Cluster Flies;

https://en.wikipedia.org/wiki/Cluster_fly

(Apparently they don't represent a health risk)

My employer, forced by financial pressure, has had to shut down half of the office block I work in in order to save on heating costs (It's a large building that's poorly insulated) - Consequently we've been shipped over to one half where the upper floors have previously been under utilised due to a problem with the aforementioned flies.

The office we've been crammed into an office is the top floor - 5 desks for 8 people, expected to work from home etc.

Last night, at dusk, in an office that's around 4 x 6m, I estimate that there was around 40 flies crawling on each window, of which there are 5 in total equalling around 200 of the buggers.

Which is not pleasant. At all.

Because there are also bats roosting in the roof space above the office (it's not unknown to find them in the office the next morning) options to deal with the flies are very limited.

We have the electrical zappers which are not useable during the day for 2 reasons;

The stink of burnt hair / flesh
They spit out bits of the fly up to 1.5m from source

So they're left on over night which isn't that effective. And we need to clear the mess up the next day.

Is there any legislation that dictates working conditions that would cover this?

And is anyone aware of an effective solution to deal with the pest?

TIA.

We had them in a loft once. I took the vacuum cleaner up there and waved the hose around for a bit. It wasn't too hard to catch them as they seemed fairly lazy and gathered around the lights. I'm led to believe that they don't lay eggs inside, so once they are gone you shouldn't have more popping up.

Just make sure you use the garage vac if doing this at home, not the good one..

Little buggers use pheromones, don't be surprised if they come back. They lay eggs outdoors, come indoors to hibernate and use the pheromones to mark favored places.

We had our first visit of them last month, appeared out of the extractor fan in bathroom one afternoon. Visit into the loft revealed lots, combination of hoover and normal fly spray over a 72hr period cleared them.

Apparently they can't use sprays on them because they'll harm the bats, which are protected by law...

the vacuum suggestion seems pretty decent.. might be worthwhile picking up a 2nd hand one from Gumtree or the like, using it and then throwing it away.

As a point of principal, I don't see why I should spend my own money on an issue my employer should be resolving.

However, I have pointed out that machine mart sells a suitable Hoover to £32... Of course this would raise the question of who empties the thing once its full...

Encourage the bats to come into the office at night. They will eat the flies. Problem solved.

We get 'em for a brief period every autumn in an upstairs room. They seem to lay eggs in the shutlines of a velux. Open the window = carpet looking like a currant sponge mix.

They're annoying, but they're really no more than that.

An electric UV zapper shouldn't spit bits over a range - they use 'em in every single food prep outlet in the developed world, ffs.

And, no, unless you happen to work in a food prep environment, there's no legislation that means you can skive off early because of a few flies.

The problem is a little more expansive than that;





And I'm not looking for legislation that allows me to "skive" I've got enough to do, thanks, I'm looking for legislation to lever a more proactive response to the problem so that I don't feel like showing with domestos when I get home...

Do you happen to have a black cat by any chance? hehe

OP, that looks bloody awful and yeah, I'd be looking for something to be done about that if I was expected to work there!

Bog standard fly spray should decimate the little s. Will not affect the bats upstairs, needs a direct hit on the flies FFS!

Look up cluster fly on eBay, buy a few smoke bombs, set them off over night and ventilate in the morning. Repeat regularly until solved.

I had them in one of my rental properties I bought some pesticide/aerosol bombs in the loft never been an issue since, a big open space I'd imagine would need a professional fumigation team to sort it.

For clarity, I have no intention of doing anything, this is the sole responsibility of my Employer and they appear to not be doing anything.

Smoke bombs and pesticides are not an option as they may harm the bats...

I feel for you, they stink and aren't nice to have around. We've just had our loft fumigated frown

Anonymous call to environmental health, call the RSPCA and tell them about the bats/people trying to get rid of them.

It might stir up some trouble if that's what you are after.
