Yup. Serious.

If other mammals can be vectors, gotta keep our pets home too, I guess. Cats get things dogs can't, but still...
I ordered some live mealworms and then learned they were shipping from NJ. It's Amazon. I only found out through the tracking number. I wrote to the guy (he apparently bought the postage but hadn't shipped yet) and asked him not to send them and that he should keep the money as a gift. Maybe that's over the top, but the Bubonic plague rode into Europe on the back of a flea. I very much doubt that darkling beetles have been studied and I just can't justify taking that chance.
