WOW! That was an awesome post but also proves what I said in my last one: BEE KEEPING IS HARD!!!!
BTW....I've seen photos of hive beetles and I've most definitely seen some in my hive last year. I am planning to get those little trays that hang between frames filled with veggie oil to catch them (if you think thats a good idea). HOWEVER....when I opened my hive the other day I saw a different kind of beetle. They looked like a brown roach- so much that I think that is likely what they were. However, I only saw like 3-4 of them in the whole hive.
I didn't treat for Mites last year so you may well be right. I somewhat understand them and how to look for them and treat them thanks to some great literature that @Chikn sent me last year and which I really need to re-read.
I was just about to order one or two new bee packages, but if there is much chance that those I saw flying in and out and around that day are likely to move back in, I'd sure like to save my $150 (w/postage). Heck...that is 6 FRUIT TREES!!!! ha. I also have a better chance than most people of catching a swarm on someone elses property, because almost every year someone calls our Fire Dept to report a "Huge ball of bees" and they know to call me immediately if it happens this year so I can try to capture and move them into one of my 2 hives.
Anyway, thank-you so much for taking so much time to provide me so much detailed help. I really need it. It seems like the more time I spend reading about bees online, the more I realize how little I know and the more lost I become. This thread has been a Godsend thanks to you, @Auburn , @Chikn , @Derby42 and a few others. Thanks again.....A LOT!!! I feel like I've finally got a fair grip on most things fruit tree related, but I'm just completely lost on bees.
