That is always a concern.  I don't think that the use here is off-label 
though.  I'll have to check.

As for the poisoning of  hawks, owls and other wildlife by, I assume through 
consumption of dead rodents rather than direct consumption of the bait, I 
would be surprised if they could get enough of the rodents in my situation 
to do them any harm, but I suppose it is theoretically possible.

I know we lost the use of strychnine used as gopher poison some time back 
for similar reasons, but I can easily see how the number of dead gophers 
after an application could be significant.  I seem to recall, too that 
strychnine has an exaggerated effect on birds.

As for mouse blocks in or under bee pallets, judging by consumption rates we 
observe and the number of untouched blocks, I would be really surprised if 
they have any impact on anything except the mice.  Leaving any poison lying 
around and accessible is always a concern, though.
