Some internet sources suggest that it may be more toxic to cats than, say, humans or dogs.

== Breakdown in sunlight ==
The statement that pyrethroids breakdown in sunlight after two days is not supported by the citation. Indeed elsewhere the US EPA has stated that pyrethroids have a half life of 30 days in the soil, and there is strong evidence that microbial action is the primary means of breakdown.

Clean Up

The introduction section

The introduction section is rather long, providing detailed information that would be better as (a) new section(s). There is also explanation of related substances that could very easily be removed, instead just having the link to the article for more information.

Example: The sodium channel consists of a membrane protein with a hydrophilic interior; this interior is effectively a tiny hole which is shaped exactly right to strip away the partially charged water molecules from a sodium ion and create a thermodynamically favorable way for sodium ions to pass through the membrane, enter the axon, and propagate an action potential.

The previous sentence has a link to the article for sodium channels.

I would make changes but I don't trust my own sense of formatting and descriptive helpfulness. --184.57.79.116 (talk) 08:40, 2 May 2010 (UTC)[reply]
