Hi George,
I guess the bottom line is to look at the risks involved in wearing
Permethrin impregnated clothing and bedding in areas where there is a
high level of Malaria carrying mozzies, particularly those carrying
drug resistant strains of Malaria, and not. I think I would rather
take a risk with the Permethrin. The WHO puts the number of deaths
from Malaria at more than 1 million per year. I think the number of
deaths from Permethrin would be some what less than this.
Nothing is harmless. Even Oxygen is toxic and at this minute is
slowly killing you, it kills more people every year than any other
cause.
Cheers,
Carl Clifford

Hi all
I noted a couple of weeks ago that there was a discussion about
insect repellents for use in tropical areas. Permethryn was
mentioned as being very good and safe for use. I just came across a
container of poison for treating wood against borers: it contains
"100 g/l Permethryn 25/75" and warns of dire consequences of
contact of diluted solution to humans internally and externally,
and to dispose in non-cop land away from water supply. If this
poison is the same or similar to that being advocated for use when
birding in tropical areas, I'd be very worried from a personal
point of view and regarding the environment, particularly aquatic
habitats.
I also noted that a Birding-aus correspondent stated that
permethryn is "NOT carcinogenic in humans although some internet
ratbags claim it to". Having read the information on the wood borer
poison bottle and also a couple of reputable looking websites, I'd
still very worried about the effect of permethrin on humans and the
environment. If anyone knows if there are "safe" and "unsafe"
versions of permethrin or safe concentrations of the chemical,
please send a message to Birding-aus to clarify this situation.
Cheers
