Like it’s their food. Just poison the supplies and they die out. Of course I don’t think it’ll take much, and we humans should be fine with it. It just makes too much sense

Scalability is one reason. It would take a **lot** of medicine to dose everyone in the world.

Also, a lot of parasites can survive off more than one type of host. Bedbugs, for example prefer humans but can survive just fine off dogs and cats. You’d have to dose all of those as well, including the feral ones, to be sure of eradicating bedbugs
