He tested pyrantel ld50 for roaches.
Problem that roach cannot eat enough to die. It's just goes disoriented before it can eat enough.
Letal dose 50 means that this is when half of your animals already dead, and another half is still alive. It specific for every animal.
Anyways, when LD50 was tested for dogs - they must eat some crazy amounts of pyrantel to die. Its greater than 314 mg base per lb of body weight.
