Hello! My rat Blizzard also got some type of lice/mites on her a little more than a month ago, she was often itching, had scabs and became more nervous and timid. I treated her with Ivermectin for three weeks, fully cleaned out the cage and gave another half dose the fourth week (to be certain all the bugs were dying). Now she is back to her normal self, and has only a few scabs which didn't heal yet. I never really saw the bugs, I assume they come out at night, sorry I can't help you identify the ones on the tape.
Hope this is will be helpful in case you decide to treat your rats with ivermectin!
