My neighbour appears to have sprayed a colony of honey bees today. My understanding is that the hive entrances need to be blocked to prevent spread of the chemicals to other hives. If the entrance is blocked, would the bees not be contained? We have a lot of bees dropping and writhing around. My husband saw a cloud of bees fly up then them begin to drop. I was wondering if this is normal and if not, is there anything that can be done retrospectively to stop contamination? Or is it likely it was a swarm instead o a nest? Also, if it is dangerous to other animals who may eat the bees?
I am a bit reluctant to start making definitive statements here because it’s not really clear what is going on with your neighbour. Are you keeping bees yourself or just concerned about his? Is he a beekeeper or just treating a colony that has taken up residence in his property? Are the bees you saw come out and drop to the ground yours or his? Do you know what he “treated” them with? By the fact you are asking on here, rather than your neighbour is there some existing friction or issues between you?
