Why am I suddenly finding dead flies?

[Janesput]

I'm not aware of being bothered by live flies but I am picking up lots of dead ones, maybe 6/8 per day. Not enough to be called an infestation or cause concern that there's something dead somewhere, but I am a bit worried something is making my house so toxic flies can't survive!

The good answer would be it's the cold weather 🤣

Oh no, is it that bad?!

Are they bluebottle type flies OP? This happened to us the first Summer of being in our new house.
After researching it I found there is a certain type of fly that lays eggs around window pane seals and when the weather warms up they hatch.
We only had the in the bathroom and we were going crazy thinking they were coming out of the sink so we were leaving plugs in the bath and sink overnight.
We since had a new window unit in at the bathroom and it never happened since.

They are called cluster flies. Nasty things.

Dead bird down your chimney?

Do you have a cat? If there’s a dead body, the cat is likely to show a lot of interest in tbe vicinity.

Probably a dead mouse. We had one, I think it was under the floorboards.

Are they quite large? We had cluster flies once, big dopey things which were thankfully easy to get rid of

We had a pigeon die in the back gutter and it caused this. It was in January when it was dark and miserable so we weren’t out in the back garden to immediately notice.

It was horrible.

Dead mouse

Have you seen your neighbours recently? 👀

But why are the flies dying?

Because there nothing for them to eat

We had this last year over about 2/3 days..they seemed to come in on a bag of logs for the fire! They would appear one but one, fly about then would find them dead within hours
