Yes, problem is that the applicators are not following the protocol.  They
say that it takes too long to drill all the holes and do small injections,
so they just drill one big hole and blast in an excessive amount of
pesticide.  May well be a problem to beekeepers.  Suggest that you contact
your county agents.
