Default Damm Roaches

Thanks for helping straighten out my memory :^)

Phosgene COC12 also called Carbonyl Chloride. First came into use during
World War 1. Where it was used alone or mixed with Chlorine. Inhalation of
the gas causes sever lung injury. With the full effect appearing several
hours after exposure. Carbon Monoxide and Chlorine in the presence of a
catalyst produces Phosgene. Phosgene reacts with water to form Carbon
Dioxide and Hydrochloric Acid. Phosgene COC12 also called Carbonyl
Chloride. a colorless, chemically reactive, highly toxic gas. Having an
odor like that of musty hay.

I thought that mixing ammonia and chlorine produced Phosgene gas..as you
say..exceedingly deadly.

Here is one of my best tricks at getting rid of roaches on a boat. Make
sure that you can open all the windows and hatches from outside the

boat.
You do not want to go inside the boat to open the hatches. Put a 5

gallon
container inside the boat with a few fans to circulate the air. Pour

equal
parts of Clorox and Ammonia into the five gallon container. Now run like
hell and get away from the boat. Clorox and Ammonia mixed together

produces
a vary deadly substance called Chlorine Gas. Chlorine gas is odorless

and
colorless, and highly deadly. Chlorine Gas will kill everything and

anything
in a matter of a minutes. Many a house wife has died from mixing the

two
chemicals together by accident.

I MUST REPEAT CLOROX AND AMMONIA MIXED IN EVEN SMALL AMOUNTS WILL KILL

YOU
VARY QUICKLY.

The generator trick works well and the smell will be gone after airing

out
the boat.

Because they are cold-blooded organisms, insects do not survive very

well
in
extreme cold or hot temperatures. Each insect species has certain
temperature and humidity conditions where it thrives. Although there

are
some differences between species, it should come as no surprise that

our
domestic cockroaches are best adapted to temperatures that we maintain

in
our homes. They do not develop or reproduce when temperatures are too

cold
(below 45degrees F) or too hot (above 115degrees F).

Hot and cold temperatures can be very effective in killing

cockroaches,
but
the adverse temperatures must be maintained for a period of time. Hot

and
cold treatments are also most effective when they "shock" the

cockroaches'
system. If cold temperatures are gradually lowered, insects have
physiological mechanisms that allow them to survive the cold. But, if

you
take a jar of cockroaches from room temperature and put it into a

sub-zero
freezer, the insects will be dead within a half hour. They just cannot
adapt
that quickly.

Because cockroaches cannot survive temperatures above 115degrees F to
120degrees F, it is possible to use heat to eradicate cockroaches from
restaurants and food service establishments. After all heat sensitive
equipment is removed from the building, the temperature is increased

to
about 140-150degrees F for five to six hours. It may not be possible

for
the
homeowner to increase the heat that much inside the home. But if a

small,
infested appliance has many small crevices and can withstand

150degrees F
heat, a similar procedure can be used. The procedure is simple --

place
the
heat-proof metal appliance in an oven, and after several hours at
150degrees
F, the roaches will be dead.

Cold can also be used to kill cockroaches, but it takes a prolonged
exposure
to low temperatures to kill egg cases. Appliances or furniture can be

left
in a garage when temperatures are below 0degrees F for several days.

If
moving, leaving possessions in a truck or van will do the same thing.
Infestations in wall voids or indoor cavities can be subjected to

extreme
cold by using a CO2 (carbon dioxide) gas canister. This will freeze a
localized area. Infested appliances can also be fumigated with CO2.

Place
it
in a plastic bag or other airtight container and inject carbon dioxide
gas.
Allow freezing to occur. If a small item can be subjected to freezing,

it
also can be placed in a freezer for several hours (or overnight) to

kill
the
cockroaches.

Errr....why not just go buy a chunk of dryice, toss it in and
close
the
boat up?

One extra Oxygen molecule.

But it's not available is it? I thought it would be bound up and
unusable.
We spray it on a fire to choke it out so I figured it may have

oxygen
but
it's not available. For that matter, water has oxygen too doesn't

it?
But
you can't breathe it since it's not available.

I may be wrong ... I'm just wondering.

Carbon dioxide (from dry ice) is a simple asphyxiant. If it

displaces
the oxygen in the air it will kill you, but it takes quite a bit of
it. You can be exposed to 30,000 ppm for 15 minutes and still be

OK.

Carbon monoxide at 1500 ppm may lead to death, and the 15 minute
exposure limit is 35 ppm for an hour. This is because without the
extra oxygen molecule, CO has a 200 to 300 times great affinity for
hemoglobin than oxygen does. So even if there is enough oxygen
present, the CO will kick it off the hemoglobin and you will die.

So
it isn't just a simple asphyxiant any more.


Roselie is correct about the CO being more than an asphyxiant. But

the
object
of all this is to kill roaches, right? It's been awhile since

college
zoology,
but I don't think roaches even have circulatory systems, let alone
hemoglobin.

I have frozen roaches in liquid nitrogen (when bored during a late

night
in the
lab) only to have them thaw out and crawl away. Hardy little

beasts.
Does
anyone even know whether depriving them of oxygen (with CO, CO2, N2,
whatever)
will kill them? I bet it's damn hard to do.
