There are several ways to keep squirrels away from your property, including:

1. Repellents: There are specific repellents on the market that can be purchased to help keep squirrels and other wildlife away. Jalapeño pepper mixed with vinegar produces a pungent smell that squirrels dislike, and there are also commercial repellent sprays available that use essential oils to create a smell and taste squirrels naturally hate.

2. Scare tactics: Motion-activated sprinklers, strobe lights, and ultrasonic or electronic sound repellents can all be effective in deterring squirrels from your property.

3. Cleanliness: Keeping your yard clean is important to prevent the invasion of other pests and deadly animals such as snakes. Clean away the fallen nuts and fruits that squirrels like eating, and make sure you keep the greenhouse locked at all times. If the squirrels are digging up the soil near the plants, consider laying gravel. This will make digging difficult and discouraging. Also, plant bulbs that squirrels do not like such as daffodils, allium, and snowdrops.

4. Physical barriers: Consider using a physical barrier, such as plastic netting, fencing, or chicken wire, to help keep your plants from harm. Hardware cloth, aluminum ducting, plastic pipe, netting, wire screening, chicken wire, or plastic bottles attached around the base of your feeders may help keep squirrels away.

5. Smells: Scents like white pepper, black pepper, garlic, and peppermint are naturally unpleasant to squirrels.

Its important to note that some of these methods may work better than others depending on the situation. It may be necessary to try a combination of tactics to keep squirrels away from your property.
