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.

The mosquito counts

The part we can’t show you yet.

Everything above measures effort. None of it measures mosquitoes. That’s what this fall’s research is for. Local university researchers sampled adult mosquitoes across Capitol Hill in September, comparing blocks with high and low Itty Bitty participation, and they’re sampling catch basins for larvae next. Whatever the counts say, they go right here. If they say we’re wrong about something, we’ll publish that too.
