G'day Gerald, Wilma & I have eaten a lot of bee grubs, however we're not your (me that is) average Westerner. Wilma reluctantly went along with it. It's easy, just put an empty frame in the brood box so the bees make mostly drones, then take it out at the desired time. To harvest the grubs, simply put the comb in water hot enough to melt the wax, then strain the grubs out. What I did then is pour boiling water over them while they are still in the strainer to get rid of any residue wax. They kept good in the fridge for a week. They also froze well.
It's a great way to get a good supply of high quality protein without any carbon footprint. The good part is, it's free.
Good luck with that Gerald, cheers:)
