RE: THREE CREATURES IN MY BATHROOM

Very nice compilation of photos @borjan. These small flies of the Psychodidae family I would say that they are the most common insects in bathrooms, their larvae can always be seen by the drains or cracks that there are both on the floor and on the walls of the shower, in these places they find all the food they need for their development, as you mention in your post. Greetings my friend.
