More and more people have been reporting sightings of this type of beetle in their Milton Keynes homes in the past few days - but what is it and are they dangerous?
The beetle in question is a 'Devil's Coach Horse Beetle', and its natural habitat is to live in and around decaying matter.
However, a number of people on a local Facebook group have reported finding them inside their homes across the city over the last few weeks, especially in the evening.
One person commented: "I had one of these beasts in my kitchen the other day! I screamed!", with another saying "it’s striding around my front room like it pays rent. Massive great big thing!"
The beetles are fast-moving, preferring to run along the ground rather than fly and are often mistaken for an earwig at first glance, but beware of getting too close.
The RSPB advises: "If you disturb a Devil’s coach horse, it adopts an aggressive, scorpion-like position - it raises its rear end and opens its powerful jaws."
"If it still feels threatened it squirts a foul-smelling fluid from its abdomen. Beware – this beetle can also give a painful bite."
