>>Have taken out many in past, but in doing so used a pickax and sledge hammer to get to bees....along with cement cutting blade in circular saw taking time.

How many hours would a job like this take?

>>But they do go up and down the insides of the blocks...

Did you find thay can only fit two parallel combs in the small cavities?  What was the largest span nest you ever retrieved from cinder blocks (I imagine a nest in such small cavities could extend many feet)?
