REGINA — After weeks of a surge in Regina’s mosquito population, numbers are now declining across the city.
Ashley Thompson, the City of Regina’s manager of parks technical services, said mosquito numbers have “gone down quite significantly.”
“The average per trap was 200 mosquitoes [weeks ago], and now we are looking at 25 mosquitoes per trap.”
Thompson said the weather has played a major role in the decline.
“There’s been very little, if any, rain in July. So, that has helped, as well as the hot weather that dries everything out,” Thompson said.
According to Canada Weather Stats, Regina received nearly 145 millimetres of rain in June, the highest monthly total recorded in the past 10 years.
Mosquitoes need standing water to breed, Thompson explained.
“They do need the water to breed in. So the standing water is more significant than, say, tall grasses,” she said.
The city’s mosquito control budget has also played a role in its approach to managing the population.
In 2026, the city allocated $1.2 million to pest control, but Thompson said funding for mosquito control was reduced.
“We used to treat buffers around the outskirts of the city. That budget was reduced, so we focused our efforts just on inside of city limits this year.”
Without regular treatments around Regina’s outskirts, Thompson said weather conditions can contribute to more mosquitoes making their way into the city.
“The wind can help kind of blow them into the city.”
Thompson said there are no discussion happening on re-tooling the control program.
“Our mosquito control population is quite strong. Population spikes like that can happen with rain; there's just not very much you can do.”
Thompson doesn’t anticipate the population will spike again this year.
“Numbers should remain quite low. We haven't had much rain. There isn't a ton of rain in the forecast.”
