Something dead in the house - flies!!!!

[Notcontent]

So I am pretty sure there is a dead decomposing creature in the house - either a mouse under the floorboards or a bird in the chimney... there is no smell but I started getting flies in one of the bedrooms! Over the last week I have killed at least 30 or more of the vile things...

This will stop I hope!???

Do you have wood windows?

I do! Why?

We've just had the exact same problem in our kitchen. Horrible fat black flies, I would get rid of loads come back 10 mins later and there were more! I'm guessing a dead mouse somewhere (like you no smell).We do have a demon mouse killing cat.

We had this a couple of years ago. We tracked it down to the fireplace where we had installed a recessed electric fire. Fed up of all of the horribly bloated flies we sealed the fire completely and that ended the problem . Thankfully there was no smell.

I had this in my living room so I sprayed fly killer stuff into the vent above my living room window and they all kicked the bucket and fell out. It was revolting. God knows what had died in there. There were 19 on my floor, it was utterly disgusting

We had this a couple of years ago and found a dead mouse under the sofa in the dining room! DS and I played rock, paper scissors to decide who had to get rid of it....

Glad it’s not just me!!!

I guess I will just wait for it to pass.... as I said to dd, it could be worse... rats, cockroaches, etc

when I had this it was an unwanted dinner of beef stew my child had tipped into the kitchen table drawer weeks before ... dh said he never saw anything like it and he spent a year doing autopsies.

Sounds like cluster flies, opened our loft once and omg. thousands of them buzzing around. Emptied a can of spray in there and shut it quick.

I do! Why?

When we had wood window frames, we often had flies ‘hibernate’ in there, then start to come out when the weather warmed.

Worth opening all the frames to check if they’ve made a home in there (be warned, if they have, a lot will fall out, although they’ll be dozy so won’t immediately fly off. Have a hoover on standby!

Is there a smell? I think it's a really distinctive smell when something is rotting 🤢
We had it a few days ago and tracked it down to a dead mouse under the piano.

Otherwise as a pop said it may be cluster flies. They are in my parents attic and no matter what they do they keep coming back

No flies but we had small, black, hard shelled bugs.
Turned out to be coming from a paper maché model that ds had made last year (with flour and water thanks to mil!). Model thrown out = no more bugs!

They hibernate in houses then appear about this time when the weather starts warming up.

We had them a couple of times, they stopped when we replaced our gutters and soffit boards

We once came back from a trip abroad to a room full of dead flies (at least 100) . A couple months later that same room had a moth infestation. And then little back beetle type things. Only that room 🤷‍♀️

I could write this! Our house seems to be infested at the minute and we can't locate the source anywhere.

I agree with earlier postings. They are almost certainly cluster flies which hatch about now.

Look in the loft, that is where they will have overwintered.

Better to find the empty maggot shells and flies than all the wriggly maggots

Interesting.... the room in question is at the top (Victorian terrrace house) and there is access to the loft space. So yes, they could be cluster flies....
