Aprehend should be stored at 77° F or below (the colder the better!), in its original packaging, for the full shelf life. This document on our website has a table that shows how short term heat exposure to various temperatures can shorten the shelf life https://rockwelllabs.com/wp-content/uploads/2026/02/Summer-is-coming.-Letterhead-1.pdf-1.pdf. Storing it refrigerated until used, after some short term heat exposure, can help offset the effect of the shortened shelf life. When the weather is warm, consider keeping the product in a small basic cooler if it is going to be left in the service vehicle during the daily route. Or bring it inside with you during the service visit. Don’t leave it in the service vehicle overnight, or on days when it isn’t being used. These simple steps will help preserve the full shelf life and efficacy of the product.
