In the past 11 days I managed to find 6 of these bugs at my flat. From what I noticed, it can climb on the walls, is highly resistant to pressure – I can’t crush it if it’s in my fist. I saw them both at day and night.
I asked my mother and she hadn’t seen anything like this before. Could you help me?
This is a blood-sucking Louse Fly. They generally feed off the blood of livestock, especially sheep, and there are species that feed off the blood of deer. Do you live in an area where there are either livestock or woodlands with deer? Some species feed off the blood of birds and there are frequently pigeons and other host species found near homes. Perhaps there are nesting birds in your immediate vicinity. If their preferred host is not available, they are opportunistic, and they will also feed off the blood of other large animals, including pets and humans.
I live in bedroom districts and there aren’t any deers or other animals as we are still further from the forests. There are some swallow nests in the holes of the roof, maybe it could be the cause? We have been living in this flat for over 12 years and we have never seen any bugs like this.
I’m pretty scared now, as I have two cats. Is there any way to terminate Louse flies?
The bird nests seem like the likely source. Though we do not provide extermination advice, there is not much chance that the Louse Flies will proliferate much with these BugGuide reproductive statistics: “Females rear one offspring at a time, the larva feeding in utero from special ‘milk’ glands. The mature larva is ‘born alive’ and immediately pupates in the soil (or on the host in some cases). Most are host specific on bird species, with a few occurring on mammals.”
Good news. Anyways, thank your help. It is really amazing that there are some nice people who are willing to help in identifying some unknown animals like in my case, Louse fly, which both me nor my family have not seen all their life before. I am happy to know that they are not dangerous to people and can not proliferate much.
