Damm Roaches
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? |

I probably shouldn't let anyone in on the secret because there are SC
boaters reading this, but I'm a nice guy...... If you go out into the COUNTRY, where there are country stores with lots of old stock laying around in their hardware departments, you can STILL find bottles and granules of Dursban, the banned, but great-working insecticide the pest control industry has gotten their friends in Washington's EPA to wrestle away from the consumers who quit paying pest controllers to spray into the cabinets. If you get the granules, load up the dry parts of the bilges, behind cabinets/refridgerators/stoves with granules. Dursban STILL does a first-rate job, like it always did, killing off the creepy crawlers. The other source I found out about is that the EPA, in cooperation with powerful golfers who contribute to campaigns and don't like to be bitten by ants on the 1st tee, have quietly gotten golf courses exempt from the pest control bribing. It's called Dursban Pro, now, and if you know someone in the golf course biz you can get your supply from there. My house and its parrot pets, who are very sensitive to anything that will kill a roach, have been saturated with Dursban since its introduction. None of us...human or birds....has chemical weapons lesions leaking puss from its use, here. Just don't pour it on the kids or spray it where the kids can play in it. Dursban only needs perimeter spraying, anyways. You need to see the South Carolina State Bird, the "Water Bug". It's a roach-like, 4 inch long, dark brown beast of a beetle that's actually quite harmless, once you get used to him, that can cause heart seizures in the unenlightnened, when he crawls across your face in the dark at 4AM after a drinking binge has fogged your memory. Unlike the German roaches, they'd just as soon fly as crawl, being very comfortable with either mode. Stomped, they emit a decided "Pop!" and some green stuff. Some South Carolinians think they are "not from 'round heah", an alien life form......

So you have a bug problem. Ok here is the only and best way to kill those
pesky little disease ridden scum sucking varmints. Seal up your boat and run a 4 stroke gasoline engine. Small gasoline 4 stroke generators work the best. You can rent them by the 1/2 day, or just borrow one. Then just walk away for eight hours. The engine will run till there is no longer enough oxygen. The bugs and any other varmints will suffocate. You will not have any oily residue to deal with. Making clean up a breeze. Now remember not to breath when you open up the windows to vent the carbon monoxide. What ever you do be real careful, or you too could be Kaput. Don't use a diesel engine. The exhaust contains soot and that's a real pain to clean. Cockroach eggs hatch between 5 to 7 weeks. You will need to repeat this trick a few times. Once you have ridden the boat of all bugs. You need to keep it clean. You can still use a pesticide. You may only want to use it in areas that bugs make home and meals. REMEMBER THE BOAT WILL BE FULL OF CARBON MONOXIDE. CARBON MONOXIDE IS A SILENT KILLER, AND WILL KILL YOU ALSO UNTIL IT IS ALL VENTED OUT. Jack "Keith" wrote in message ... I've never had a roach problem on a boat before, but have got one now.

If you ever do get rid of them do not let corrugated cardboard boxes on
board ever again. Roaches love to lay eggs in those cozy little tubes. We get calls all the time from tenants who, after having been moved in for a few weeks, complain about roaches. Invariably we find that they packed their stuff in boxes they picked up from a grocery or liqour store and left them in a closet. Tenants who unpack everything and get rid of the boxes don't have roaches nearly as often. Keith wrote: I've never had a roach problem on a boat before, but have got one now.

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. grandma Rosalie |

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. Jack "Steve Christensen" wrote in message ...

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. Jack "Jack Rye" .# wrote in message news:WQSlb.33413$Rd4.31832@fed1read07... 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. Jack "Steve Christensen" wrote in message ...

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. Steve Christensen |

news:unTlb.33417$Rd4.8115@fed1read07... 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. I have this neighbor....can I hire you? |

And second, do NOT try this. Your chance of being asphyxiated is pretty good, like if you tripped getting away from the bucket. Getting rid of the bugs isn't worth risking your life.
