Public health officials in Manitoba are urging residents to take precautions against tick and mosquito bites as warmer temperatures and recent rainfall have increased insect activity across the province. Manitoba Health, Seniors and Long-Term Care issued a reminder on June 28, 2026, about the risks of Lyme disease from black-legged ticks and West Nile virus from mosquitoes.
The province advises using insect repellents containing DEET or icaridin, wearing long-sleeved shirts and pants when outdoors, and checking for ticks after spending time in wooded or grassy areas. The risk of Lyme disease is highest in southern Manitoba, where black-legged ticks are established.
For mosquitoes, officials recommend removing standing water around homes to reduce breeding sites. As of late June 2026, no human cases of West Nile virus have been reported in Manitoba this season, but surveillance continues.
