It is like having little pockets of secret rooms that only the beetles can access.
If beetles can access their secret rooms before the bees, they are safe.
It is like a cat and mouse game.
The bees will always lose with the old equipment.
The options on the market (oil traps, gizmos, chemicals) will only win a small battle but the beetles will always win the war. They are treating the symptom and not the cause.
In my course I walk through in detail how I ELIMINATED these secret hotel rooms and evicted the beetles.
