Just moved into a brand new ground floor flat (in south west London) and keep coming across a number of bugs. So far I think I have come across 3 different types. There have been some in the kitchen, but most recently they have been seen in the bathroom and hallway. My bathroom does not have a window so does get a bit steamy but the flat has an air flow system to control the air flow and reduce condensation. They can be quite hard to spot against the flooring and tiles but once I spot one there are usually others.
Any advice would be much appreciated as I'd really like to know how to get rid of them / if they will cause any harm/damage.
