Hello, I am after some advice on removing a bee hive from inside a wall cavity without cutting the internal gyprock (or in the States I believe you call it a 'dry wall') wall or poisoning the hive. About three weeks ago, a swarm of bees took up residence in the outside wall of my house. They got inside the cavity through a small gap between the metal window frame and the brick wall. I am kind of annoyed that when this house was built in the 80's, the window fitters didn't spend 10 minuites with a caulking gun filling the gaps between the brick and metal window frames. I am extremely adverse to the killing of bees and we can't afford to rip the internal dry wall down, remove the hive and rebuild the wall so I decided to just accept it and let them live in the wall. Well I was happy with my solution but my wife wasn't. "They will eventually eat away the brick and destroy the plaster wall" she said, and then she went and booked an Exterminator who is coming in a weeks time. He is using a air compressor that sprays a fine talcum like powder that is deadly to bees but otherwise 'enviromentally friendly'. Aparently it is over for the hive in ten minutes flat and the powder permeates through the entire hive. I am not happy about this but my wife insists. I am after any advice on how to expell the hive from cavity permenantly with a chemical repellant, or some other method without killing them. (Or even if I can minimise killed bees by getting most of them out before the exterminator comes etc) Any advice would be greatly appreciated.
