Am a bit confused - you say the beetles can't change direction on a 90 degree angle, yet they seem to " change direction on a 90 degree angle" from the bottom board to the hive sides. Please explain.
That's brilliant! You seem to have covered everything. And the user report from 2:30 shows the outcome, not just the promise. Best of luck with this product!
Just installed on my 10 wide hive. Within minutes I watched 3 beetles climb around the front piece of angle and into the hive. This is a little discouraging, I will see what gets collected on the bottom board. Hopefully, in a few weeks I will be pleasantly surprised. Doubtful on first installation.
