Anyone can have cockroaches regardless of social class or origin. There’s no need to be ashamed if this happens.
According to investigations conducted by Montréal’s public health department, in 2018, about 3% (22,000) of households in the city had had cockroaches.
It’s important to stay vigilant and act quickly to prevent cockroaches from spreading. Don’t treat your home yourself: call on a professional. If you’re a tenant, the owner is responsible for taking care of the problem.
When to Consult
Protection and prevention
Cockroach debris (excrement, decomposing insect shell, etc.) are allergens that can cause or aggravate asthma and hay fever (allergic rhinitis).
More rarely, a cockroach infestation can result in transmission of bacteria through contaminated food.
Having cockroaches can cause anxiety and sleep disorders.
Tips to prevent infestations
To reduce the probability of infestation and increase effectiveness of extermination products, it’s important to make the environment the least attractive to cockroaches as possible. To do so, access to food and water must be reduced. Here are a few tips to follow:
Occupants or tenants
- Regularly clean food deposits from surfaces and grease spots from appliances.
- Don’t leave dirty dishes on the counter, especially at night.
- Keep food in sealed glass or plastic containers. Cardboard and paper aren’t cockroach-proof.
- Don’t leave your pet’s food or water bowl out.
- Put garbage in containers with tight fitting lids and throw them out regularly.
- Clean your home thoroughly, including places difficult to reach (behind the stove and refrigerator).
- Notify the owner quickly of the infestation.
- Before the extermination, prepare your home according to the professional’s recommendations
Owners or building managers
- Make sure building garbage bins are covered and surrounding areas clean.
- Repair water leaks to reduce availability of water.
- Seal and fill holes and cracks in the building.
- Restrict the movement of cockroaches between apartments by installing rubber seals under outer doors, and fine-mesh screens on conducts.
- Call a certified pest control specialist as soon as you’re notified that there are cockroaches in an apartment, and allow the professional to proceed to solve the infestation problem.
