A little concerned

I checked the hive tonight and saw a few things that I really didnt like. I think its time to call John and ask him to stop by. The first unsettling thing I saw were about a dozen dead bees on my top screen. Not sure why they died. In addition to the dead bees, I saw a moth, two coach roaches and a few small bugs in the hive. If all these extra insects were not enough to unsettle the new beekeeper, the sheer number of bees appeared to be low. I will call John tommrow and ask if he can stop by in the next few days.
