My agency has 7 boxes of BTI Mosquito dunks and I could find no date of expiration. Is there a limit on the length of time they can be stored before they are no longer effective?
BTI Mosquito Dunks should be used within 2 years of the date of purchase. It is also important to store BTI Mosquito dunks out of direct sunlight and heat so that the product will not degrade.
