Dosage and receiving very good

I have the whole time recalculated to get also get a feel for the toxicity to pets and people:
The baits contain the active substance brodifacoum 0.005%. Thus, each block contains 20g 1mg brodifacoum. The lethal dose in mice is 0.4 mg / kg (Source: [...]). A 35g heavy fire mouse would accordingly only 0,0875mg take up to die for. This corresponds to less than 10% of a block. Thus, it seems to be dosed adequate for my purposes. The bait is also well received.
But you should be careful because the lethal dose in domestic animals and birds is low. Probably also in humans. Taking 0.1 mg / kg for the man. Would it suffice if a 10kg lightweight toddler takes a block to die. So, please be careful to use!
