Wasp

Much sleeker and sharper (literally) than a honeybee, wasps are a terror for children, pets, and anyone foolish enough to try to remove their nests without the proper tools or protection. Their sting is quite painful, and when their nest is threatened, they can attack in a swarm in defense.

Naturally, the location they choose to create their nests is in dark confined spaces where they can raise their eggs in safety out of sight. Hosing their nests down with a water hose may seem like an effective strategy, but it does not get rid of the eggs that are still inside the nest. And this is to say nothing of the vengeful wasps that are experts at identifying threats.
