Take action
See standing water? Report it.
Catch basins, clogged drains, and neglected lots that hold water are mosquito factories — and the city can act on them. Send a report and we'll get it to DC Health.
In DC, our standing-water form files the complaint with DC Health on your behalf (and keeps the committee in the loop) — add the location and a line about what you saw, and submit. For water on your own property, see the Treat page instead.
