What method could be used to deter chipmunks from gardens?

Using repellents is an effective method to deter chipmunks from gardens because these products are specifically designed to create an unpleasant environment for the animals, thus discouraging them from entering the area. Repellents can contain natural ingredients that have strong scents or tastes which are unappealing to chipmunks. By applying these substances in key areas, you can make your garden less inviting for these creatures, potentially preventing damage to your plants and landscaping.

While high fencing and ultrasonic devices may provide some level of deterrence, high fencing might be impractical or ineffective due to chipmunks' small size and ability to dig, and ultrasonic devices may not have consistent results in repelling wildlife. Planting specific herbs could act as a deterrent if chosen carefully, but it requires strategic selection and knowledge about which plants are less appealing to chipmunks, making it more complex than simply applying established repellents.
