I have what I think is a hornets' nest on the soffit of my house (I'm not sure exactly what kind of bee or insect it is).
The nest has been removed since the photo was taken, however, the hornets keep rebuilding. They seem to build a new portion of nest about the size of a soda can each day. I remove the nest each day, but they are undeterred, and continue to rebuild.
Also, they have started to swarm the sewer vent pipe on the roof (not shown in photo). This is quite concerning; I don't want these things in my house. The pipe is about 2ft to the left of the nest, on the roof of the dormer.
Most people I've talked to recommend spraying the nest with hornet-specific insecticide. I can do this, but it's occurred to me that there isn't really much to spray.
How can I get rid of the hornets?
