Reapplying repellent depends on the type and weather. Egg sprays need to be refreshed every two weeks. Soap pouches will last six weeks. Rain and humidity tremendously reduce effectiveness, and you will have to reapply it sooner, and/or adjust your schedule.

Always check the weather forecast before making any application. Heavy rainfall will wash away liquid repellents immediately. The humidity will evaporate scent more quickly. Ideally, liquid repellents should always be applied during dry periods where maximum adhesion is achievable. Likewise, check any repellent after it has been exposed to unusual weather conditions.

Seasonal changes influence duration of protection. Increase the frequency of spring growth and fall rut. Decrease application in winter when deer pressure is lower. Consider rotating types of repellents each month, so they (deer) do not adapt to a specific kind of animal repellent.

Track deer activity patterns to optimize schedules. Use trail cameras to monitor nighttime browsing. Note damaged plants within 48 hours of application. Increase frequency if damage occurs before the scheduled reapplication.

Utilize continuous protection by combining methods, such as layering soap pouches with garlic sprays. Consider alternating between egg and vinegar solutions. This strategy ensures that even when repellents diminish in strength between application intervals, there's still a substantial deterrence effect.

Proper reapplication ensures reliable garden protection. Follow these schedules to maintain effective barriers. Start implementing consistent routines tonight to ensure year-round deer control with uninterrupted coverage.
