2024 Mosquito Control

Practices & Products 

The City of Steinbach will continue with its larviciding program this year. An environmentally friendly product called VectoBac is used, a granular substance distributed by hand or with a backpack blower. The larvicide is safe to humans, pets, fish, and most other insects, including dragonflies which play an important role in keeping the mosquito population lower. Larviciding will be conducted within a 2 km buffer zone of the city. Larviciding is one of the most effective control measures used to reduce mosquito populations. The City will larvicide throughout the summer as needed depending on stagnant water and rain. 

The public will be provided with 24 hour notice of any fogging event to occur. 

The City may conduct adult mosquito control (ground-based ultra low volume fogging) in 2024, if the number of mosquitoes counted in Steinbach reach and stay at a high level. Fogging would occur from streets and road allowances, and in parks and green spaces within city limits. 

Presuming weather conditions are conducive, the ground based fogging would occur during the late evening and night. Fogging may occur twice in seven days. If fogging is cancelled due to weather conditions, adult mosquito control would be carried out as soon as weather permits. 

The pesticide product to be used for ground spraying is Malathion dispersed by an ultra low volume aerosol sprayer. To reduce exposure during fogging: 

  • close all windows and doors; 
  • stay away from working trucks while spraying is underway; 
  • supply/exhaust fans and HRVs should be turned off; 
  • ensure fruits and vegetables are washed; 
  • remove clothes and children’s toys from outside areas; 
  • wash any household items or toys left outside before use. 


The public may send written objections to fogging by mail to the addresses below, by e-mail to, or in person at City Hall, 225 Reimer Avenue in Steinbach. Objections should be dated and must include a name, street address, and phone number and will be kept on record for the 2024 year.

Please note, if you registered an objection to fogging last year (2023), you will need to register again this year. As per the Manitoba pesticides regulation, objections must be filed each year. Any objections received less than two days before a scheduled fogging will take effect for the next fogging. 

What You Can Do 

The City reminds residents that they can also take actions to help keep the mosquito population down: 

  • Eliminate standing water. 
  • Regularly clean and empty eavestroughs, pool covers and other items that collect water. 
  • Clean and empty bird baths weekly. 
  • Make sure openings in rain barrels are covered with mosquito screening or tightly sealed around the downspout. 
  • Clear your yard of old tires or other debris where water collects. 
  • Cut the grass around your home; trim hedges and trees around doorways and seating areas.
  • Use insect repellants.

Dutch Elm Disease

A single piece of firewood can destroy millions of trees.  It might seem difficult to imagine, but something as simple as bringing your own firewood when you travel to or from your favourite campsite could threaten and destroy thousands, even millions, of trees. Transportation of firewood is a common way for invasive species to spread. Hidden under the bark where you can't see them, these posts are moved across Canada.  

Stored Elm wood is a breeding ground for Elm Bark Beetles. Dutch Elm Disease is a fungus carried by these beetles. For this reason, it is illegal to store or transport Elm wood in Manitoba. All stored Elm wood spreads Dutch Elm disease by breeding Elm Bark Beetles.

If you have stored Elm wood, please bring it directly to the Steinbach Landfill at 104 Hanover Road E. for proper disposal.
