Cluster flies are dark grey with overlapping wings, and they measure approximately 8mm long. Their bodies have a mottled appearance with short golden hairs on the thorax. Cluster flies do not lay eggs on human food but instead use earthworm burrows, where the larvae then infest the worms.

They are renowned for hibernating in large numbers during the autumn months, entering buildings through small holes in the walls and preferring cavities, roof spaces, attics, and dormant rooms in which to overwinter. They appear again in the spring, often congregating at windows and flying slowly around the home.

House flies and bluebottles are most commonly found in the UK. House fly larvae are white, tapered and up to 12mm in length when mature, with the adult flies measuring 5-8mm. They lay their eggs in batches of 120-150, which can hatch into larvae in hours, and are particularly fond of decaying vegetable matter. Bluebottles have larger larvae and adult flies which measure up to 18mm and can be identified by their metallic blue bodies. They can lay up to 600 eggs, which will become fully developed maggots within a week. The maggots feed on meat, especially dead rodents or birds, before emerging as adult flies.

Cluster flies are important to eradicate because they will return in large numbers year after year if not properly removed. Contact Landcare Pest Control to solve your pest problem.

When flies invade your home or business it is a serious matter.  Flies differ from most other insects in having only one pair of wings.  The remaining pair has evolved into a remarkable balancing device that helps flies to be skilled and efficient ‘pilots’.

Most flies feed by vomiting onto the surface of some food, then using their long and specialised mouthparts to suck up the softened or liquefied food surface. Each time the fly vomits, it brings up some bacteria and particles from its previous meal, which could have been rotting meat, human or animal faeces and so on.

You can see just how easily flies spread disease by this practice and through contaminated particles carried on their feet and bodies. In this way, food poisoning and a range of other diseases can be quickly spread by the local fly population.

It is particularly important to keep food preparation areas free from flies and this is not always straightforward in some houses. At certain times of year, some species of fly will invade homes in large numbers, and this is best dealt with by a professional pest control contractor.

Flies are one of the largest insect orders after beetles, and their transmission of diseases that can infect our food makes them unpopular. It has a four-stage life cycle, from eggs to maggots, and pupae to adult flies. Taste sensors on the feet of house flies help it to detect its food, which it eats by vomiting saliva onto the surface and then sucking up using its sponge-like mouth. This contaminates the food with bacteria; flies can transmit food poisoning and other diseases such as cholera and typhoid.


Keeping bins regularly disinfected and sited away from windows and doors helps to discourage these unwelcome intruders. Food should be stored under cover or kept in sealed containers and surfaces regularly wiped down. Even tiny crumbs or drops of spilt liquid can be an attractive meal for flies.
