Tell them the price of a package of bees..
Those bees are delivered to your post office for you to pick up. You KNOW they should be decent bees coming from the package producer.
With a cut out, you may find they are infested with mites or have other diseases. They may be meaner than a wet cat.. Adding them to your Apiary your still going to have those drones mating with your virgin queens until you can re queen that hive.
To pick up a package you dont have to drive far, you dont have to work, removing walls and replacing walls / siding / etc..
I consider the bees in a cut out worth about $50.00 If I can drive 4 miles to get there, remove a soffit, cut them out, replace the soffit and drive away.. I "MIGHT" do it for free.
Anything that goes above and beyond the $50.00 mark I have to charge for. I tell them my price, they get upset because I am getting free bees. I go home..
A week later I get a call to come do the job after they get a few more "quotes" from the pest removal companies.
I ask right up front if they have sprayed the hive, and explain to them the consequences if I cut open the first comb and it reeks of raid or pesticide.
If they deny spraying even then, and I find it HAS been sprayed. I load up and leave. Usually they own up and I charge that extra $50.00..
If the queen wasn't killed by the spray she may well be sterile. Everything you use to cut that hive out will be contaminated. It will have to be scrubbed scrupulously before you can use it again. Depending on how long ago they did it, the honey the bees abandoned may be fermenting.. It can be a REAL mess to deal with. Definitely not worth it unless your price is met.
