There are so many uncontrollable variables when it comes to bears including the individual personalities of the animals. With this setup, they will not get a taste of the honey/larva combination before I am alerted--and I will have some extra noise-making element to the system. I might even reinforce it with used re-bar. It is also in a fenced in area--not that this will stop a bear, but it will also provide some extra noise. I've had a lot of
experience dealing with "city" bears which tend to be harder to intimidate. Most bears that aren't too used to humans run with nothing more than a quick yell. But I did have to use bear mace on one in the middle of the day when we had all the neighbors out and about and one simply wouldn't spook even with rocks being thrown at it--and wow does bear mace work well--but this is not the location where I will be housing the bees.
I am just in the process of relocating to my homestead where I will be putting the bees. It is a tiny-house set up on about 3-acres and is about as quiet as can bee (ha ha, lame-ass joke). In the summers I will be sleeping with the windows open, and probably on the porch a lot as I like to sleep outside. I've had bears around a couple times so far, but it is rare. One day I was working and accidentally almost stepped on one as I turned around a rocky bend and he scurried up a tree. He didn't come down all day while I worked on my projects. But he already had 2 tags on his ear, which means one more garbage infraction and the DOW would put him down, he is likely dead unfortunately.
No system is perfect, but I think this will give the bees a pretty good chance. There is also the possibility that bears will never be an issue, another person in my
PDC has a large bee setup in bear country without any protection and never had a problem. Too many factors to control them all, but I think I'm playing decent odds.
