How Long Do Rat Baits Expire?
WouterThe first thing you should do if you have rat poison on hand is to store it properly. Rat poison expires after one year, but you can prolong its effectiveness by keeping it in a cabinet or airtight container. Be sure to lock the cabinet and keep children and pets away from it.
Rodenticide, which is also known as rat poison, is a type of chemical that’s used to kill mice and rats. It’s often used as a food poison, and the chemical components in it are not meant to kill the rodent immediately, but to remain lethal for days or even weeks. In fact, some rodenticides will become useless after some time, and you may have to buy a new one.
Rat poison, when properly stored, can last for a year, but it’s still best to replace the bait every month to maintain its effectiveness. Rat poison should always be stored in an airtight container, since it can still contain the poison. However, it’s important to wash your hands after handling it, because the chemicals in it can be lethal to humans.
If you use baits, make sure to check with your pest controller. They’ll know when to replace them and how often you need to replace them. You should change the bait if the rodents return after an absence of several months. In addition, it’s important to check the expiration date on the bait station. If it is outdated, you should dispose of it.
