Apparently this gable vent wasn't installed correctly as there is a horde of wasps that has moved in. My plan had been to douse them with waspicide, remove the vent, and then seal the hole, but I'd rather not be standing there for a long time figuring out the "remove the vent" step.
Online, it seems like a lot of these are installed with nails from the outside, but there aren't any visible, so it's got to be something more clever. Does it just snap on and off? Do I have to climb inside my attic and unscrew something from the inside?

FWIW, it is a typical install for vinyl siding.
This could be installed in 2 different ways. Either way the vent or portion of the vent is installed before the siding goes on.
First way, a base plate or ring that will hold the grille/vent is nailed in place first. It defines the shape of the vent, and provides the means to hold the finished part that shows in place. This allows for easy cutting and installing the siding with the proper expansion gaps around the base of the vent.
The second way, it goes on as a one piece unit, with a nail flange just like the first one, that gets hidden by the siding, but this one will need to have the siding place into the groove around the perimeter, making it a bit more difficult to install.
