Yeah, you hava varroa in both hives. I agree with MB though. The first thing you need to do, is not get too excited. Then you need to perform some type of test. Personally, if you have a screened bottom board, with a sticky board, monitor the mite fall. If not, do a sugar roll test. I describe it on my website, but will show pictures in the near future. If you get an unsatifactory number, then its decision time. If you have to use chemicals, do it. It is alot cheaper than having to start all over. I would reccomend that you get your bees on small cell foundation, use a screened bottom board if you are not, and decide how you are going to control them. Finsky is right, I would use one or two proven cures. If you take chances, you could lose it all by next year depending on the infestation. Its up to you, but don't ignore it, or you will lose it. And BTW, welcome to beekeeping!
