I saw it and my first reaction was 'wtf this isn't a syntax error?' Took me a while to figure out what to google to find what it's called.

An apartment complex that has a bed bug infestation will have a very specific smell. It's almost a boxy but sweet sort of smell with maybe a shoe-polish finish? Kind of like a stink bug, but less intense and almost a little fruity. If you've ever been on the L in Chicago early in the morning, excluding a holiday weekend, before people have infested it with their own grossness, that's the smell of bed bugs.
