Re: Bee Hive dilemma!
If I were you I'd pass on this property. If the asking price does not include remediation of the bees and hive, then you're on the hook for it yourself. If you can't afford the repairs and the price of the house/market value leaves no room, why take on the headache?
Removal of the bees shouldn't be that big of a cost, the reason being is that the person capturing the bees is getting an active colony worth easily $500 - $1000. I'm willing to bet you could find a local bee keeper to come remove the bees for free or a fraction of what you've been quoted.
If you do not deal with the house, the bees will continue to return. I do not believe that you need inhibitors, insecticides, and all the other crap you're being quoted, but you do need to get the wall opened up and cleaned out. Once that is done, it is necessary to seal the exterior so that the bees cannot return.
If you've got lath an plaster interiors, then it's a good bet that your insulation and electrical in that wall is more than lacking. I personally would strip the interior side of the wall, clean it out, upgrade what is needed, then install drywall. It will be a bit messier than doing the work from the outside, but IMHO, it will be easier to repair the interior than the exterior to have a seamless repair that looks like it never happened.
