Lady that I bought lemonades from her gals from on hot southern California Independence Day & gave her & gals the oddity of honey comb, called bout bee problem weeks ago Friday. This was bout week & half after Thanksgiving. Husband told me painters had come week before Thanksgiving.
Came over & showed me their guest house w/ dead bees inside stairwell & bee poop having stained the inside of the interior. I took a drill & opened up the exterior spot the bees previous entrance/exit, painters had spackled over. Some bees started coming out to see the new yellow exterior paint job, but not in great numbers. I looked in vain but had seen no other exits/ entrances.
I asked if the owners if they pesticided the bees & they said no. The bees most likely found a secondary exit after week(s) stuck in their hive. Bees liking their home clean held it in for that time & then en masse finally released their loads. I'm still nagged that the tenants musta been freaked by having a second floor full of bees & sprayed em. Or can bees die en masse by having toxic poisoning due to having not eliminated that long?
Holidays have these owners busy so am going back after new year to see what can be done.
Here is the video of the bees coming out of drilled hole:Bees Sealed in Guest House by Painters
