Pyrethrins & Pyrethroids

[Unknown Rider]

To Whom It May Concern,

I am currently looking for any information about pyrethrins &
pyrethroids and their effects on cold-blooded animals (reptiles). 
Specifically I would like to know if there have been any studies or if
there is anyone curre
ntly exploring this relationship.

Any and all information will help and be greatly appreciated.

Thanks
