Bees in Kauai

We recently spent a relaxing week on Kauai at a lovely home with some friends.  One evening, just as I got out of the shower, I was called urgently into the study.   There were about 100 bees crawling around on one of the windows.  We looked for  the way they got in, but found none.  We also saw bees flying around outside.  Figuring there was a swarm nearby, I went out to try to locate it.  There were many bees flying around the eave above the window, but palm fronds prohibited me from getting a clear view.  Then I noticed a 4-inch diameter hole in the siding below the window (where a cable had been brought in) and a few bees were flying in and out.  We notified Mike, the caretaker and he called Oliver, a local beekeeper who promised to come out the next day.
Meanwhile I discovered a small opening behind a soffit from which a bee would periodically emerge.  We covered the hole with packing tape.  Overnight, the bees in the room died.
When Oliver came out the next day, he found bees flying into the dryer vent and into another opening on the opposite side of the house.  There were more bees in the study (now called the bee room) as well as a couple in the bathroom and in the downstairs room.  Oliver set up a bait box, but no one went into it.  He also showed us from where he had removed a colony from the walls of the house last year.  The next day, thousands of bees suddenly appeared and settled just above the bathroom skylight and crawled into a gap in the flashing.

In this photo, most of the bees had already entered the wall.  Note the lizard looking at a potential meal.  There were geckos and lizards all over, as always in the tropics, and they were feasting on the bees.  One lizard was on the wrong side of the glass (not this one) and kept snapping futilely at the bees.
Oliver came back, removed the siding and...no bees.  They had crawled into the gap below the joists.  He had to drill several holes in the wall of the bee room and spray in his homemade bee repellent (that smelled heavily of almond) to drive the bees out to the roof where he patiently scooped them up and put into a nuc box.  Finally he caught the queen in a special cage.  Now all he had to do was wait for all the girls to go to their queen in the nuc and then take the nuc away.
We swept up the dead bees and now could go barefoot again.
