I cannot imagine using diazinon on myself or an animal. In fact, I 
am surprised that you can legally. Amitraz is used for dips on large 
animals.  I cannot imagine using it in a flee collar on a pet. I 
would look for pyrethrins or synthetic pyrethroids.

No.  They shouldn't be absorbed.  And even if they were, pesticides 
are not being tested for.

As for someone's comments about numbing, this is not a known symptom 
of pesticide poisoning. Was it skin numbness or numbness in 
the entire foot? Perhaps it was a reaction to something else in the 
collar.  As for pets, an animal's hair prevents direct contact of the 
collar with skin. However, individual sensitiviy varies and pets can 
be affected as well.

Just a final plug. It is illegal - AND UNSAFE - to use any pesticide 
for uses other than what is stated on the label.  If human or equine 
use is not specified - DON'T DO IT.  Oops. Sorry for shouting.  It is 
just that my job is with pesticides (plants not animals).  And as we 
say - Always read the label!

off soapbox
