6 Best Fox Deterrents of 2025

Ultrasonic deterrents are a humane way to deter foxes from your garden. The Pestbye® Motion Activated Fox Repellent emits a high frequency sound that’ll irritate foxes but is inaudible to most humans.

Available as a set of 2, each with a range of 10 m and covering an arc of 110°, this is a great option for large gardens. Each unit has a PIR motion sensor which detects the movement and body heat of unwanted intruders.

The deterrents come with a zinc-coated ground stake as well as a hanger. They can be pushed into the ground or fitted to a wall or fence. The units are weatherproof and can be left outside year-round. They require 4 x AA batteries each, with the batteries generally lasting up to 6 months.

With a range of adjustable settings, these ultrasonic repellers are suitable for most gardens. The sensor is adjustable to help prevent false detections and there’s also a dial to adjust the frequency. Whether you’re trying to deter foxes, cats or rodents, the frequency can be altered accordingly.

Therefore, these are some of the best fox deterrents if you want ultrasonic units with adjustable frequencies. They have increased versatility as they can be set to deter different animals.

When it comes to deterring the most stubborn foxes, ultrasonic frequencies or LED lights may not be enough. The Defenders STV415 Jet-Spray Pond & Garden Protector uses water to actively scare foxes away, as opposed to just deterring them.

This jet-spray is motion activated, using a reliable PIR sensor with a range of up to 10 m that covers a 120° arc. For smaller gardens, the detection range can be reduced, so it won’t be accidentally activated by movement in your neighbour’s garden, for example!

It’s worth noting however, that the motion sensor is very sensitive and can be triggered in windy conditions by the movements of trees and bushes. To turn off the deterrent (for instance if you are using the garden and don’t want to get soaked!), simply turn the water off at the mains.

Once the PIR sensor is triggered, this fox repeller shoots a jet of water out to scare the unwelcome visitor. It makes a relatively loud noise in the process, which also surprises the animal. The water pressure and angle is adjustable, and you should find after just a couple scares, foxes stop returning to your garden.

This deterrent is very easy to set up, although it requires a little more work than solar-powered models. You’ll need to attach a hose (the deterrent has a standard hose fitting that will connect to most garden hoses) and insert 2 x AA batteries. It’s best installed away from direct sunlight (as this may trigger the motion sensor), and it should also be taken inside if temperatures are expected to drop below-freezing.

This deterrent doesn’t require mains power which makes it very easy to use, and it’s a step up from ultrasonic deterrents when it comes to effectiveness. While animals can get used to ultrasonic frequencies, a rapid jet of water has an added element of surprise. It’s one of the best fox deterrents if you want something truly effective and surprising, though it requires a bit more effort to set up than others.

These Cactus Fox Deterrent Wall Fence Spikes are a great choice if you know exactly where foxes are gaining access to your garden. These spikes can be used to make your garden difficult to access and to put animals off from visiting. They work best when combined with other deterrents.

This deterrent consists of plastic spikes which can be laid across the tops of fences to prevent foxes, cats and other intruders from accessing your garden in this way. They also add an extra layer of security to your home, helping to deter opportunistic thieves as well.

While these spikes cause discomfort, they aren’t intended to physically harm foxes or cats – the intention is that they are uncomfortable to walk on.

These fence spikes come in a pack of 20 strips, measuring 45 cm long and 4.5 cm wide. They can be placed on even very narrow fences, or grouped together for wider areas. They can also be cut to size, reducing the width further. Each spike measures 1.5 cm across. They are amongst the sharpest on the market so, although they are made from plastic, a lot of care needs to be taken when installing.

These spikes are relatively easy to install although screws will need to be purchased separately. They are very low maintenance – once they’re in place, that’s your job done. They are fully weather resistant, made from hard UV resistant plastic which won’t weaken if exposed to rain, frost or icy conditions.

Overall, these fence spikes are most effective when combined with additional deterrents. However, these fence spikes are one of the best fox deterrents if you know that foxes are climbing into your garden; they can be used to block off certain routes and make it harder for foxes to gain access.

If you’re after an ultrasonic fox deterrent on a budget, the YurDoca Ultrasonic Fox Repellent is a good option to consider. It’s inexpensive, yet boasts many of the same features as pricier models. Overall, it’s an effective repeller that can humanely drive away unwelcome visitors, including both foxes and cats.

It works using a reliable motion sensor. Once a fox or other animal has been detected, the repellent will emit an ultrasonic frequency that deters the animal from sticking around. As an additional deterrent, there’s also an LED flashing light.

Covering an angle of 110° horizontally and a 50° arc from top to bottom, this repeller covers a reasonably small area so needs to be placed near paths frequented by foxes. The range is 8 m, and it can detect both small and large animals.

In terms of adjustability, this fox repellent isn’t quite as advanced as others on the market. There’s no option to alter the frequency, but, nevertheless, the set frequency does a good job of deterring foxes (and cats!).

To install this unit, simply push it into the ground or hang it on a fence. It’s best installed in direct sunlight (or moved into the sun during daytime) in order to charge effectively, As this is the only way to power the unit, you may find it slightly less effective in the winter months. The unit is, however, fully weatherproof – able to withstand snow, ice, rain and wind.

Considering the price and capabilities of this unit, it’s one of the best fox deterrents to buy on a budget. Even though the ultrasonic frequency isn’t adjustable, it still seems effective against foxes nonetheless.

The Solar Predator Control Lights Fox Deterrent offers a safe and humane way to help deter foxes from your garden. These lights spook animals into thinking they’re being watched and are ideal for gardens that are visited by a lot of different wildlife.

This set consists of four units, each containing 2 LED lights. At night, the lights turn on automatically and blink in order to startle animals. They require very little maintenance as they run off solar power meaning there are no batteries to charge. Generally speaking, they hold enough power to last throughout the night and can be seen by intruders up to 243 m away.

These lights are very easy to use and install. Simply push each light into the ground or hang the units on a wall or fence. They can be spread around your garden to cover the entire area, or placed in a specific area that you know foxes like to visit. These lights are safe, eco-friendly and contain nothing that will harm either humans or animals.

Providing they are placed in a relatively sunny area, you should find these lights require little attention. They are waterproof, and can be used in the rain, with a rating of IP44.

While it may take some trial and error to work out which is the best fox repellent for your garden, these lights are worth considering if you don’t want to use ultrasonic frequencies or water jets. They work purely on the element of surprise, unnerving foxes and making them think they are being watched.
