Vespa Crabro Germana Invasion!

For those of you that are not up on your latin or familiar with all the insect species out there, the vespa crabro germana is also known as the European hornet, or in central Virginia, also known as the Bell hornet.  Either way, they are scary looking creatures.

Now I'm not one to go looking for a fight, particularly against a creature that has the capability to fight back, but there are several reasons that these buggers have got to go!

First off, they are big.  No, they are huge!  These are the 747 of the wasp/bee/hornet world.  These monsters will get your attention when they go buzzing by you or fly up to you to see if you have something that interests them.  You can hear the noise from their wings buzzing as they come torpedoing down on you.

Secondly, they are a predator to the honey bees.  They can wreak havoc on a hive.  Luckily, most of my hives are pretty strong right now and should be able to defend themselves from the hornets. More than once I have been working my hives and one or two of those hornets have come buzzing in to see if there was any opportunity for the taking.  I tend to start flailing my arms around in the air in an attempt to "shoo" them away.  Of course, the shooing action doesn't happen if my hands are holding a hive frame full of bees, because then there are a lot of unhappy honey bees right in my face!

Thirdly, they are building a nest in the soffit of my house.  This isn't a major problem, except that they are attracted to light.  At night, if we have the porch light on, we can't even open the door to let the dog in or out.  They hang around the windows at night and cause chaos when going in or out of the house.  This attribute also gives us a potential method of extermination.

A simple 5-gallon bucket 3/4-full of water with a bit of dish soap to break the water tension and a light suspended above the bucket pointing into the water.  The hornets fly to the light, bounce down and hit the water and get stuck and die.  Surprisingly, my light lasted all night and was still on in the morning.  And there was a good amount of hornets floating in the bucket.

This seemed to be a good solution, but from looking at the soffit where the hive is located, and all the hornets still coming and going, the process would have to be repeated for weeks to make any dent in the hive population, which probably has an active queen keeping the population strong.

I'm going to have to call in reinforcements to get this job done.  Tomorrow an exterminator will be called to "remove" the hive and hopefully kill all these hornets.  It will give peace to not only my family around our own house, but also to my honey bees.  If I'm lucky, the exterminator will come while I am home and can get some pictures.  If you are about to call me a wimp, and wonder why I won't go spray them myself, did I mention that the soffit is about 30 feet up in the air?  Stay posted to see how this turns out.  You won't find me climbing a ladder to fight with these beasts!


  1. Oooohhhh!! We have those too and you are right - they are HUGE!!! I am glad you called the professionals...don't want to mess with them inside your walls. Luckily, ours tend to stay in the 8 acres of woods we have and only send out their "scouts" to bug us.

  2. We had a wicked nest in our soffit by our front door this year that just wouldn't go away.. I set up a drywall vacuum setup (pipe that goes into a bucket of water (and a few drops of motor oil) to trap dust (or hornets) and vacuum hose is at the top to to vacuum) them out 4x.. diminished their numbers, but didn't deter them.

    What finally worked 110% was powdered Sevin pesticide. Put a bunch in a turkey baster and generously dusted the opening by the brick moulding at night. I didn't see one hornet by morning.

    I didn't expect it to work so fast !! I am waiting til it is cooler to rip soffit apart to see and clean out this nest and seal it back up better to thwart future nest attempts
