There is a related question in Q & A, but it was not specifically answered. I'd like to know how much of the bait a large rat needs to eat for a lethal dose, and how long does it take, approximately, for a large rat to die after ingestion.
The SDS for First Strike Soft Bait Rodenticide states the LD50 (oral-rat): >2000 mg per kg. Time kill depends on how big the rat is and how much they ate but can range from 1- 5 days after consuming a lethal dose.
