Small fly management for homes

This situation has happened to almost everyone. You are on the sofa reading a book or enjoying a snack and suddenly one (or several) flies come to bother you. Luckily for you, this problem is quite common and there are several ways to get rid of annoying flying insects that invade your house. In this article, we tell you how to get rid of small flies in your home.

Common small flies in homes in Canada

Here are the most common species of flies that are found in homes in Canada:

  • Cheese flies?
  • Cluster flies?
  • Drain flies?
  • Fruit flies?
  • Houseflies?

Cheese flies

This type of fly (Piophila casei) is 2.5 to 5 mm long and is black or bluish in color. Its lower part of the head and legs are yellow. It has a broad head, long wings, and the back of its thorax has three rows of bristles. Its larvae are white and worm-like and measure about 5 mm long. 

One of their main characteristics is that they can jump at full speed, because of their catapult-like legs. They are capable of jumping up to 25 cm horizontally and 15 cm in height. Concerning its life cycle, it can be completed in about 12 days. Adults and larvae of this species feed on decaying organic substances and can therefore be carriers of pathogenic microorganisms.

Cluster flies

This fly feeds mainly on earthworms. They are dark gray or silver, have short golden hairs and do not have distinctive stripes like other fly species. They have a wide and robust appearance. The size of cluster flies (Pollenia rudis) is approximately 8 mm long.

Drain flies

Drain flies (Psychodidae) are often associated with sewage sludge, where the larvae feed on settled organic material. They are 2 mm long and have a light brown-gray body. Its wings are densely covered with fur and are held open like a curtain over the body in a resting position.

Fruit flies

This species of flies (Drosophila melanogaster) has a yellow-brown color with bright red eyes. The female fruit fly can lay up to 500 eggs and they reach the adult stage in about 7 days. Adult fruit flies reproduce in fermented fruits and vegetables. During the larva stage, they feed mainly on bacteria and yeast found on decaying fruits and vegetables.


Houseflies are great carriers of disease and can infest all types of premises. They are attracted to all kinds of food sources, including food intended for human consumption, animals, animal feed, food waste, and even feces. Once inside, houseflies can be found on walls, floors, and ceilings. Outside they can be seen on plants, soil, fences, compost piles, and trash cans.

Where do these flies breed?

Flies breed in crumbs, damp vases, garbage cans, ripe fruit, or near wet areas caused by water leaks. Flies that breed indoors are often inconvenient and multiply rapidly when not dealt with quickly. Fruit and vinegar flies are a cause for concern, as they can contaminate your food by laying their eggs in the food you eat.

How fast can they develop?

Flies develop rather fast, as their life cycle can be completed in under 2 weeks. The flies lay the egg and it takes 8 to 20 hours before hatching. The larva then appears, and after 10 days, the fly larva produces a reddish covering layer, which remains for another 3-6 days until they reach the pupal stage. Once the pupa hatches, the adult flies are ready and able to start flying freely as they’ve reached full maturity. They are destined to survive for no more than 20 days after that.

What causes small flies in homes?

Small flies are attracted to the warmth of your home and the smell of potential nutrition sources. It only takes an open door or window for one of them to make its way in. Then, houseflies are so fertile that they are capable of laying up to a thousand eggs in a few days. Another point of intrusion houseflies exploit is the fruits you buy at the grocery store. If only one of these fruits is fermenting, an opportunistic fly will make it the nest of its eggs.
