Riviera Pest and Falconry covers all aspects of pest control in both domestic and commercial properties in Devon.
Flies are our most common insect and pose a serious threat to humans, pets and livestock. They spread diseases, contaminate food and some can bite. Flies can be a nuisance when buzzing around your home or business but if you see flies in large numbers you could be facing an infestation which will require professional assistance.
There a number of common species that we usually have to deal with:
Houseflies complete their life cycle of egg, maggot, pupa, adult, in a week during warm weather. The eggs are laid in batches of about 120 on any rotting organic matter and the legless white maggots burrow into this food until ready to pupate in loose soil or rubbish.
Blue Bottle Fly: One of our larger species of flies and a large quantity in an area usually indicates a dead carcass or rotting food matter nearby. The Bluebottle is a large buzzing fly with shiny, metallic blue body, 6-
12mm long. One Bluebottle can lay up to 600 eggs, which in warm weather will hatch in under 48 hours and produce maggots which can become fully developed in a week. These maggots burrow into meat or carrion as they feed on it, and then pupate, often in loose soil, for about ten days before emerging as adult flies from the brown pupal case.
During the summer months Cluster Flies live out in the fields where the larvae feed on earthworms until it is ready to pupate. As autumn approaches vast numbers of them start seeking out places to over winter and will often use lofts, out houses and sheds. Once the weather warms up they become active again they leave and start the process over again. The common Cluster Fly is large and black and they are very similar to house flies so can easily be mistaken for them. The difference is their yellowish golden hairs on the thorax and a prominent dark and light coloured chequered pattern on their abdomen. At rest, both wings overlap across the abdomen and they tend to be sluggish in flight. There are a few other cluster fly species that vary slightly in size and colour, but the common cluster fly is the one you’ll be mostly likely to find in your loft space.
This is a small species of fly (2-3mm) and can be recognised by its red eyes. They are commonly found around the home, restaurants and pubs where food has been allowed to ferment or liquid spillages that haven’t been cleared up. Although considered more of a nuisance they can cross contaminate foodstuffs. Once they begin reproducing indoors, females are able to lay about 500
eggs and the eggs will hatch in as little as a few days after being deposited by the female. This makes the pests difficult to control.
Another small fly that grows to around 2-4 mm in length and are light grey or tan in colour with lighter-coloured wings. The body and the wings are covered with long hairs, giving the fly a fuzzy appearance. If these flies are present in the house there is almost certainly a slow or clogged drain. Drain flies gather, mate, and lay eggs in moisture or standing water. The slimy film that forms in sewers and drains is a favourite breeding spot.
tREATMENT: Putting off regular cleaning and maintenance of these areas may attract the pests and offer them a place to feed and develop. These pests are a nuisance because they infest in large numbers. Once inside, drain flies may plug pipes and spread bacteria from the filth they live in, possibly contaminating food in the process. These pests, even though they live in filth, are not known to spread any disease to humans.
