Q: whats the shelf life for the poison?

22 days ago
1 Answer
  • A: Hi neighbor! Harris Dry-Up Mouse and Rat Killer has a functional shelf life of two to three years when stored unopened in a cool, dry place. While the active chemical ingredient remains stable for a long time, the food scent used to attract rodents will eventually go stale, causing pests to ignore the bait. To keep your bulk 16-pack powerful for as long as possible, make sure to keep the bucket lid tightly sealed away from humidity and strong chemical odors.

    A: No, this product is toxic to pets and is not safe for dogs or cats. It should be kept out of their reach and sight. To prevent accidental access by pets or children, the bait should be placed inside tamper-resistant bait stations.

A complete waste of money. I do not recommend it

5 months ago
There was nothing to like about this product every bait block that I had placed. They had gathered up and found a place to stash them that happened to be in my shoe. I had 28 blocks stuffed in a boot where they didn’t start out this product doesn’t kill them they laugh at it. In fact, there was a hole that they would go into that. I couldn’t reach by hand so I put a block of the poison on a board and moved it back towards the hole. A rat comes out, grabs the block of poison nibbles on it and takes it inside the hole. I still hear them at night trying to chew through the wall. Nothing seems to work to kill rats or mice this product is no different than any other one that claims to kill rats and mice. Very disappointed. As the rats have destroyed many cherished items. I’ve lost four year books from high school in college and several first edition books that they felt the need to chew apart. If anybody has a solution that works please share it with all of us.

No, I do not recommend this product.
