This is why we put NO pesticides, or grass enhancers, or any other chemical on our yard. The bees (sort of owned a few streets over) loved our hyssop last year. Bought some honey from the neighbor and could actually taste the hyssop. Nothing like local honey! Hope they get this problem solved.
I have five large hives in my backyard. Louisiana is nearly the bug capital of the world, challenged only by the number of weeds.
We do apply pesticides, but only in the evening after the bees have gone to the hive. I use fire ant crystals on beds that are within 2-3 feet of the hives because ants are prone to invading hives. I also keep the grass and weeds around the hives at bay using RoundUp.
As long as the pesticides are 'contact killers' and don't have residual action, it is safe to use them with care.
