Okay, its a 'hard pass' story, but i bet a lot of people have had something similar!
I got a message through a popular website that someone had a 'swarm' to relocate. Couple short messages back and forward and i got to the truth of it - its a hive that has been in the roof for almost 2 years, tin roof (so no easy access) and the *expert that came to price it up* said they would have to cut a hole through the ceiling and take them out through the house!
And this lady was asking for someone to come take them for free!
Now i am happy to help and happy to collect a swarm, but the $600-$700 she was quoted sounds about right. Re-plaster a ceiling and at least a days work. Imagine how big the hive could be in the ceiling space, and you would have to get all of it out or it would attract new bee's shortly after.
We are still in full lock-down or i would at least go have a look for her, but shy of ripping up sheets of tin, i don't see any easy way of removing a 'swarm that has been there for almost 2 years'!
