Rat bait stations are dangerous because of the toxic chemicals contained in the bait. Coming into contact with the bait itself could lead to an accidental poisoning—the bait is toxic to both rats and humans upon ingestion. When you decide to use a rat bait station, you have to be extra careful to keep the bait stored where children and pets cannot possibly get to it.
Another downside to rodent bait traps is their effectiveness. Although they are very effective when discovered, rats don’t always come across them. You have to know the right places to leave them.
