It is sometimes hard to believe that small insects have lodged in your house. And yet, it has been observed that some species tend to take up residence each year in Quebec homes. While some insects aren’t as bothersome, others can cause real problems.

But what species are most often found inside our homes?

Insects most often found at home


In Quebec, there are different kinds of ants, including carpenter ants, odorous ants and pharaoh ants. They can enter our homes through small cracks located in the foundations. They tend to dig tunnels for nesting, which can cause considerable issues in maintaining the structure of the house.

It is therefore necessary to put in place solutions that get rid of ants and prevent them from settling in comfortably.


Generally, pet owners are more likely to have fleas inside their home. Indeed, they usually slip into the fur of your animals and swarm quickly, making them difficult insects to displace.

In addition, with winter temperatures, this insect will especially appreciate the warmth of your home so it can thrive before sunny days return.

Bed bugs

Very common in Quebec, bed bugs move through clothing and luggage. Thanks to this mode of transport, this biting insect can quickly contaminate a home and become a health risk if the infestation grows.

It is essential to treat the problem as soon as possible to ensure the extermination and decontamination of the premises.


If there are many insects in your house, it is quite likely that spiders will be tempted to stick around since they feed on other insects. In addition, houses are an ideal place to find protection from the outside world (natural predators, bad weather, climate, etc.).


Cockroaches feed on just about anything they find in your home. They appreciate the warmth and humidity found in your home. The problem with these insects is that they leave a bad smell and are very difficult to exterminate. A professional is often required to implement the most appropriate extermination strategies for this type of infestation.


Earwigs can appear in your home in the summer, usually between June and July. Most of the time, their presence is accidental as they feed on things in your garden, such as aphids and insect larvae.


Mites are invisible to the naked eye. Nevertheless, they can be almost everywhere in your home and resist all temperatures. They are most often present in the dust particles that circulate in your home.

Are these arthropods harmful to our homes?

Not all insects are harmful to humans or your home, such as earwigs and spiders that only feed on decaying plant material. However, some of them can transmit serious diseases, develop allergies, weaken the structures of the house, furniture and wooden floors, affect the cleanliness of a building and damage your plants.

These arthropod pests include cockroaches, ants, fleas, bed bugs, and mites. If you want to avoid any risk, it is recommended to get rid of them as quickly as possible.

How to get rid of them

Various methods exist to get rid of pests. Depending on the type of insects present or the size of the infestation, extermination strategies may differ.
