Honey bees in building
Multnomah County Oregon
Hi, if it is honey bees and they are building a nest, you will need someone willing to do what is called a cut-out. If they have just arrived, then it is considered a swarm. If it is a colony of yellowjackets, then a professional exterminator will do the job.
The Portland Urban Beekeepers Association and the Portland Metro Beekeepers Association should have beekeepers that will be willing to come out to retrieve honey bees. I suggest that you look at their websites then contact them for assistance.
