Coverage
Block Captains, by ward.
These are only the blocks someone has already claimed in Washington, DC. There are thousands more, and most of them aren’t on this chart yet.
Coming this fall
The part we can’t show you yet.
Everything above measures effort. None of it measures mosquitoes. That changes at the end of August, when researchers start counting what the traps actually catch at a first round of sites, with a wider neighbor-run phase to follow this fall — so by the end of the season there’s a real set of numbers instead of a feeling.
We’re still working out with researchers what a fair comparison looks like. Whatever the counts say, they go right here. If they say we’re wrong about something, we’ll publish that too.
