Yes which is why I haven’t used it any further than a couple years ago when they were just really running amok. Didn’t want to risk any of my chickens or other animals.The problem is the poison never goes away. A couple of weeks is one thing to kill the rats but the bodies will remain deadly as the original poison.
I am not so worried about them getting outside and dying as they tend to stay around their tunnels and homes. But my chickens are at risk.
They are so bad when I haul a bale of hay from the loft, mice run out from under the bales darn creatures.
I still want to do a bucket trap when I get a chance.
