I've never had a roach problem on a boat before, but have got one now. Those
damm little German cockroaches have gotten a foothold, and nothing I'm using
is doing much good. I have used those Raid Max smoke type foggers twice,
sprayed everywhere with Raid Max, and then used the "wet" foggers. I can
knock them down for awhile, but not out.

Raid Max used to be the best, lasted for months. They've reformulated it to
a water-based formulation that smells completely differently from the old
style, and it doesn't seem to do anything unless you spray it right on them,
despite their claims that it "kills for up to 6 months".

Any ideas?

While I also swear by boric acid, I've heard that another treatment is
confectioner's sugar, and baking soda. The roaches, blest with both
an acid stomach, and an exoskeleton, cannot belch. It tears me up
just thinking about it.

....but I'll stick with the boric acid.

Boric acid powder.

I second that. Great stuff. You can use foggers, etc to keep them at
bay while the boric acid does it's thing, but all in all, the boric
acid powder is THE way to get rid of them permanently. Look for brand
names such as Roach Pruf, etc., put the stuff behind, under over
anything and everything.

Geez, I knew that at one time and I had forgotten all about it. Must be that
blue crayon in my brain.

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.

This stuff works better than anything I have ever seen. 4 parts Boric
Acid powder, 2 parts flour and 1 part cocoa powder (like Hersey's) and
spread it liberally around the boat, under cabinets and things. I know
this is ridiculous to say but don't let it get wet. It will make a
mess. I know one person who used this in their apartment and it cleaned
out the entire building. It takes a few weeks to work though.

Judging by all the good information you all have given I think its a matter
of finding out what the life cycle is and the egg laying cycle the hatching
period is 4 to 5 weeks someone said, the real point is here once you have
killed off the adults how long before new hatch start laying
so it is a repeat killing process at least four times as I SEE IT., miss one
and get reinfested.

I've hooked a small pipe to a CO2 tank, and probed small containers of
grain. Screw the top back on, and see no weevil, hear no weevil, and
best yet, eat no weevil.

Small concentration are lethal to many, many critters.

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.

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.

Wait until Keith Richards dies, and find out what killed him. That
will be your answer.

ROFL!!!

Check out Bayer (the aspirin people) Advanced Pest Control for ants and
roaches. I saw this stuff work when the pros failed. There is also a gel
called MaxForce that would work great on a boat.
You can get that at most exterminating supply houses.

Tuck in, Granny.

I went through a period where we were tired of throwing out the roach
infected food...so we ate with our eyes closed. No thanks....
