I live in a Victorian property in a town so am fairly used to insects indoors. We get bluebottles every time you open a window or back door for any period of time but in the last week we have acquired horrible dark brown/almost black flies that are about half an inch long, they are thinish rather than fat and round and have bodies that are in sections similar to an ant. I don't know if there is a connection but we have also just acquired ants in the kitchen (previously only ever had them in the vestibule area, not my personal vestibule obviously ).
Any idea what they are? and What is attracting them?
I won't be around for a while as I am cleaning like a mad woman but would love to read your responses later.
