This all-natural mixture is harmful to rodents and other animals at first stage. It is not harmful to others after it is ingested. Same great bait (4oz) plus a natural mineral that is depleted within the first few minutes of digestion. In most cases it works faster than "poisons" and Non-target animals will not be harmed. Put some bait (smoothed out to see the licks and teeth) in several ridgid covered bait boxes with a mouse-sized hole near the bottom. Set these around your property. Place the containers in an area away from your house and outbuildings. Secure your bait boxes! (place and screw it inside a pallet, place it in a stone wall, woodpile, or screw it to something). Leave yourself access to monitor the bait. Look for dead target rodents. Mice and or rats may be lying nearby. This bait and method is designed to lure the rodents away from areas they are unwanted and die quickly before re-entering the build. Remember, Target Animal!
