Hello. I have recently had a massive infestation of tiny black bugs and some baby ones being clear, They are mainly around my balcony door which since having our newborn in the flat has been more condensed than usual however they have not been seen on or around my windows. My balcony door is double glazed and some how they are still getting through. I cleaned them off with bleach and water today as there were so many and it worries me with children in my flat that they could be of danger? They crawl very slowly do mot fly or jump. I hope you can identify them for me? Many thanks
