Actually, unlike bees, a hornet can sting you over and over. And the venom of THIS hornet is much more toxic than regular, so it IS something to be concerned about.
Do you live in BC or WA? If not, don’t worry about it. And even if you do: how often are you traipsing around hornet nests? Really? How many times have you been stung more than 10 times in rapid succession by hornet? Really? If your answer to those are: hardly ever, and never. Then NO you still don’t need to worry.
Less than 50 people a year get killed by these things, and they’re native to one of the most densely populated parts of the world. And it’s been here for over 6 months and you’re just now hearing about it. Really people, get over your panic addiction.
