2014 Integrated Pest Management Plan

Read the 2014 Integrated Pest Management Plan (PDF, 4.9 MB) to learn about pest control issues, outlines current pest management programs and recommendations for future initiatives.


Before undertaking control measures to deal with pest populations, Parks Operations follows an Integrated Pest Management (IPM) approach.

This approach uses monitoring and survey programs to identify the type and population of pests. It ensures an appropriate response is chosen. IPM also uses education to proactively deal with pest outbreaks.

The basic IPM process follows these steps:

1. Inspection/Monitoring:
The pest is located on site, either as a result of a systematic monitoring program or as an already-established new infestation.

2. Identification:
Both pest and host must be correctly identified before a control program can be chosen. 

3. Threshold Limit Evaluation:
A threshold limit is the level at which a pest's population is hazardous to the host's health and/or the aesthetic appearance of a site. It is the earliest point at which pest control of some sort is required. Some pests never do reach damaging levels (even if they can be found all across the City), thus they don't have a threshold limit.

4. Control:
Once the threshold limit for that pest is reached, an appropriate combination of controls is selected that will reduce pest populations with the least risk to the public and environment at the least cost.  This may include cultural, physical, mechanical, biological or chemical controls.

5. Evaluation:
After control is complete, the IPM operation is assessed  and changed as needed. By monitoring remaining and rebound pest populations, control strategies can be fine-tuned over time to save time and money while remaining effective.

6. Education & Prevention:
The most important step of IPM.  Educating individuals and organizations is an important part of the IPM process. IPM utilizes a holistic approach to pest control and this includes factors such as:

  • Hardy or disease resistant plant selection
  • Beneficial cultural practices
  • Environmental stewardship
  • Prevention of pest problems through excluding either pest or host 

We encourage homeowners to get involved and learn about their pest problems. Find out where pests may want to live in your yard and what cultural controls you can use to make pesticides unnecessary. It's an opportunity to get your kids involved with nature and interested in what makes plants grow!
