Hello everyone!
I am completely new to this site and completely uneducated on reptiles and snakes, so forgive me if I ask a lot of questions.
My girlfriend and I just brought home a little baby red-sided garter a couple of weeks ago. He's about 6 inches long, eats like a piggy, and is full of life. We lovingly call him Oliver Twist.
I am just mildly concerned because a week ago I found a mite crawling on him which I was able to pick off. But now he appears to have 2-3 small bumps on his skin closer to his tail. I have since been treating him with Nature's Chemistry reptile spray. Are these just mites under his scales, or could this be a bigger problem?
I was worried he could be impacted, but I have him on aspen bedding, and he eats in a seperate cage, so I dont think that's the issue.

Please let me know what you guys think. Thanks,
-Collin.
