Homeowners are divided when it comes to hornets. Some say they’re aggressive, but some experts believe they’re peaceful insects that only retaliate when they need to. But why do hornets attack in the first place? Here are the most logical reasons that explain why.
You provoked them
Hornets are actually one of the most peaceful stinging insects out there. It sounds ironic, but it’s true. They’re passive when no harm comes to them, so they don’t become aggressive for no reason.

However, if you accidentally pin them down or try to swat them, you’ll force them to retaliate. These insects can sting multiple times and cause swelling, discomfort and allergies that can lead to life threatening complications.
You approached their nest
Like most social insects, hornets are the most aggressive when they feel like you’re threatening their home.
These bugs defend their colony fiercely. Just being near their nest is enough of a threat for them, causing them to storm out with a frenzy.
According to Ehrlich Pest Control, you need to maintain a radius of more than 3 meters from the nest to prevent these bugs from attacking you.
They’re raiding a beehive
This one is not about attacking humans. It’s about attacking what we humans raise.
Raising bees is not only great for keeping fruits and flowering plants healthy and blooming. It’s also incredibly convenient to produce your own organic honey as a healthier substitute to sugar.
However, hornets have a reputation of attacking beehives and stealing their honey and pupae. They often raid the waxy caverns of a beehive when food is scarce. And they can attack multiple hives too.
It happens after a hornet scout discovers a beehive and marks it with a pheromone. It then leaves and comes back with more hornets to invade the hive, kill all the bees, eat all the honey and steal all the pupae to feed them to their grubs.
This raid not only costs bee lives. It also costs us humans money, time and all that effort into raising those bees.
To see how it happens, here’s a video from National Geographic that hornets can attack beehives.
Bonus Tips: How do you deal with attacking hornets?
Now that you know why hornets attack. Here are our take on some popular solutions that claim to stop hornets from charging at you.
- Swatting does not work. Unless you’re using a Tennis Racket Zapper that can stop hornets immediately, we don’t recommend swatting them. As we have mentioned earlier, it does not work. Not only will you miss them since they’re very agile fliers. The possibility of being stung is too high.
- Waiting it out doesn’t get rid of them. Hornets come and go, depending on the season. However, they definitely don’t just die out on their own. Waiting for a nest to die during winter doesn’t work because not all the hornets die from the cold. Their queens have adapted to hibernate and start a new colony during spring.
- Cucumbers may not work. A lot of websites offer cucumbers as a solution to repel hornets. Interestingly, there’s not enough research to prove this. All we have that get us going is this study from Oxford that only tells us why some insects won’t lay eggs on surfaces with cucurbitacins on them ( the chemical found in cucumber that’s said to repel bugs)
So why do hornets attack? Outside forces cause these bugs to attack. It’s the most common link between all the reasons that we mentioned. Just remember to keep yourself out of the strike zone. Contact the right people to treat these insects, and don’t keep bees in your backyard. If you do all this, you’re in the clear.
