How to identify wildlife damage

Identifying wildlife damage in UK gardens starts with observing the type, height and timing of the damage. Browsing and stripped growth up to 1.5 metres high is typically caused by deer, clean angled cuts close to ground level point to rabbits, digging and disturbed soil suggest fox activity, and droppings or pecked plants usually indicate pigeons.

How DeerEx Works

Deer typically browse gardens because plants are easy to access and provide fresh, nutrient-rich growth. DeerEx works by applying a scent signal to plants and key access routes that deer instinctively avoid, encouraging them to move on and feed elsewhere.

Best application areas:

New growth, buds, shoots and leaf tips

Outer edges of borders and beds

Entry points, fence lines, hedges and deer pathways

High-value plants (roses, shrubs, young trees)

Ready-to-Use Spray vs Concentrate Powder

Choose the format that matches your garden and routine:

Ready-to-Use Deer Repellent Spray
Best for quick protection with no mixing — ideal for smaller gardens and fast application.

Concentrated Deer Repellent Powder
Best value for medium-to-large gardens — mix with water to make a larger volume of ready-to-use spray.

How to Apply (Simple Plan)

Apply to vulnerable plants (buds, new leaves, tips, shoots).

Apply around access routes where deer enter the garden.

Reapply after heavy rain and during periods of rapid growth.

Maintain a light “buffer” around favourite plants for continuous protection.
