Weed & Pest Management

Integrated Pest Management

Integrated Pest Management (IPM) is a decision-making model used to prevent and manage pest problems. IPM promotes the use of various management practices (cultural, biological, mechanical, chemical, legal, and genetic) to improve plant health, and to prevent and manage pest infestations. 

Originally created in 2008, the plan was updated and accepted by Okotoks Town Council in 2016. The updated plan provides strategies and goals for the management and maintenance of weeds, nuisances, pests, and animals within Okotoks. The plan aligns with federal, provincial, and municipal acts, regulations, and bylaws.

Current Approach to Dandelion Management

Okotoks aspires to be innovative and resilient, balancing community expectations with impacts to the environment. In 2008, Okotoks led the initiative of utilizing weed threshold levels to justify spraying, allowing for some tolerance of weeds in parks and open spaces. The Town’s Integrated Pest Management Plan was again updated in 2016 and reflects all our current practices for the management of weeds and pests on public lands. 


The Town’s Integrated Pest Management Plan was again updated in 2016 and reflects all our current practices for the management of weeds and pests on public lands.  Manicured turf areas are treated with herbicide by certified pesticide applicators only where total weed coverage exceeds 15% in park areas, 5% in sports fields and high profile sites.  In 2016, the Town asked residents through its Conservation Educator Program whether they supported this practice. Of the 408 residents they asked, 327 (80%) were in support. Since incorporating threshold weed spraying other municipalities have followed suit. 

As dandelions are considered a “nuisance” weed due to its stronghold across North America, control is the only expected outcome and eradication not currently possible. However, by controlling weeds on public lands, homeowners have less of a need to purchase and apply these chemicals themselves.  Where citizens wish to not have herbicide utilized in their neighbourhood park, the Integrated Pest Management Plan makes a provision for that requiring neighbourhood support on that decision.

In Okotoks, water conservation is a priority and most parks and open spaces are non-irrigated, except for sports fields. Lack of irrigation coupled with generally low precipitation prevents turf from being able to outcompete weed species such as dandelions.


The Town acknowledges the importance of pollinators and does not use neonicotinoids, the pesticide family that has been determined to contribute to increased bee mortality. Although dandelions do provide early food for pollinators, there are a number of other early bloomers that assist here such as buffalo bean, Saskatoon berry, poplar, native willow, aspen, and Canada buffaloberry. These species are abundant in our natural areas including the river valley of which comprise over 260 hectares within our Town boundary, exceeding the land area of manicured turf on public lands.

In addition, the Town has a number of new initiatives underway to improve pollinator habitat. Where some narrow or steep turf areas exist, the Town has replaced traditional turf with a combination of pollinator friendly plants and ornamental grasses.  These plantings not only improve the aesthetics, but eliminate the need for mowing and herbicide use.  Some examples of areas where this has been undertaken include Sheep River Boulevard, Southridge Emergency Services site, Operations Centre, Crystal Green Drive median, and the Big Rock Trail median. In 2017, many pollinator plants were incorporated into the re-landscaping of Veterans Way.  We will be expanding this initiative by incorporating these practices into new subdivision areas. Residents can also get authorization from the Town to convert turf boulevards adjacent their property to mulches or alternate groundcovers in a similar fashion.

The Town of Okotoks will continue to be proactive and innovative in our design, maintenance, and management of public lands to develop a resilient and beautiful community. Okotoks continually reviews best practises and looks for opportunities and innovative ways to reduce any impacts to the environment.

Mosquito Q&A

​Q: Does the Town of Okotoks have a mosquito monitoring and control program?

A: Yes, mosquito larvae are sampled and controlled in surface waters on public lands.

Q: What is the control method used for mosquito control?

A: A biological control agent is released into the water to control mosquito larvae. The product is the dead spores of Bacillus
, a natural soil bacterium.

Q: Is chemical fogging of adult mosquitoes performed?

A: No, the Town does not fog adult mosquitoes.

Q: Will aerating storm ponds reduce mosquito populations?

A: No, storm ponds have extremely low mosquito larvae populations already that they currently do not require treatment.

Q: If not storm ponds, where do mosquitoes come from?

A: Roadside ditches are the main culprit for harbouring large populations of mosquitoes and other small stagnant sources of water are the main sources of mosquitoes.

Q: Is West Nile Virus a concern for Okotoks?

A: The threat of people contracting West Nile virus is low in central Alberta. Mosquitoes that carry West Nile Virus require a longer warmer season than is typical in this region, however, a long, hot summer can increase the risk.

Q: What can residents do to help?

A: Ensure no standing water is left in yards such as spare tires, plant trays, pails, blocked swales, etc. Ensure water is refreshed in rain barrels and bird baths regularly.
