Discussion Overview

The discussion centers around the effectiveness of Vienna Sausages as a method for killing cockroaches. Participants explore the potential reasons behind this phenomenon, including the ingredients and their effects on the insects. The scope includes experimental observations and hypotheses regarding the toxicity of the sausages.

Discussion Character

  • Exploratory
  • Experimental/applied
  • Debate/contested

Main Points Raised

  • One participant describes a method of using Vienna Sausages to kill cockroaches, noting that the insects appear to crawl into the can and die face down.
  • Another participant questions the discovery, suggesting that the roaches may be attracted to the contents and could either drown or be poisoned by something in the sausages, such as sodium nitrite or other preservatives.
  • Concerns are raised about the variables involved in the experiment, including the specific ingredients and whether the results are consistent across different brands of Vienna Sausages.
  • A later reply compares the situation to tar pits, suggesting that the roaches may be unable to escape once they enter the can.
  • One participant speculates that the cockroaches might be receiving a lethal dose of sodium compounds from the sausages.
  • Another expresses intrigue at the discovery, noting a potential advantage over conventional poisons, as the dead cockroaches might be safe for other animals to consume.
  • There is a light-hearted inquiry about whether this method might also work on mice and rats.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the reasons behind the effectiveness of Vienna Sausages in killing cockroaches, with multiple competing hypotheses and uncertainties remaining in the discussion.

Contextual Notes

There are limitations regarding the assumptions made about the ingredients and their effects, as well as the lack of controlled experimentation to verify the claims made by participants.

Empty a can of Vienna Sausages, except for the broth that remains. Leave it out, in the upright position, for your cockroaches. You will find that they crawl into the can and die, and so many victims there are. The question is why. They apparently do not attempt to crawl out because there are none dead on their backs. They're all face down. I looked at the ingredients: meat products, spices, and sodium nitrite. I don't know why it works but it's a great discovery!

How did you discover this?

It looks like the roaches are attracted to the can contents - so either they get stuck and drown or there is something in the tins that is toxic to them. (Or someone is playing a joke.)

Sodium Nitrite is toxic.
Maybe it contains salt or some other preservative in high-ish quantities?

What are the "spices"?
Could there be an undeclared preservative in there too?
Is the food acidic? Do they use an acidity regulator?
Does it work with all brands or are some better than others?
Is the experiment repeatable?

I think there are too many variables to tell.

The way you describe the situation,
THEY HAVE FALLEN AND CAN NOT GET OUT.
This would be the way the tar pits worked.
 
Intelligence is not the most endearing trait of roaches. But, they do the 'be fruitful and multiply' thing with great efficiency. My guess is they get a lethal dose of sodium compounds from the sausages.

It's an intriguing discovery, certainly. This seems to have a big advantage over conventional poisons---the victims of Vienna Sausages presumably being safe to feed to birds and lizards! http://imageshack.com/a/img29/6853/xn4n.gif

I might give it a try next summer.

Does it also work on mice & rats, have you noticed? :-p
