Fruit flies
Fruit flies are common in kitchens and can be an annual problem but are most prevalent in the summer months as they are attracted to ripened or fermenting fruits and vegetables. Adult fruit flies are approximately 3-4mm long and have red eyes, and a tan and black coloured body. They will lay their eggs close to the surface of rotting produce and other damp, organic materials. Fruit flies can also breed in drains, bins, and areas where there is rotting substances. When the larvae emerge, they will continue to feed on the surface of the fermented foodstuffs. Given the opportunity, the fruit fly could lay approximately 500 eggs. The life cycle from egg to adult is around 1 week. To prevent fruit flies it is important to eliminate the source of where they are breeding. This can be done by disposing of over ripened foods, cleaning spillages, and cleaning bins regularly.
Cluster flies
Cluster flies are an extremely common household pest that appear in early winter and spring and can be a nuisance as they buzz around in clusters, hence the name. they are approximately 8-10mm in length and are covered in short golden hairs on the thorax. Cluster flies live outdoors during summer and will lay their eggs in soil. When the Autumn months approach and the temperature drops, cluster flies will invade homes to seek warmth. They favour lofts, attics and roof spaces and enter by squeezing through the tiniest gaps in walls and roof tiles. You can cluster-fly proof your home by sealing window frames, doors, and other entry points, although it is recommended to use a combination of insecticides to manage the numbers.
Drain flies
Drain flies thrive in stagnant water, especially water that is shallow and near sources of food or bacteria. They are approx. 2-5mm in size and congregate around stagnant water. The drain fly is grey in colour and have small, rounded wings. They harbour in areas that are not frequently used, such as sinks, showers, and cellars. Drain flies are completely harmless as they do not bite humans or transmit disease. If you are noticing drain flies in your property, it may be worth locating the source and giving the area a deep clean. They are simple enough to eradicate.
