Summary: Have you ever been lying in bed in a small room, trying to go to sleep, and had house flies buzzing around keeping you awake? To me, there are few things more annoying than this. However, keeping you up at night is among the least dangerous things that house flies presents. There are some very cost effective fly control products that can deter flies in a 1,000 sq. ft. area. Check out the video and related products here.
Some people claim they would never hurt a fly. Too bad the fly does not feel the same way in return. Unlike horse flies and stable flies, common house flies do not bite. However, the house fly has some pretty disgusting habits that can create health problems for people. Luckily there are some excellent fly control products on the market today that can deter flies in a 1,000 sq. ft. area. Check out our video and related products here.
Did you know that flies can be carriers for infectious disease? Typhoid, cholera, salmonella, bacillary dysentery, tuberculosis, anthrax, and parasitic worms can all be transmitted from a fly to, say, your cheese sandwich. The next time a friend criticizes you for wildly waving your hands over your cheeseburger, perhaps muttering some kind of incantation, tell them that you are not warding off evil spirits, but you are warding off house flies. The long list of diseases spread by the common house fly will make them reconsider questioning your sanity.

House flies can be very hard to swat. They have a compound eye that can see in many directions at once, and a highly evolved evasion reaction that enables them to detect changes in air currents. This is the reason that flyswatters have holes in them to reduce air currents so flies don't realize that something is about to hit them until it is too late. Another way to confuse a fly is to swat at it from two different directions at one. Try clapping your hands together right above where a fly is resting. The fly moves so quickly upwards when it senses danger that you might crush the fly just when it thinks it is escaping to freedom.
Common house flies can reproduce at astounding speeds under the right conditions. Flies undergo a complete metamorphosis in which they change from an egg into a larvae (known as maggots) then into a pupae, and finally into an adult. The transition for a fly from an egg into an adult is made very quickly. Only a few hours are needed for a fly larva to hatch from an egg, about two more weeks to undergo all the changes to become reproductive adult. They only live for another fifteen to twenty five days, but the adult female can lay several thousand eggs over the next few weeks of her short lifetime.
Flies breed in manure. Horse manure is the preferred medium, but human, pig, cow, chicken, or other forms of manure will work just as well. Because flies have such a close connection with manure, they are synonymous with filth. Flies have hairs all over their legs that can carry particles of manure with them wherever they go, thus spreading germs to wherever they land. To make matters even more unseemly, the fly regurgitates part of its last meal onto the surface of wherever it lands, so a little bit of fly vomit will be on any food where the fly has landed.
Interestingly, it seems as if the fly itself is aware that it is dirty. Have you ever noticed that a fly frequently rubs its front legs together? It is actually cleaning its legs because there are taste and small receptors on them. The fly's legs also secrete a liquid that helps it walk on walls. The fly's body is so light that it can hang upside down from a ceiling just by the surface tension of the liquid secreted from its legs.
So, we have established that flies are gross, are germ carriers, and you don't want them around your food. You might be wondering, what is the best way to get rid of them? If you are solely concerned with keeping flies out of the house, you can use insect screens on doors and windows. Copper screens are better than painted steel screens because they do not rust. You can also reduce fly populations by using sticky flytraps, or bait traps.
The foods that attract flies have sugar or protein in them. A home remedy mixture of water or milk with brown sugar, over ripe bananas, or blackstrap molasses with an added pesticide will attract and kill flies. Insect sprays labeled for the purpose of killing flies are effective methods of pest control for killing individual flies. Avoid sprays containing poisons such as arsenic that can contaminate your home.
The very best way of getting rid of flies is to take away their breeding places. Garbage containers should be tightly closed. Compost piles should also be sealed off. Outdoor garbage should be transported to a dump, buried, or incinerated. Animal waste such as dog poo must be cleaned up. Septic tanks should not have any cracks or leaks that might attract flies. Basically, any organic waste or manure is a potential breeding ground for house flies and by removing the waste you will do a lot towards getting rid of the houseflies, that is, unless you want a personal experience with Love In the Time of Cholera.
There are also some very cost effective fly control products on the market today that can deter flies in a 1000 square foot area. Check out this short video and related products here.

Recently my kitchen was invaded with maggots. About 5 months ago my kitchen
sinks started overlowing everywhere, my apartment complex "fixed" the
problem for the time being. However, a piece of rotting wet wood remained
under my sink... Little pieces of wood would flake everywhere constantly.
When I saw the maggots that was my first guess. My apartment complex said
too bad but did replace the wood. BUT didn't remove the wet soggy wood.
Just put a new piece over it. Now I have flies everywhere they keep
appearing. Is the wood where they are coming from?? Thanks!

The moisture caused things to decay and the decaying matter is what these
maggots breed in. Remove the moisture and you will resolve your problem.

Google "bottle trap for flies" and you'll see how they are made out of
plastic pop bottles. You put something at attracts the flies in the bottom
of the bottle, but you don't add any water, which is usually put in the
bottle to drown the flies.

yesterday I found 40+ flies in my mudroom area. all around the skylight and

and then today, I have had 20 or so more! How can I find out where they are
coming from? Windows are closed

House flies are attacted to moist, decaying matter, as are many flies. You
need to discover where they are breeding and eliminate the source. There is
no magic to the fix. It's a matter of careful inspection and cleaning.

