Welcome to our weekly dormancy tracker for Manitoba, Canada, for the week of October 12, 2026. This week, we are firmly in a state of **Dormant. ❄️ Dormant.** across the entire province. The cooler temperatures have effectively put an end to outdoor biting insect activity, a trend that’s been subtly shaped by a drier-than-usual autumn, with roughly 50mm of rain, keeping potential Manitoba bug bites slightly below typical levels before the freeze. As temperatures continue to drop, this page transitions from a bite forecast to a dormancy tracker, providing seasonal local information on frost, indoor pests, and next-season preparations for specific regions, and we will restore full bite forecasts as soon as overnight lows and daytime highs warm enough.
In Northwest Manitoba, the region is dormant with daytime temperatures around 4.1°C and overnight lows holding steady at 4.1°C. These consistently cold conditions mean that mosquitoes and other outdoor biting insects are completely inactive.
Northeast Manitoba is experiencing even colder temperatures, remaining dormant with a frosty -3.9°C both day and night. This deep chill ensures no outdoor insect activity whatsoever.
Moving to Southwest Manitoba, the area is also dormant, with daytime highs around 3.2°C and overnight lows mirroring that at 3.2°C. These temperatures are well below the threshold for any outdoor biting insect activity.
Finally, Southeast Manitoba is dormant this week, with daytime temperatures around 5.0°C and overnight lows near 4.5°C. While slightly milder than other regions, these temperatures are still firmly in the dormant range for all outdoor biting insects, and Just Bite Me temporary bug bite relief is still at retailers across Manitoba for leftover indoor bites, travel, and next season.
🗺️ Manitoba Dormancy Tracker by Region
Manitoba bug bites are dormant across most of the region this week. Expand your region below — every city and town is still listed. Local notes are seasonal information (frost, indoor pests, next-season prep) until temperatures rebound. We re-check the weather every week.
▶Northwest NW 6 communities
Northwest Manitoba is currently around 4.1°C with 93% humidity and overcast clouds. Mosquitoes and black flies are dormant here this week; city notes below cover frost, indoor pests, and next-season prep instead of bite risk. Moisture levels have been fairly typical lately, with 50mm of rain over the past month, compared with 76mm during the same stretch last year.
❄️ DormantDauphin
Dauphin residents should begin preparing their yards for the upcoming freeze, clearing standing water from bird baths and tire piles near Vermillion Park to prevent future mosquito breeding. The slightly drier conditions over the last month, with 49.6mm of rain, have meant less recent accumulation for potential future insect habitats
❄️ DormantFlin Flon
A freeze watch is in effect for Flin Flon, urging residents to protect sensitive plants and disconnect hoses from outdoor spigots around Ross Lake. The region’s 49.6mm of rain in the past month, a decrease from last year, has reduced overall moisture levels in the area
❄️ DormantThe Pas
With overnight lows still too cold, mosquitoes won’t be active around Clearwater Lake Provincial Park until temperatures consistently stay above 10°C. This past month’s rainfall, tallying 49.6mm, indicates a somewhat drier trend compared to the previous year, impacting local water levels
❄️ DormantSwan River
Swan River homeowners might notice overwintering mosquitoes or cluster flies seeking refuge indoors, particularly in basements, as the cold weather sets in. The 49.6mm of rain recorded over the last 30 days, less than usual, has contributed to a drier landscape
❄️ DormantRoblin
For those in Roblin considering a getaway, remember that biting insects remain active in warmer southern regions, a stark contrast to the conditions around Lake of the Prairies. The past month saw 49.6mm of rainfall, a bit less than the long-term average, which has left the ground somewhat parched
❄️ DormantSnow Lake
Snow Lake residents should prioritize cleaning out gutters and checking woodpiles for ticks as part of their pre-freeze yard preparations, especially near Wekusko Falls. Local precipitation, at 49.6mm for the last month, has been slightly below average, leading to less standing water
▶Northeast NE 6 communities
Northeast Manitoba is currently around -3.9°C with 93% humidity and overcast clouds. Outdoor biting insects are inactive under these temperatures. Local notes stay in the accordion as seasonal information until nights warm up. Rainfall has tracked close to normal over the past month (50mm of rain over the past month, compared with 76mm during the same stretch last year), so today’s conditions are a fair guide on their own.
❄️ DormantThompson
Residents in Thompson are not currently bothered by mosquitoes, as these biting insects remain inactive until overnight temperatures consistently rise above 10°C, particularly around the Boreal Discovery Centre trails. The slightly drier conditions this past month, with less rainfall than last year, have also contributed to fewer standing water sources around town for future breeding
❄️ DormantNorway House
With the cold weather continuing in Norway House, you won’t encounter black flies or other biting insects, as they are completely dormant until warmer spring temperatures arrive. The area has seen a bit less rain over the last 30 days compared to the previous year, which has meant a reduction in the usual amount of temporary water bodies near Lake Winnipeg
❄️ DormantCross Lake 19A
For those around Cross Lake 19A, now is the time to prepare yards for the impending freeze; clear standing water from old tires and woodpiles near your home to prevent future mosquito breeding and tick habitats. The month’s rainfall being somewhat lower than typical has meant there’s less water pooling in these spots across the community
❄️ DormantOxford House
As temperatures drop in Oxford House, keep an eye out for overwintering pests like cluster flies and even a few mosquitoes seeking refuge in basements and attics, particularly around older homes near the Hayes River. This past month’s rainfall was lower than a year ago, which has marginally reduced the overall availability of outdoor breeding sites
❄️ DormantArborg
Travelers from Arborg looking to escape the cold might consider heading south, where biting insects are still active, a stark contrast to the current dormant conditions around Morweena. The region has experienced a somewhat drier month than usual, with less rain accumulating, which could influence future insect populations
❄️ DormantGillam
Gillam is currently experiencing a period where outdoor biting insects are fully dormant due to the cold, ensuring peaceful walks along the trails without the usual mosquito activity. This month’s rainfall has been somewhat less than what was recorded during the same period last year, potentially impacting the density of future insect hatches

About This Forecast
This weekly update for Manitoba uses current weather from OpenWeather. When daytime highs stay under about 10°C / 50°F (or nights drop near freezing), outdoor biting insects are treated as dormant and city notes switch to seasonal information instead of a bite forecast. Temperatures are re-checked every week so communities return to a full forecast as soon as they warm up. Store locations are sourced from Just Bite Me’s retailer database.
