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 2026, 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; 
• fruits and vegetables are washed; 
• remove clothes and children’s toys from outside areas; 
• wash any household items or toys left outside before use.
