Apparently they have hatched !!!

I just dustbusted the daughters bedroom window sills and opened the windows so they couldn't build up again today and WOW the swarm that was in the crevasses around the windows.

Doors and windows now all open.

Is there any way to break the cycle? I know they lay their eggs in earthworms, but have also been told they hibernate in the ceiling cavities????
We have more here than we did last year, and it is slowly getting worse each year.

Any thoughts?

Pest-Advice?

Last night I was working in the study foolishly with the window open. When I had finished the ceiling was black with the little monsters. I sprayed and sprayed and sprayed and then shut the door and left - this morning I vacuumed up the corpses by the dozens. The windows have been shut in here today and there are more of them already on the inside of the window frames - yuk yuk yuk yuk.

They are a type of beetle, that looks like a fly. And they all hatch at the same time and come into your house to die.[}:)]

Hi, we got them bad last year and I sprayed the house with Fendona (from Farmlands) you just need to be a little careful as it is a white solution and depending on the colour of your paint as to whether it leaves a residue. It has kept the spiders off the house for 12 months, plus it has kept the flies at bay and is just starting to run out so I will be out again to sort them. Cheers.

That's interesting, I'm sure I saw something that Ruud Kleinpaste wrote that said they are a beetle.[:I]

Ugh, they make me itchy just looking at them.... The image on that website really inspires me to get a can of spray and 'get them!!!!'

The goat shelter roof can get pretty thick with flies at night but they don't cluster like that, so I don't know if they are actually cluster flies... they're bloody annoying though. If I disturb them they tend to zzzzz in a loop and try and resettle somewhere, usually my head or if I'm reaching up, my hands.... they drive me nuts!!!

I rest my head on Athenas side when I'm milking her, it's like a big hug, a really nice relaxing way to milk her, she's so good and doesn't move at all so I can shut my eyes and carry on milking without worrying about any hooves near the bucket..... until a low flying fly starts to buzz my ears and goes in for a bit of landing practice. They are really dopey and just seem insistent on landing in the same place no matter how many times you shoo it away.

I'm always a bit reluctant to use anything toxic in the goat shelter. The goats like to rub up against the wooden sides of the shelter for a scratch and I'd hate to use anything that would be dangerous. The floor in there is just the bare ground (covered in post peelings) so any washing the stuff off would just go into the ground, plus the whole thing is wooden apart from the roof so I don't really want to get it too wet.

I just pray the silly sods are clinging to the roof when a good hard frost hits.. all of a sudden, like.

I've been hearing heaps of people say there are more flies this summer.
Blardy things!!! We've had a few crane flies as well... I know they don't do any harm but they do tend to fall apart and in the thick of crane fly season I seem to be constantly wiping their body parts off the bench. Legs mostly.

The house we have just moved into had been vacant for a few months and we have a swarm. I have rung the pest man and he is coming tomorrow to spray them inside and out. They are an inch deep on the windowsills in the garage[xx(]

Only problem I have with that is I have insulfluff in my ceiling cavity and I can't sweep of vacuum the dead flies up without taking out heaps of my insulation :(

Is there any way of diluting the pheromone?

Hi Xartep,

The flies continue to release odour for a few days, so if they have been there for more than a week they are not likely to be a problem. Especially if you have sprayed the areas where the clusters had formed.

I am not sure about your chances of 'diluting the pheremone', you could try a odour neutralization spray or gel. One of the type that contain a chemical that binds with the odour molecules not a perfume that masks the odour.

A few weeks ago I went around the outside and sprayed that Raid outdoor surface spray all around the closed window frames, its worked well so far, we do have them because I noticed loads on the barn the other day, but none bothering me in the house. yay!!!!

Just had a look at your article Pest advice - When should the lawn prills be used? we are surrounded by farmland, is there any point in using it just around the house area? does it also kill the worms that the eggs are in? thanks.

Hi Beltie,

The Lawngard Prills should be used in spring/summer when the fly larvae hatch from eggs and go in search of earthworms which they parasitise. So this is the prevenative measure.

Hi Organix,

Thanks for the heads up on the Radio NZ discussion of cluster flies and black field crickets. If anyone wants to know how to deal with black field crickets let me know.

Cheers
