Bobil,
Every time you take the hive apart to inspect the frames, you are giving the SHBs 2 days of free roaming in the hive, laying their eggs everywhere. The bees are so busy fixing everything that you changed that they ignore the SHBs. I see this every time I have to work in my observation hive. It isn?t until the third day that they lock the SHBs back up and remove the eggs and larvae. Opening the top in not a problem. It seems to bee the brood nest area that causes the most problems.
If you put 2 frames too close together the bees will have to cut through them and restore bee space. I once added a honey frame that was too wide and it ended up against the glass on when I closed up the observation hive. We watched them cutting wax and move the honey for several days. When they were done, it looked like the comb was cut with a laser.
