We have ridiculous numbers of flies in our kitchen. We kill them by
the hundred with the fly swat (they are quite easy to kill) but their
numbers don't seem to be reducing. We have an electronic zapper baited
with a bit of ham fat. We have fly killer window stickers. We have a
home made bottle trap with inverted top to make a funnel, baited with
pieces of chicken in it. Their numbers just keep increasing. We keep
all doors and windows shut as much as possible.
I've had a look outside to see if there are any dead animals about but
there aren't and there don't seem to be many flies out there!
The traps don't seem effective. Is there a better bait to use?
Any other ideas would be appreciated.
May seem like a daft question, but do you live in the town or country? We
live in the country, with a corn field just over the back fence, and we
were plagued with flies and insects for about three or four weeks before
they took the corn off. Within a few days of the farm workers harvesting,
the number of flies dropped quite dramatically.
You also mentioned dead animals. Have you noticed any unpleasant smells
about the place recently? Do you have cats? They have a habit of bringing
in livestock that can creep under fridges, etc and then die.
We also invested in a 'Boots' plug-in fly killer, that comes with a bottle
of insecticide that lasts for quite a few days.
There was a TV news item about plagues of flies being caused by farmers
spreading slurry in th erecent heatwave. A pub had lost virtually all of its
One of the pleasures of living in/near the countryside I guess.
This is probably it. They spread a load of sh*t all over the field
behind us (ex rapeseed crop) on the hottest day of the year (Sunday
10th Aug). What is the breeding cycle of these things? About 10 days?
The only odd thing is that they only enter the kitchen, no other rooms
in the house despite having no windows or doors open. Could they get
in via the aga's flue? (It's switched off)
Obviously the kitchen has food in it but there are no nasty smells
that I can detect. We try to keep it clean as possible, put rubbish
By the way they are what I would call 'ordinary flies', ie: not as big
as a blue bottle or a horsefly but not the tiny ones either. They do
die with flyspray. They don't seem wildly attracted to fresh fruit or
meat (we have no rotten stuff). Some of them are a little smaller -
maybe juvenile versions of the larger ones.
We bought some flypaper yesterday, this has been the most effective

What sort of flies? There are many species all with different habbits
and food requirements. If possible post a picture on a website
somewhere and give a good indication of size and a description of
their flying habits, noise etc. Pop the URL into the group.
A UV (blue light) thing doesn't need any bait the light attracts the
flies. But not all...
You've only used bits of dead animal. Lots of flies prefer fruit.
There must be a food source in or near the kitchen. Rotten bit of
fruit behind the fridge, back of the vegitable cupboard? Rotting spuds
are really liked by some flies but the pong would probably have
alerted you first...

I had a similiar experience in a rented house. We had lived in it for a
year when blue bottles started appearing by the dozen.
1st u could try and determine if they are coming from inside or outside the
house. Close all the windows and doors, kill all flies then wait and see if
In my case we finally pulled out the fridge and found a "nest" stuck between
the back of the fridge and the wall, about 2 ft off the ground. The fridge
was under a fitted worktop so nothing could have slipped down the back, we
still don't know where it came from. It was 'orrible, gave me the heebee
Similar experience when on holiday in rented farm cottage. Flies
suddenly crawled out the woodwork in the early evening. Only seemed to
be in one room (mine). Tens and tens of them, maybe up to a hundred.
Fly killer didn't kill them (I *think* they were the black houseflies
you get - like bluebottle sized but not blue), even trapping some in a
jam jar and squirting neat killer on them just dazed them, they were
flushed down the loo, and were still alive and floating on the top when
it finished flushing...
Never did find out where they were coming from, but sounds like similar
woudl have been possible. Shut all the windows and kept the door shut
all day - loadsaflies. Kept them open - loadsaflies. Thick swarms of
them everywhere in the room each evening.
Worst holiday of my life, I was a teenager and it's left me very jumpy
when flies buzz close (I was told to put up with it and go to sleep
regardless, since nothing could be done, and not allowed to sleep
anywhere else, to my horror).
I'd go with removing EVERYTHING from the room they're in. Everything
out of cupboards, move all the appliances, if you can, check behind
worktops etc, under floors. Flies tend to get drowsy in the dark, and
re-activate when a light it turned on. Takes a while, but you might
find that going in at night and shining torches into spaces behind
cupboards will start flies into coming out if there's a group of them
behind there (may take 5-10+ minutes).
On second thoughts, given black houseflies die with fly killer I have
here, maybe the ones in that holiday home weren't houseflies. They
looked like them, but it was years ago now (though the memory of that
room with the flies covering everything still is a clear if yesterday).
Holidays on a farm where they keep animals can be expected to suffer from
Even if they don't have animals they spray crap on th eland which attracts
Once had a French gite near to cowsheds. It was horrible. The flies were
much tougher and than normal ones too.
"The traps don't seem effective. Is there a better bait to use?"........
There's part of your problem, the 'bait' you are using is just attracting
more flies in, as is the UV light. Get rid of both and straight away there
will be a *slight* difference. Cleanliness is most important, ok not saying
your'e fodder for 'life of grime' but how often do you empty the kitchen bin
(and wash it afterwards)? Also do you leave any dog/cat food out in bowls?
My advice is to get rid of any potential foodstuffs and smells and stick
with the flypaper, you can also spray residual crawling insect killer on
surfaces where the flies alight, although this will only kill those entering
the room not prevent them from doing so. If it's really, really bad then you
should consider flyscreens for the doors and windows. I could go into great
detail about correct placement of UV flykillers along with the selection of
the correct tube wavelength for each species of fly but I suspect that would
bore most people senseless.

One of ours is spreading onto pasture. The grass ain't growing now
anyway, so won't unduly suffer from being spread on. And when it does
rain he can no longer get a muck spreader onto that field without
seriously damaging the ground.
Seems to me the above was "a little bit of knowledge".
