Hi.
Wondering if anyone can help my friend with a problem she's having with the attic.
Thousands and i mean thousands of common house flies, are in, and dying in the attic. Why they are coming in and how they are are coming in we don't know but you can hoover them up and within a week or so its covered again in them.
The house is out in the country and is about 10 years since it was built. Its a bungalow and there isn't another house within a 500metre radius.
Any ideas whats causing it? And how to prevent it.

Probably this; http://en.wikipedia.org/wiki/Cluster_fly

Quite common in the country, we have the same issue in our house. Aparently they favour the same house year after year. We use 'bug bombs' and fly spray in the loft in the summer to try and kill them off but not sure how effective it really is.

I worked at a place that had an annual influx of Dasyhora caynella. Messy to say the least, some chap would come out and nuke them and there would be a carpet of the little bleeders all over the place.
There are quite a few different flies which do this. Terminate themmmm!

We get these in our static caravan. Get between the walls and in the roof cavity - hateful things.

I don't know if it's still on the go but Vetchem spray really sorts the bds.
It's for dog fleas.
One application per year for my sash and case windows. No more overwintering flies.
Haven't done it now for about 5 years. Still virtually nothing.

Thanks lads.
It's not a seasonal thing, it's year round strangely enough, and the attic is panelled so if something was getting in there and stting we'd see it. I think.

Have you checked to make sure there is not a dead body in the attic ?

she needs to set a "smoke bomb" off up there.

The flies hibernate and as mentioned by another poster , they will keep returning .

Set the smoke bomb off now and the problem will at least be reduced , we get them twice a year , coinciding with when the adjacent fields are ploughed .

There must be something that eats flies.

Chamaeleons? A tank of John Dorys?

Yep, take the top off your header tank and keep John Dorys in it nuts

They are cluster flies.... Take my advice dont waste money with smoke bombs... have it treated by a professional pest fumigator.

They are like herpies once you have them you will always have them. A proper treatment will reduce the risk of them being active to maybe once a year.

What ^^^^^^ said!!!

Cluster flies will usually appear in autumn ready for hibernation and emerge again in spring! They lay their eggs by worm mounds in the spring and the return the following autumn. The adult flies would have pheromone marked your house so they will return again and again!

The best course of action is to have your loft ULV SPrayed every spring and autumn to knock down the breeding population.

Pm me and if your in my area I can give you a quote or I know pest controllers over most of the country.

Depends on size of loft etc but usually £60-£90 per treatment.

But PHers do get discount!

HTH?

Almost certainly cluster flies. We get them in the loft and last year I bought Swak Pack (just Google that for suppliers). You get about 3 aerosol cans and a dispenser for £50. I set it up in the loft and after about 3 weeks they'd all gone.

Didn't bother this year as the aerosol leaves a slight residue (if you have stuff stored in the loft it's worth covering it) and it seems to have deterred them, however, there are definitely some up there so I'll probably have to buy some more.

Thought about the body myself!!
Thanks lads. Will tell her to get rentokill or someone in. Thanks for the offers of numbers but we are in ireland so doubt they cover that area!
