Rat poison is a lot less expensive in bulk which is why I wanted to know specifically which poison works the best under your circumstances - because I'd have a lot of it.
In the reviews it seems some work best outdoors when they get wet and others work better indoors, and some make them bleed and others knock them out cold. Some say they taste like fish and others say the mice like the flavor.
In the end they all must work (or they wouldn't sell them) so it's probably just as well that nobody here reads the package when they use the stuff, but normally this group has years of experience so I didn't expect that.
Anyway, I tried to buy and ship the Amazon TomCat bromadiolone and diphacinone (yellow and green blocks) but I'm having trouble getting it shipped by Amazon to the nanny state of the recipient.
I may ship it to my non-nanny state and then just put it in my luggage the next time I go there but I don't know what they'll think at the airport scanner if they see pounds of rat poison blocks in my luggage.
