The oak tree in this picture is a Heritage Oak in Menlo Park that has been around for more than 100 years. As is common with these old oaks, cavities develop and swarms of bees move in. These guys were a little too close for comfort so we initiated a trap out. In this case however, the trap out turned into an all at once vacuum rescue. The bees had all left the colony in a panic and collected on the outside of the tree where they drew out some comb and were waiting for a pick up.
