I've been keeping bees here for about 2.5 years. I have requeened twice with mixed success.
I have had mite problems but FGMO seems to be working well this year. The biggest problems I have are ants. It is a constant battle. If you do not patrol your bee yard and an area roughly 100 feet around it weekly, you will be in for a nasty surprise. It seems to take about 2-3 days for a successful hive to be wiped out by ants.
I use a home-made vented top board for circulation, and I use pallets for shade (top and sides)
Thank you,<br /><br />Gregory
