Flies cannot chew. Flies have mouth parts that absorb food like a sponge. Their food has to be in a liquid form in order for them to eat it. They have a tongue shaped like a drinking straw to slurp up their meals. Flies that eat nectar or blood do so by using their tongue which is called a proboscis. Even flies that eat other insects do so by sucking out the insides of their victims. When a housefly lands on our food, it vomits on the food. The digestive juices, enzymes, and saliva in the vomit begin to break down and dissolve the food. The fly can then suck up the liquid food with its sponge-like mouth parts. If flies eat food from garbage cans or any other source of contaminated food, some of those germs stick to the fly's mouthparts and when the fly vomits on its next snack (your sandwich?), it transfers some of those germs.
The Bluebottle is a member of a group of flies commonly referred to as 'blowflies' on account of their habit of 'blowing' or depositing their eggs on exposed meat. They are a pest in any buildings where meat is to be found: slaughter houses, canning factories, meat processors and, of course, houses. Outdoors they are associated with decaying animal matter and rubbish tips.
The female fly will enter houses with a loud buzzing noise, searching for flesh for depositing eggs on, or for food and in the process spreading disease organisms
Cluster flies are found in numerous locations, but usually in lofts, roof spaces and around south-facing walls. As the name suggests they are detectable through the sightings of large numbers of adults.
Cluster flies migrate from outdoors into the lofts of houses and farm buildings during the winter months. Obvious signs of an infestation is a roof space containing a large quantity of lethargic flies and a quantity of dead flies. Unless the loft is used for storage purposes or is accessed regularly the flies will hibernate successfully leaving in early spring dependent on the weather.
If the loft is home to a hibernating colony of flies they will return to roof spaces previously occupied so re-infestation is almost inevitable. If the property is annually infested with cluster flies and a significant nuisance is caused, then the answer is to call us in around late August or early September (before the first flies have migrated into the loft) to access the situation and advise on the right treatment. This could include placing cassettes which slowly release fly repellents into the loft space. This creates an unpleasant environment for the scout flies that arrive persuading them to possibly choose another location. However if a major infestation is allowed to occur, the use of insecticide sprays maybe needed.
The most common pest of homes, shops, factories, food establishments and rubbish areas. The adults are attracted to, and breed in, decaying animals, animal waste excrement and vegetable waste.
The result of this is that the House fly is a major health risk and a carrier of a large number of disease organisms, including Salmonella food poisoning and infantile diarrhoea. The House fly is very active during the day and rests at night, looking for edges high up in rooms such as light shades.
The adult flies are 7-8mm in length and greyish in colour, with four narrow black stripes on the thorax. Males have a pair of yellowish patches at the base of the abdomen.
The Lesser house fly is commonly found indoors, especially the males that can be found flying under pendant lamps. As well as being a house pest it is also a major pest of poultry houses and farms where it breeds in manure and other semi-liquid organic matter.
Although many species of flying insect are attracted to ultra-violet light emitted by electric fly killers, the Lesser house fly is not particularly attracted.
Similar to a house fly in size, 8mm long; a grey fly with distinct black spots on the abdomen. A slender, black, piercing mouthpart projects forward from the bottom of the head.
They cause annoyance from painful bites, blood loss; reduced milk production, feeding efficiency, and rate of gain; may transmit equine infectious anaemia (swamp fever), porcine eperythrozoonosis, vesicular stomatitis of cattle and horses, and a mechanical vector of pathogens including anthrax, brucellosis, Salmonella, and others.
Complete metamorphosis completed in 3 to 4 weeks: egg three larval instars (maggots), pupa, and adult. Generational time:
Larvae feed in substrate from the oviposition site, taking nutrients primarily from the microbial flora and fauna therein. Adult habitat, feeding: Off host, stable flies prefer shelter from wind, mostly within 3 feet of ground level; seek host animals and suck blood once or twice daily, preferring legs and feet of most mammals (including humans) and ears of swine and dogs; stable flies usually orient themselves with their tail end toward the ground while on a host; daytime biters. Method of dispersal or infestation: strong fliers, stable flies sometimes 'migrate' many miles; they'll find a host in sunshine or deep shade.
