>How would I be able to protect a hive from any spraying?
First, make sure they know you have bees. Usually they will be willing to not spray where you are. Second make sure they spray after dark. If they don't, inform them it's a violation of the label (and therefore the law) to spray for mosquitoes in the daytime. If they don't adjust, report them to the EPA. If that doesn't help, you're SOL.
As long as they spray after dark it won't make a very big impact.
