Contrary to popular belief, wasps arenโt all that aggressive, though they can get a little more feisty as the season goes on. The reasons they sting arenโt too complex – theyโre doing it to protect their nests, their colonies and themselves. Hornets, on the other hand, are much more likely to come after you so if you notice them swarming around your home, youโll definitely want to contact the experts at Abra Kadabra ASAP.
