I have hears some animals like antifreeze as it is sweet. but deadly.
Antifreeze has the Same problem as with traps. You can’t control what drinks it. Neighbor’s cat, dog, child?
I think the antifreeze manufacturers put in some sort of extremely bitter agent now. I was working with some with my car, and it left a very bitter, hard to remove taste on my hands. I discovered that eating a sandwich, later, and had washed my hand very thoroughly with Orange GoJo followed by regular hand soap and a thorough rinsing.
Maybe someone else can confirm?
