There is no official expiration date printed on each bottle. Generally, it is used immediately and then replaced every 3-4 months or at the very least 2 times per year. In the winter, just empty the KM Ant Pro Dispensers, wash them out with water and let them dry. Then just put them up until is warms up again. Then replace the Gourmet Liquid Ant Bait with new bait and start killing ants all over again.
