Pesticide Use

The City of Kamloops is a leader of Integrated Pest Management (IPM). In our practice of IPM, we only use chemical pesticides as a last resort, and only after following all of IPM steps. 


  • 2001: the City adopts a citywide Integrated Pest Management (IPM) Master Plan. The plan lays out a strategy for responsible pest management in public and private green spaces.
  • 2006: the City forms a pesticide use committee to research pesticide bylaws and alternatives to chemical-based pesticide control. The committee, comprised of various groups and agencies in the community, provides recommendations to Council on the future of pesticide use in Kamloops. 
  • 2008: the City launches the Healthy Landscapes, Healthy Living education campaign.
  • 2010: the Pesticide Use Control Bylaw comes into effect.
  • 2015/2016: New bylaw

Frequently Asked Questions

What are pesticides?

Pesticide is a term that broadly refers to all formulations that are used to prevent, destroy, repel, attract or reduce pest organisms. Some of the more commonly known pesticides are:

  • Herbicides (for plants)
  • Insecticides (for insects)
  • Fungicides (for fungus)
  • Miticides (for mites)

Some pesticides are considered higher-risk and others are deemed lower-risk (commonly used by organic farmers). Read our Pesticide Bylaw Resource Guide for more information.

What are the exceptions?
  • excluded pessticides
  • fruit tree and vegetable gardens
  • noxious weeds and insects (as defined in the by-law)
  • hard landscapes (e.g. patios and sidewalks)
  • agricultural land and farms
  • greenhouses
  • mosquito control and other pests that transmit human disease
  • pests that impact agriculture or forestry
Why is there an exception for ftuit trees and vegetable gardens?

There are limits as to what City Council can regulate.  It only has the authority to regulate the use of pesticides on ornamental trees, shrubs, flowers, and turf on residental properties.

What is Integrated Pest Management (IPM)?

IPM is an approach that uses a combination of techniques to control weeds, damaging insects or disease, and other nuisances in an effective, economical, and environmentally sound manner.

The five steps of IPM are:

  1. Identify if there is a pest and what it is
  2. Monitor for the amounts of damage
  3. Determine acceptable injury level
  4. Treat with a method that is appropriate
  5. Evaluate success
What are excluded pesticides?

Excluded pesticides = ALLOWED pesticides.

City of Kamloops residents may use allowed pesticides containinly only the active ingredients listed on the Excluded Pesticide list.

What are noxious weeds and invasive plants?

Invasive alien plants are non-native plants that have found their way into a region that they would not naturally be found.  Noxious weeds are an invasive plant that is designated by regulation to be noxious.  See the complete list of noxious weeds and invasive plants as designated by the Southern Interior Weed Management Committee.

What is the City doing?

Ornamental Trees, Shrubs, & Flowers 

The City practices good plant health care to prevent pest problems and follows IPM when a pest problem arises. Only ALLOWED pesticides may be applied on City trees, shrubs, and flower beds.


The prohibition does not apply to turf on City lands. The City has a thorough turf health program, and practices IPM. Chemical pesticides are only used on premier Sports Field turf and are only used as a last resort after going through all other steps in the IPM process. 

Since the by-law does not apply to hard landscapes, the City can and does use pesticides on areas such as sidewalks.

What can I do with unused pesticides?

Unused domestic pesticides may be taken to a Paint Plus Depot such as the Mission Flats Landfill.  If you have a jug of something you are not sure about you may take it to a free drop-off event such as the City Hazardous Household and Electronic Waste Drop-off event.
