I have been fight this issue for two years now. The bees are in Bend on the third floor of the building and I have been in contact with the property management company each time. Even though I use methods that I have used many times, the bees are extremely persistent. The property managers want to close up the entrance so the bees will be no more. After my second unsuccessful attempt, the property managers brought in a different beekeeper last year and they thought the bees were gone but I just received an email say that they are still there. Because of the height and building construction, they bees can not be removed. They will provide a manlift to get access to the the location (about 30' above ground). They have asked me to see if anyone else want to help me with closing up the hive. Give me a call 541-571-8462 Colton Kenshol
