What are cluster flies attracted to?

However, unlike some of their other fly relatives, cluster flies do not carry dangerous diseases and they do not bite humans or animals. There’s also no risk of these pests laying eggs in your home and causing an infestation.
Do cluster flies kill earthworms?
Soon the eggs hatch and the tiny maggots dive down into the soil. Once sated, the cluster fly larva pupates in the soil, later emerging as a new adult fly. Other species of cluster flies attack earthworms and snails, and there is evidence that some cluster flies may go after certain insect larvae in the soil.
Why do I have so many cluster flies?
A warm autumn day might cause cluster flies to “bug” you around the house. In search of sunny sides of homes to escape the cold, the over-wintering pests crawl out of wall voids and attics to enjoy the warmth, clustering in large numbers on the sunny exterior of buildings, as well as at windows within the home.
How do I stop cluster flies returning?
It is not unknown for previous generations of Cluster Flies to leave a scent to allow the Flies to follow and return to the same place the next year. This can be removed through the use of a strong disinfectant around eaves, soffits etc as this will mask the scent. This should prevent flies returning year after year.
Do cluster flies ever go away?
Cluster flies typically return year after year, unless eaves and other entry ways are adequately sealed.
Do cluster flies come back every year?
The flies tend to return to the same property year after year. Even if there are similar buildings nearby, they may not be affected. The good news is that although you may be unfortunate and have invasions of cluster flies every year, control is fairly easy.
What is the difference between house flies and cluster flies?
SIZE AND COLOR: Cluster flies are larger than house flies at approximately 7mm long compared to the 3-6mm length of a house fly. WINGS AND FLIGHT: Cluster flies will fly at a much slower and less frantic rate than a house fly. Cluster fly wings will overlap while at rest, house flies have wings that remain separate.
How do you get rid of cluster flies naturally?
You can also use some home-made sprays against cluster flies to create an unwelcoming atmosphere around your trash bins. Citronella sprays or natural insect repellents are useful sometimes if you don’t want to spray chemicals. A strong vinegar solution discourages them from hanging out around trash bins as well.
What is the life cycle of a cluster fly?
The cluster fly larva will use the earthworm for food until it completes development, which can last for 2 to 3 weeks before it pupates. Cluster fly pupae mature into fully developed adults in 11 to 14 days. The entire cluster fly life cycle generally takes 25 to 39 days to complete.
Where are cluster flies coming from?
If the temperature inside the building is manually controlled above 12 degree Celsius, the cluster flies may come out thinking it is spring. Cluster flies are strongly attracted to light, so you can also find them near windows and near lamps at night.
Where do cluster flies lay eggs in houses?
Female cluster flies lay eggs in cracks, crevices, and openings in the soil. Eggs hatch in three days.
Where do cluster flies lay their eggs?
The cluster fly maggot is an internal parasite of earthworms and the flies are among the first to be active in the spring. They can be observed buzzing around yards just above the ground. They lay their eggs in cracks in the soil and the eggs hatch in about three days.
Do cluster flies have maggots?
Adult cluster flies feed on nectar. The larvae, also known as maggots, are internal parasites of earthworms. Each female cluster fly lays her eggs in the soil. After a few days the eggs hatch into larvae.
Why are flies swarming my house?
What Attracts Flies? House flies feed on decaying organic material and waste, which includes kitchen garbage, pet waste and even animal food. For this reason, you will often see flies swarming around trash cans, outdoor restrooms and outdoor animal enclosures.

Do cluster flies go away in the summer?
Once the weather warms in the spring, at about 12°C cluster flies start to become active again. The adult flies will eventually leave in late summer to lay their eggs in soil. The cluster fly larvae are parasitic on earthworms and will pupate in the soil, emerging as adults ready to find shelter for the winter.
