Is it possible to have compassion and also act against that compassion. I don't like killing wasps. It gives me no pleasure. It is great that you've had the experience of not being frequently stung by them. I also have compassion for mosquitos but I'm still going to wear inspect repellent that sometimes kills them and drive my car that causes them to splatter against my windshield.
The comparison doesn't hold. Mosquitos do actually seek out and parasitize humans, and often transmit infectious diseases of serious import. Neither is true of wasps - they don't even pose the same risk of incidental contamination that many flies do, nor do they offer humans violence without significant provocation. That humans rarely bother to take the trivial effort required to understand wasps well enough to avoid offering provocation, I grant, of course. But such disregard is no less culpable for being ordinary.
