While you might not like hot and muggy weather, mosquitos love it. As D.C.’s weather grows more humid over time, the city becomes a more hospitable place for the pests for nearly a month longer.

A new report from Climate Central, first flagged by Capital Weather Gang, finds that since 1980, the District’s mosquito season has grown by 29 days.

The leap from 114 days to 143 days makes D.C. the U.S. city with the 11th largest increase. Nearby Baltimore, Md. topped the list by providing mosquitos with more comfortable conditions for a staggering 37 more days than it did in 1980. The numbers are based on ideal conditions for Asian Tiger Mosquitos: relative humidity greater than 42 percent and a temperature between 50 and 95 degrees.

This is more than just aggravating. Considering the spread of mosquito-borne illnesses like the Zika virus, it constitutes a public health risk.

As of yesterday, D.C. has had 14 total human cases of Zika, according to the D.C. Department of Health. All of them are related to international travel, rather than acquired locally by a mosquito bite. However, in an alarming first, the Florida Department of Health announced today that is has likely found the first documented cases of local transmission on the U.S. mainland.

D.C. DOH has been holding citywide “Fight the Bite” events to give residents free Zika prevention kits stocked with insect repellant, mosquito dunks, condoms, and information sheets.
