The whole hornets area is an awkward jumble of crazy pathing combined with loads of wanderers.
Do a pet attack and Fluffy will often do a round trip of the zone, pulling mobs is not much better either as they often take the scenic route too.
Celebrate any time you get a single pull.
On the plus side, golems and goos don't assist the buzzies and they are eligible for the summoned line of nukes.

Spawns in the southwest area of the zone near all the wasps, its ph is the two "an immolator hornet" near the entrance to the valley. They float pretty high up too like the old posky imps.
