The longevity of bug sprays can be significantly impacted by the storage conditions they are exposed to. Factors such as temperature, exposure to sunlight, and humidity play a crucial role in determining how long insect repellents remain effective. Storing bug sprays in cool, dry places away from direct sunlight can help prolong their shelf life. High temperatures can cause the active ingredients in bug sprays to break down more quickly, reducing their effectiveness. Similarly, exposure to moisture or humidity can lead to chemical degradation and compromise the potency of the product over time.
