I started a thread regarding pierco frames and SHB. The comments started to move towards factors to consider when seeing SHB.
Here's my question from that thread:

I think it's also important to understand how beekeepers deal with SHB when they find it. Is keeping hives with minimal area for the beetle to hide from the bees a determining factor? I would think that has something to do with it but perhaps the strength of the hive is as important.

What is your first defense when seeing SHB? Or, at what point do you react to the signs of SHB?

Thanks for your comments
