Can you tell me what this is please? I had one in my bathroom which I flushed down plug hole then just found this one 2 days later crawling up door frame on the landing. It looks like it has wings but I didn’t see it fly, it was crawling both times. Not sure if it’s the same one which survived plug hole or of its another?? Don’t even know if it’s a fly but it only has 6 legs

Dear Sandra,
Please confirm that your location is Darlington, South Carolina.  We needed to do a web search to determine the location of the city Darlington, but we cannot say for certain that there is no city by that name in England.  This is a blood sucking Louse Fly.  They have warm blooded hosts.  Some feed on the blood of livestock, some on the blood of deer and some on the blood of birds.  They are opportunistic and they will feed off of human blood if there is no animal host available.

Hi thanks for your reply. I am in Darlington County Durham, U.K.  Is it likely that I will have more in my house?

Thanks for the clarification Sandra.  If this is a species that preys on livestock and you are near livestock, you may get more.  If it is a species that preys upon deer and you are near a woods with deer, you may get more.  If this is a species that preys upon birds and you have a bird nest in your eaves, you may get more.
