'[EE] SMART electronic mosquito repeller'

Hello guys.

Since I'm going to have my honeymoon in a place where mosquitos are
really dangerous (malaric fever & co.), I was wondering if any of you
has ever built a really working mosquito repeller. I went googling but I
am not satisfied with fixed frequency oscillators (btw, does anybody
REALLY know the frequency it has to tune to?) or harmonic oscillators I
found. I was wondering if a frequency modulated oscillator would do,
tuning every little beast at least once per second. Any idea? VCO? PIC &
PWM?

Many Thanks in advance.

Alessandro

One thing I read is that mosquitoes are attracted to the CO2 emitted from
your breathing; that is how they detect you.
Someone came up with a slow CO2 discharge to attract them.  I don't have any
real technical information, only that.

Alessandro, AFAIK no electronic repellent works. They're one of
those quack devices that have been around for years, based on
unsubstantiated science with enthusiastic, glowing testimonials (from
friends, family members and shareholders no doubt)

Mosquito buzzers' worth queried

http://news.bbc.co.uk/2/hi/health/4218234.stm

Scientists find natural mosquito repellent (interestingly uses the
same mosquito picture. I didn't know mosquitos had agents)

http://www.msnbc.msn.com/id/6847440/

http://en.wikipedia.org/wiki/Insect_repellent

"For protection against mosquitos, the U.S. Centers for Disease Control
recommend DEET, icaridin, or oil of lemon eucalyptus for skin, and
permethrin for clothing, gear, or bed nets. Oil of lemon eucalyptus was
found to be more effective than other plant-based treatments, and had
similar effectiveness to low concentrations of DEET. Some of these
repellents are not recommended for use on younger children. Safety and
effectiveness concerns have been raised regarding the use of citronella.
It should not be used on children"

In a recent program by The Bug Man (Ruud Kleinepaste) in The Amazon
had him slapping on industrial-strength DEET, but he still got eaten alive

A former list member, Alice Campbell, reported some success whilst
camping by having a burning candle to generate CO2 that lured the
mosquitos away to some extent. Not a practical solution though for
an Alessandro on the go

1.    Bathe in very dilute DDT solution :-)

2.    The combination of CO2, heat and moisture really does work as a
Mosquito attractor.

My long term experience is that if you have a very good mosquito
target then lesser targets tend to be ignored. When our family of 4
went camping and slept in the same tent my son was always the target
and others were relatively less attacked. I was least attacked. If my
son was absent my daughter and then my wife were next on the list. I
was the least approved target. If I am by myself mosquitoes will
attack me.

SO

If you have a good attraction source present you may be immune from
their attentions. So, a suitable CO2/warmth/water vapour source may do
the job. if you don't want this source to be you or you newly wed one
then you may wish to think about an artificial stand in :-)

FWIW DDT is *the* mosquito killer of choice, and can be used in very
low concentrations and absolute volumes for this purpose. However,
certain stupidities and bad science and worse thinking have removed it
from general availability for this purpose.

Being up to date on your relevant "shots" and scrupulous use of
mosquito nets is also a very good idea.

Beware the odour of feet. Mozzies *really* like foot odour and will
actively seek out the source of said emissions.
I don't know if its a diversion will work or if it will just pull more
into the area. But perhaps some sort of baited trap on the inside of
your tent/room? you can get UV based attractors with fans and the like
to catch them. If you seed that with a freshly used sock of a night time
you might see a benefit.

I don't know what the exact frequency is but I can tell you it's up
in the 19KHz range. I know this because it hurts my ears. My ears are
sensitive to the frequency and my friend has one in his attic (we were
working on the roof). I had severe head aches from that noise maker.
My friend forgot it was on (for a couple of years). Didn't make the
mosquitoes go away though.
