How to Kill Hornets

Without Pesticides

Hornets, and all other wasps, are useful in the garden in many ways.  They predate lots of other insects and larvae, taking them back to their papery nests.

How to Kill Hornets

But what if you're allergic to them?  They always buzz around your food when you dine alfresco, get underfoot when you're harvesting fruit, and generally act like they are the boss.

You can tell the workers from the queen, mostly because the workers are the smaller ones, and they make the most trouble.  If you know where the nest is, then you can avoid it, leaving them to do their work and they'll leave you in peace.

In the early spring, the first ones you'll see are huge!  These are the queens, who will go on to start the nest, hatch out her brood and produce the workers who are the problem children.  Kill these first ones, and you generally won't have an issue.

Later on in the heat of the summer, the workers are trying to keep food and water going to the nest to feed the young ones.  This is where the bait and kill type of traps work the best.

For those times when it's absolutely crucial to keep them under control, this method, The Sweet Death, as I call it, works.  Say you're having a picnic or a barbeque.  The most unwelcome guests will be those pesky hornets.  This is the method;

  • A few days ahead of time, take a large clear wine bottle, 2 liters works well.
  • Put about an inch or so of wine, beer or fruit juice in the bottle.
  • Add some sugar, if it's dry wine.
  • Around the mouth of the bottle, and inside the lip, smear some raspberry jam. 
  • Prepare to watch the hornets unable to resist going in.
  • Interesting fact; hornets can't fly upwards, so once they get into the bottle, they can't avoid being drowned in the wine or juice.  They have a sweet death, eating something they love.

Other ways to trap them consist of traps that either get them stuck on a sticky surface where they struggle and get even more trapped until they perish, or a quicker non-chemical method using a similar trap to my system, a jar with a lid and filled with some kind of bait or attractant.  These can catch wasps, flies and other pests too, depending on the bait. 

I tried two different ones to test them out. 

In addition, if you know where the nest happens to be, the occupants can be killed off with a spray bomb.

Here's some useful stuff from my affiliate;














I would avoid foggers and other chemical sprays, except for the bomb type for the nests.  After all, they may work to kill hornets, but they will harm everything else too - including you!


Five days later, we have a winner!  Hands down, the best trap is...

Rescue TSW-BB6 Visilure TrapStik for Wasps

Rescue TSW-BB6 Visilure TrapStik for Wasps is the one that I'll buy again.  This took five days to be almost covered with dying hornets, plus the odd other kind of pest.  Sadly, a tiny butterfly and a few little moths got trapped too.  However, the other trap, with the few inches of beer in it caught mostly moths.

Wasp and Hornet Killing Tips

  • Put the cage as seen here on the ground, if you have a lot of wasps foraging in the grass or close to the soil level.
  • Use a bird cage to protect butterflies and other non-pests from getting to it.
  • Get two or more if you have several areas where you see lots of wasps - most likely there are more than one nest, and they won't forage in each others territory.
