Information On Flies
Adult Houseflies (Musca domestica) are 5-8 mm in length with a grey thorax and 4 narrow longitude stripes. They have a buff or yellow abdomen and are covered with small hairs. Their larvae are up to 12mm in length, white in colour and taper to a point at the head end. They have 2 spiracle “spots” at the hind end. Each female housefly can lay up to 500 eggs in several batches of about 75 to 150 eggs, over a 3-4 day period in almost any warm, moist material that will supply suitable food for the larvae. In warm weather their eggs hatch in 12-24 hours.
Fly infestations & Risks
Flies are major carriers of disease and are known to transfer over 100 pathogens resulting in ailments, including typhoid, tuberculosis, cholera and dysentery. They collect these pathogens on their legs and mouths when feeding on feces, garbage and other decaying materials. Common houseflies flit about from place to place with a flight range of at least 8km (5 miles) and are highly active indoors.
Fly Pest Control
The best method of fly control is to physically break the breeding cycle, by making sure they cannot find anywhere to breed. Fly screens and Electronic Fly Killers (EFK’s) are often used in commercial premises to control flying insects including the Housefly.
Good hygiene is essential in all fly management, and the proper disposal of waste food and other materials on which the flies can lay eggs is a priority. Food should be covered or kept in suitable containers. Remove all “empties”, bottles or cans, and check for rotting fruit, meat, vegetables or pools of spilled liquid. Waste food and other household waste should be placed in plastic bags, sealed, and properly disposed of in dustbins which have proper fitting lids. Ensure all bins are emptied and cleaned regularly and are sited away from the entrances to buildings.
In order to obtain the best results, insecticidal control measures using products labelled for flying insects should be integrated with good hygiene practices. Fly sprays and papers can also be used to control adult flies. All our insecticide treatments are HSE approved and it is safe to return to and use the rooms that have been treated after a few hours. If you have pets, keep them out of the affected area for at least 24 hours.
In most situations it normally takes up to 60 minutes for our technician to complete their risk assessment, the required treatment and to brief the customer on the actions taken and next steps, but this can be extended if the infestation is in numerous areas or other hazardous conditions exist.
Blow Flies / Blue Bottle (Calliphoria vomitoria) Green Bottle (Lucilia spp.)
Blow flies are so called because they were believed to “blow” their eggs on to exposed meats. Adults are 6-12mm in length with a wingspan of 25mm. They are a dull metallic blue in colour and their larvae grow to 18mm and are pale yellow to white in colour. Their Pupae are approximately 10mm and a dull mahogany brown.
Cluster fly (Pollenia rudis)
These are large flies (10mm long), with a shifting pattern of silver and grey-brown markings on the abdomen, and crinkly yellow hairs on the thorax. The larvae live as parasites inside earthworms. Eggs are laid in the soil and hatch in about a week. The young larvae bore into worms where they stay throughout the winter. In spring the larvae develop quickly, usually killing the worms, then pupate in the surrounding soil. The adult flies emerge in summer.
Crane Fly “Daddy Long Legs” (Tipulidae oleracea)
Adults Crane flies are very slender, long-legged flies that may vary in length from 20-60mm. Their larvae are known a “leatherjackets” and are about 25mm long and have a grey/brown leathery skin.
Rat-tailed Maggot/Drone Fly (Eristalis tenax)
Adults grow up to 20mm long with a tail-like breathing tube 30-40mm long and grey in colour. It’s body is brownish to black, fairly hairy and the thorax has a yellowish tint and vertical stripe. The drone fly is up to 15mm long and resembles the honey bee in action and appearance, but has only one pair of wings.
Filter Fly (Psychoda sp)
Adults are 2mm, with almond shaped, hairy wings which are carried at a roof-like angle in flight. Adults are small and very hairy, with a pair of pointed wings. They are frequently mistaken for small moths since the wings are held roof-like over the body when at rest. They are weak fliers and often appear to be jumping or hopping. Flight and mating activities normally occur in the evening hours when they are attracted to lights.
Fruit Fly (Drosophila spp)
Adult Fruit flies are very small insects, about 3mm in length with a usually a light yellow to tan body colour. A distinguishing feature is their red eyes. Fruit flies are weak fliers.
Lesser House Fly (Fannia canicularis)
Adults are 6mm long with 12mm wingspan. They have a grey thorax with 3 faint longitudinal stripes, with the base of abdomen having an extensive yellow patch. Larvae are about 1.5mm long when newly hatched and 5-8mm long when mature, pale brown in colour, ovoid in shape with whip–like protuberances around the edges. At rest, wings are folded along the abdomen.
Phorid/Scuttle Flies (Family Phoridae)
Adults are up to 3mm in length, including the wings. Black, brown or yellowish in in colour, with a humpbacked shape thorax. The phorid fly breeds and feeds primarily on moist decaying organic matter and the adult flies have a characteristic habit of scuttling in a fast run instead of immediately taking to the wing when disturbed.

- Sweep up food spillages immediately and don’t leave uncovered food lying around.
- Regularly clean under kitchen units, appliances and in any other areas where food debris and grease can build.
