Summo, the reason I asked is imo there's no longer any need to have big entrances for ventilation with OMF so the entrance can be reduced to 7mm - adequate for the bees but too small for a mouse....so no need for a mouse guard.
The problem with MGs is they scrape pollen off the bees as they go through.
