health π¦ Pittsburgh's mosquito season is going way longer π¦
Mosquito season in Pittsburgh is extending longer due to summer storms and high humidity, according to Climate Central. This is happening in Pittsburgh, Pennsylvania, where the season is 22 days longer than in 1970. In 2025, the Ohio River Valley had 156 'mosquito disease days,' making up about 43% of the year. This extended warm period increases the chance of disease transmission from these pests. Local health officials are actively treating areas while urging residents to eliminate standing water sources.
