Sorry to hear about your hive! How awful! Glad they're okay now, though.
Some additional thoughts on the fence: I use an electric fence with a solar charger because my apiary is in my cow field. If your beeyard is anywhere that grass or weeds grow rampant, then you are taking on another set of maintenance chores that you may or may not have time for. Some hot boxes throw out enough of a charge to burn the grass or weeds as they come into contact with the wire, but during moister times of the year, it can still overwhelm a fence. It's hard to mow around and if you like tidy beeyards, you end up weedwacking, too. Just a thought.
Having said that, if maintenance isn't an issue, then the fence works great 'cause raccoons are so tactile! We use hot wire around our chicken coop to keep the raccoons out and so far so good.
Live traps are awesome, maybe a neighbor has one you could try before investing in one? And, I love the tiedown idea (you've already got the heavy bricks to tie to). If the hive goes over again, you know it's something bigger.
