Some cats love to dig up flower beds, whilst others love to use container plants as their litter box.

Whilst you can’t keep these furry friends out of your garden completely, there are some ways to deter felines without causing any harm.

1. Clean up

Joe Rutter, garden expert at Garden Buildings Direct, told Express.co.uk: “Cats are attracted to food scraps and waste. It’s important to keep your garden free of such temptations. Regularly clean up any leftover food or spilt birdseed.

“Conduct routine garden maintenance. For instance, removing fallen fruits and vegetable scraps. Plus, some other organic matter may attract cats.

"Another clean-up tip is to dispose of garbage properly in secure containers. This simple habit helps big time, preventing cats from rummaging through it.”

These textures make it uncomfortable for the animals to walk on or dig and can be extremely effective.

3. Invest in an ultrasound device

The expert explained: “Ultrasonic devices emit high-frequency sounds that are unpleasant to cats. Such electronics make an effective deterrent without causing harm.

“Purchase and install ultrasound devices specifically designed to repel cats. Place them strategically around your garden to create a consistent coverage area. Follow the manufacturer’s instructions to maximise its effectiveness.”

4. Opt for pungent plants

Certain plants have extremely strong scents which “repel” cats, including lavender, rosemary, rue and coleus.

Plant these strategically around the garden, focusing on areas where cats dig or go to the toilet. The pro noted: “Properly care for these plants by providing adequate sunlight and water. Don’t forget to prune regularly to maintain their scent and effectiveness.”

5. Use coffee granules

The garden expert continued: “Take advantage of cats’ sensitivity to smells by using coffee granules. Spread coffee granules strategically in areas where cats are unwanted. The strong scent repels cats and discourages them from entering those areas.”

It’s recommended to reapply the granules periodically to ensure their effectiveness, important after heavy rain.

6. Citrus scents

Cats have an “aversion” to citrus scents, making them an extremely effective deterrent, according to the pro.

These can be placed in peel form or essential oils to create a “cat-free” garden. Joe said: “Scatter citrus peels or place them strategically in your garden beds. Or consider somewhere near potential entry points.

“You may also mix citrus essential oils with water and spray the solution around the garden. Remember to reapply after rain or as needed to maintain the scent’s potency.”

7. The scent of human hair

Cats are known to be deterred by the scent of human hair, as they see it as a huge threat.

Collect hair clippings from around the home and scatter them in the garden, prioritising areas where cats are frequently visiting.

8. Cover bare soil

Cats are attracted to bare soil as it is perfect for digging and using as a litter box.

Joe noted: “Cover exposed soil with mulch, stones, or a layer of netting to make it less appealing for cats to dig. Also, use raised beds or containers for your plants to minimise accessible areas of bare soil.”

9. Design obstacles

The expert continued: “Physical barriers can be highly effective in preventing cats from entering your garden. Consider installing fences, netting, or prickly plant borders to create deterrents.

“Choose visually appealing obstacles that blend with your garden’s aesthetics. For instance, use decorative fencing or trellises adorned with climbing plants. Also, ensure that obstacles are tall enough and securely installed to prevent cats from bypassing them.”

10. Motion-activated sprinklers

Install motion-activated sprinklers in the garden to startle and deter cats if no other method is working.

When they detect movement, the sprinklers will activate and spray water to create an unpleasant experience for feline intruders and they “won’t return”.

The pro concluded: “Strategically position the sprinklers to cover the areas you want to protect. This could be the flower beds or vegetable patches.”
