Hello everyone! In my tortoises enclosure, I have started to notice some tiny bugs. They are some sort of fly I believe, they have tiny wings and are black. I believe this is because of me constantly spraying his bedding down and trying to keep the humidity up. However, I was worried as to if these bugs could cause any harm. If anyone has any experience on this I would be grateful. I have also attached a picture where you can see the substrate, maybe I am keeping it too wet? Thank you in advance
