Mosquito Control Program

Mosquitoes are blood-thirsty pests that thrive during wet, warm conditions. Since it takes just a cup of water to breed hundreds of mosquitoes, huge swarms can live in the thousands of sloughs, ponds, puddles and other bodies of standing water in and around Regina. The City has a Mosquito control program to battle and reduce the number of these pests.

Step 1 - Monitoring Bodies of Water

Monitoring mosquito larvae Crews take samples from water bodies in the city and up to 10 km outside city limits to check for mosquito larvae. If numbers of larvae are found, the City treats the water.

Step 2 - Treatment

The City uses a special bacterial agent called Vectobac ™ to kill mosquito larvae in ponds, lakes, sloughs, ditches and puddles. Although Vectobac is harmless to pets, fish, wildlife, beneficial insects and humans, the City posts pesticide advisory signs in treated areas as part of its integrated pest management strategy.

Step 3 - Monitoring Populations

The City monitors adult populations by hanging light traps in different areas of Regina. Staff empty the traps daily and count the number of trapped adult mosquitoes of each species. The City uses this information to track population trends and for forecasting.

Step 4 - Public Education

The City advises the media and the public about our mosquito control program and tells everyone what they can do to help control mosquitoes.

The Buzz on Bugs

The Buzz on Bugs is your weekly update on all things mosquitoes during the summer. We use an environmentally friendly and preventative program to control the pesky blood suckers so you can enjoy the outdoors.

The City has 12 traps set up across the city to monitor mosquitos. The city is broken down into six monitoring areas. Each area has two traps. The information you’ll find here is based on the number of mosquitos found in each of the 12 traps on a weekly basis.

Historical Comparison 

When we compare mosquito counts, we are talking about averages of the counts found in the City’s 12 traps. We add up all the numbers of mosquitoes found in the 12 traps and divide by 12 to get the average (mean count per trap).

The blue line in the graph below shows you the historical average based of mosquito counts in traps from 1986 to present. This average includes years when there was very little to no mosquito control (1986-1992), years when there was a base mosquito control program (1993-2003) and years when the mosquito control program was enhanced (2004-present).

The red line on the graph shows us how we are doing right now. It represents the Mean Count per Trap for the current year. When the red line is below the blue line, we are winning the battle against high mosquito numbers. When the red line is above it, we have some more work to do.

This is our final report for 2018:

Counts Within & Outside City Areas

Want to see how your area of town compares to others for mosquito counts per week? Want to see how we’re doing this year compared to last year? Check out this table.

We’ve included weekly mosquito counts from traps set up in each of the City’s six areas. You’ll find counts from two traps set up outside Regina in rural areas - one north of the City and the other east of it. Now you can determine how we’re doing within the City to control mosquitoes with our pest control program.
