Are Pesticides allowed in Longueuil?

The application of pesticides (insecticides, herbicides and fungicides) is forbidden throughout Longueuil for all residential, commercial, and industrial areas. This by-law is aimed at protecting the environment and the health of residents from any harmful effects that pesticides may have.

The by-law encourages healthy cultivating practices, alternative solutions and the use of low-impact pesticides.

Only some low-impact pesticides may be applied in sensitive zones and on land close by: public land, parks, green spaces, daycare centres, schools, churches, and health centres.

The application of low-impact pesticides does not require a permit. However, the directions on the product's label must be followed.

In a case of infestation that could affect human health, animals, or plants, and having shown that all the alternative solutions have failed, the city can issue a permit to the owner of a property for the application of a pesticide by a contractor registered with Ville de Longueuil. This permit is free and is valid for a period of 10 days.

Please follow the procedure set out below:

  1. Verify with the contractor that he's registered with Ville de Longueuil (the registration should be visible in each vehicle).
  2. After having shown that all the alternative solutions have been exhausted, the contractor must apply for a permit to use pesticides. This application must be signed jointly by the owner and the contractor; the contractor is responsible for submitting the request to Ville de Longueuil. The permit application form is available from the registered contractor, or it may be downloaded directly from the following link: Permit application form. It's free.
  3. Ville de Longueuil will either grant or refuse the permit to the contractor within 24 hours after having received the request.
  4. Permits to the owner will not be granted if the contractor is not registered with Ville de Longueuil.

What are Pesticides?

Pesticides include all substances and micro-organisms used to directly or indirectly control, destroy, lessen or ward off any organism that is considered to be undesirable. The most common pesticides are:

Category of Pesticide and target
Herbicides: weeds
Insecticides: insects
Fungicides: fungus growths (microscopic mushrooms)
Rodenticides: rodents (rats, mice)

Numerous scientific studies indicate, despite some reserves, that long-term exposure to pesticides risks increasing the possibility of creating disorders in the reproductive, hormonal, immune, or nervous systems. Certain pesticides may also induce teratogenic or cancerous effects. Source: Report of the Study Group on Pesticides in Urban Areas, March 2002

Can I Use Low-Impact Pesticides Myself?

You may apply pesticides yourself if you have properly identified the problem (and you know its habits), established that it is important enough to be a nuisance, and that it can be treated with a low-impact pesticide. If not, it is preferable to call upon a qualified contractor.

If you use a low-impact pesticide:

  • Be sure that you have correctly identified the source of the problem as well as its habits. Use an appropriate remedy. An intervention when the ravager is hard to reach will not yield good results and will end up being a waste of time and energy.
  • Read all the instructions on the product label and observe them scrupulously.
  • Remember that undesirable insects and plants are not a problem as such, but rather an indication that the culture you are trying to establish is out of balance or under the wrong conditions.

Reducing the Use of Pesticides

Pesticides should only be used as a last resort. By using appropriate gardening methods to provide a proper environment for the plants and lawns, they will be healthier and less vulnerable to outside stress. It is also important that we become more tolerant to the presence of certain plants, insects, animals, etc. that we judge to be a nuisance, but which do not affect our quality of life or our health – contrary to certain pesticides that we use to control them.

Alternative Methods

Hints for reducing the use of pesticides:

Increase your tolerance towards undesirable plants

Create more bio-diversity in your lawn (clover, rye grass, fescues, endophytes, etc.) could help you avoid serious damage to your lawn.

How to Convince your Neighbour or a Sceptical Property Owner

  • Explain your concern about effects on your health and on the environment.
  • Set an example by maintaining a good-looking lawn without using pesticides (it is possible!).
  • Be tactful by attacking the problem and not the person.
  • Obtain information and share it with other people.

Choosing a Good Contractor

  • He or she will analyse the situation by visiting your property.
  • A good contractor will inform you and propose natural preventative methods for obtaining a dense, vigorous lawn.
  • He or she will use fertilizer that is 100% natural.
  • He or she will use alternative methods and low-impact products.
  • A good contractor will not offer pre-determined pesticide applications (4 systematic treatments per year).
  • A good contractor will make an inspection of your lawns, etc. before submitting a proposal.
  • He or she will be registered with Ville de Longueuil.
  • He or she respects the principles of integrated pest management: at the right time, in the right place and as a last resort.
    At the right time: insects and weeds have a weak point in their life cycle when pesticides, even low-impact ones, have an optimal effect.
    In the right place: unless there's a major infestation, it is not necessary to treat the entire lawn. The treatment can be applied only on the damaged area.
    As a last resort: Only after putting in place adequate and healthy cultivating practices.