I have read everywhere that Mint deters house flies....so we planted mint
all along the side of our house at the back. I went to water the mint the
other day and at least 100 house flies if not more came out of the mint.
The mint I have has a purple flower like stalk at the top of each plant. I
have watched the flies from the window and they are putting their little
probe in each one and drinking the nectar! So much for mint warding off
house flies. It does smell wonderful though.:)

All of a sudden we have flies attacking our screens in the kitchenand
getting into the house. We always make sure that the counters, frig and
other places are clean. Also, the screens are secure and have no holes.
What would make them come to just the kitchen area?
Ask the Exterminator

Flies breed in decaying matter. With hot, humid weather, the grass in your
yard could be decaying to the point that it will support fly breeding. They
are drawn to the kitchen from cooking odors. Then again, you may need to
clean garbage cans kept outside your kitchen door. Put cans on bricks to
allow air to circulate under them.

We had water in our basement for the first time in 15 years. We dried it
out immediately (actually took 3 days) now we have flies all over. I kill
10 and 10 more appear. What can I do to rid my house of these filthy
beasts?
Ask the Exterminator
18 Aug 2011, 09:52
It's fly season. A damp basement certainly could be a fly breeding spot,
but it may not be the reason you suddenly have flies. Check the bottoms of
garbage cans and any other location that is moist. Flies can breed in any
decaying matter.

Hi, i recentley had maggots in my house, i know disgusting, were have a
very clean house. They were near my front door and once i cleared them,
they were still coming through the carpet. I had to get rid of carpet as
was mortified and with two young children i couldnt have that. Although
ive had no more of them ive now been invaded with flies, again these are
very slow and am able to get to them, but with no windows or doors open
they justb appear. My bins are down the other end of driveway. Please
help as im starting to pull out my hair.

There is no magic solution to fly control. Flies breed in moist, decaying
matter. That could be residue at the bottom of your trash bin, under the
bin, or it could be a spot of grease on the side of your stove. It could be
piles of dead leaves or grass. You need to search for the breeding spots
and eliminate them. Don't forget to check for dead animals in attic or
crawl spaces.

BOTTOM LINE-BAIT AWAY FROM PROPERTY!!!My amount of daily invaders was in
the 100's! We bought an OLD home, no maintence done, holes everywhere, farm
land, etc. MY MISTAKE, putting ANY strips, attractants, traps etc where I
SAW the flies! Window sills, by doors, they were everywhere and loved the
bait and died instantly, but more swarmed so more stuff used! They just
came and came - well DUH! I got smart, and got it all OUT of the house,
cleaned all dead bodies, strips, etc OUT! plasticed bad windows....went
around the perimeter of my property, traps and quickbait sprinkled,all
around the edge of the yard lots of quckbait and traps!THEN poof! Now only
get a few when the sun shines. The traps overflow with sticnky dead bodies,
have to get news ones as maggots even get laid in the traps....This all now
is AWAY from the house though!!!Now have new windows, new siding to come,
sealed everything, told neighbors to try to control manure cleanup (they
used my solution for the invasion probs as well, they were putting stuff in
and outside the house too) and the trouble is controlled enough to try to
live normal in this home. The basement still lets bigger slower flies up,
but we are fixing flooring....I almost lost my mind and said sell sell
sell!!!! GLAD IM STAYING, now know what to do come next summer! Foaming the
whole house so hibernating flies hopefully unable to get in...now what to
do about the BATS???

Hi exterminator.
I have a problem, and it's becoming a big one fast. For the last few days,
every morning I wake up, there is a huge amount, about 20 or more flies
just in the kitchen, not flying around. Just Idlely sitting on the walls,
and windows.They are not little either, they look to be matured/normal
size.I kill them all with bug spray then sweep them up. But why and how
does this keep happening?? Help asap please!!
Btw I live in Australia, and the current climate is wet but warm/humid.
Does this have something to do with it too? But how do they get in the
house!
Ask the Exterminator

You need to find the source. Killing the adult flies will not resolve your
problem. Look for areas where moisture is present. They lay their eggs in
moist, decaying matter. Tiny accumulations, not puddles of water. It could
be a glob of grease or a grape that rolled under the stove. You need to
touch things to be sure surfaces are totally clean. Examine the
refrigerator door and rubber seal for food residue. Check the rubber
stopper in the sink. Be creative in your search.

Something died in my basement. I smell it but can't find it.I think its a
rat from my neighbor next door. I have a number of flies in the basement
working their way up. Huge black flies. My Kids are terrified of them and
this is all driving me crazy. Is there some type of bomb I can use? They
are spreading like crazy. What about bleach or ammonia to kill off or
disinfect my house? Just. A week noticed.
Ask the Exterminator
05 Jan 2012, 10:59
A bomb will only kill insects exposed to the pesticide. The aerosol mist
rises into the air and falls straight back down. Not very effective at
killing insects inside walls, and that's where your flies are breeding.
They are probably Face flies, which feed on dead animals. Bleach kills
bacteria. It's not an insecticide. Eventually the flies will consume the
rat. The only other way to fix the problem would be to start opening walls.

I live in the tropics in the mountaneous area. The house is new
construction. It may seem strange what I am going to say, but swear its
true. Everyone is complaining about the flies in the home and how to get
rid of them. I am curious that the flies that get inside my home are
hanging on to dear life on the inside of my screens to get out and if they
dont get out on time they die.
I thought it was a coincidence but its been an ongoing thing.
what external factor could be killing them? I would like to know.
As I said earlier its a new home and I am careful as to not leave anything
lying around.
Ask the Exterminator
20 Jan 2012, 16:57
It all depends on the species of fly. If these are newly "hatched" flies,
they'll need a food source to survive. They are attracted to the outside
light so they fly to the screen doors. When they cannot get outside, they
die.
