Aaagghhh! The dreaded city sanitation department has been out tonight - I saw them "fogging" mosquitoes. Fortunately they were some way away, but who knows when the truck will drive down our street! I'm worried that the insecticide will "do for" my bees! A few are outside tonight, but thankfully it is a cool evening and it is probably fewer than normal.
I will have to inspect in front of the hive for corpses tomorrow.
