be carried over one year to another
