  9. Avocado: Avocado contains persin, a substance that is toxic to many animals, including foxes. Avoid feeding them any part of the avocado plant.
  10. Mushrooms: Certain species of mushrooms are poisonous to foxes and can cause various health issues. It’s important to remove any wild mushrooms from areas accessible to foxes.
  11. Certain plants and flowers: Several common garden plants and flowers, including lilies, tulips, and daffodils, can be toxic to foxes if ingested. Ensure your garden is free from these potentially harmful plants.

Effects of Toxic Foods on Foxes’ Health

Ingesting toxic foods can have severe consequences for the health of foxes. The toxic substances found in chocolate, grapes, raisins, garlic, and onions can cause various symptoms ranging from gastrointestinal upset to organ damage. In some cases, ingestion of these substances can be fatal.

If you suspect that a fox has ingested any toxic food, it is crucial to seek veterinary care immediately. Prompt medical attention can help mitigate the potential harm caused and increase the chances of a successful recovery.

Effective Strategies to Discourage Foxes Without Harming Them

Securing Garbage and Compost

Foxes are attracted to easily accessible food sources such as garbage and compost. Secure your trash cans with tight-fitting lids and avoid leaving food waste exposed. Consider using animal-proof bins or storing garbage in secure enclosures to prevent foxes from being lured into your property.

Fencing and Barriers

Installing appropriate fencing can create a physical barrier that discourages foxes from entering certain areas. Choose fencing with a suitable height (at least 6 feet) and bury the bottom several inches into the ground to prevent foxes from digging underneath. Additionally, consider adding electric fencing or a protective wire mesh apron to deter climbing and digging.

Motion-Activated Devices and Deterrents

Utilize motion-activated lights, sprinklers, or noise-emitting devices to startle foxes and discourage them from frequenting specific areas. These devices help create an unpredictable environment that makes foxes uncomfortable and encourages them to seek alternative habitats.

Habitat Modification

Making your property less appealing to foxes can help deter them naturally. Remove brush piles, dense vegetation, and other potential hiding spots that foxes may use as shelter. Additionally, limit access to water sources by repairing leaks or securing ponds to discourage foxes from visiting your property.

Best Practices for Fox Management

Encouraging Coexistence with Foxes

  1. Providing Alternative Food Sources: One way to promote coexistence is by offering alternative food sources for foxes. This can include creating designated feeding areas with appropriate food items such as commercially available fox diets or raw meat. By providing foxes with a reliable food source away from human-populated areas, we can reduce their potential for conflict with humans.
  2. Creating Fox-Friendly Habitats: Foxes require suitable habitats to thrive. Designing fox-friendly environments involves preserving natural vegetation, providing shelter options like brush piles or dense shrubbery, and offering access to water sources. Creating these habitats in designated areas away from high human activity can help channel foxes toward more desirable locations.

Seeking Professional Assistance When Necessary

In some situations, professional assistance may be required to manage fox populations or address specific issues. Local wildlife management agencies or animal control organizations can provide valuable guidance and expertise. It is important to consult with these professionals who can offer humane and science-based solutions tailored to your specific circumstances.

What is the Best Poison for Foxes?

1. Sodium Fluoroacetate (Compound 1080)

Compound 1080, commonly known as sodium fluoroacetate, is a highly effective poison used in various pest control programs. It is known for its ability to selectively target foxes while minimizing risks to other animals when used correctly.

2. Phosphorus-Based Baits

Phosphorus-based baits are another option for controlling fox populations. These baits often contain toxic substances, such as zinc phosphide, that can be lethal to foxes when ingested.

3. Alpha-Chloralose

Alpha-chloralose is a non-lethal poison that can be used as an alternative to lethal options. It acts as a sedative, causing temporary immobilization of foxes. This approach allows for their safe capture and relocation to more suitable areas.

Smells that Foxes Dislike

Foxes have a keen sense of smell, and certain scents can be effective in deterring them from specific areas. By utilizing scents that foxes dislike, we can create an environment that discourages their presence.

Natural Scents that Can Deter Foxes

  1. Citrus: Foxes have an aversion to citrus scents. You can use citrus peels or citrus-scented sprays to create barriers or mark boundaries. Place these peels strategically around areas you want to protect, such as gardens or entry points, to deter foxes from approaching.
  2. Chili Pepper: The pungent smell of chili pepper can be unpleasant for foxes. Sprinkling chili powder or flakes around vulnerable areas can act as a deterrent. Take care to avoid direct contact with the chili powder yourself, as it can cause irritation.
  3. Ammonia: Ammonia has a strong and distinct smell that foxes find off-putting. Soaked rags or cotton balls dipped in ammonia can be placed strategically around your property, near den entrances or areas prone to fox activity. This can help create a scent barrier that discourages foxes from venturing too close.

Are Eggs Bad for Foxes?

Eggs are a natural part of a fox’s diet in the wild. Foxes are opportunistic hunters and scavengers, and eggs can provide a valuable source of nutrients. In moderate quantities, eggs are generally safe for foxes to consume.

However, it’s important to note that raw eggs may carry the risk of salmonella contamination, which can be harmful to both foxes and humans. Therefore, it is advisable to provide cooked eggs or remove the risk of contamination by boiling them before feeding them to foxes.

Can Foxes Eat Apples?

Apples are generally safe for foxes to eat in moderation. They can be a source of hydration and some essential vitamins. However, it’s crucial to remove any seeds and the core before offering apples to foxes.

Apple seeds contain small amounts of cyanide, which can be toxic to foxes and other animals if consumed in large quantities. Feeding small, seedless apple slices as an occasional treat can be a suitable addition to a fox’s diet.

What to Do If a Fox Is Poisoned

If you suspect a fox has ingested something toxic, take immediate action:

  1. Recognize signs of poisoning: Monitor the fox for symptoms such as vomiting, diarrhea, seizures, or abnormal behavior. If you notice any of these signs, act promptly.
  2. Seek immediate veterinary assistance: Contact a veterinarian specializing in wildlife or exotic animals as soon as possible. Explain the situation and follow their instructions for further assistance.
  3. Provide relevant information to the vet: Inform the veterinarian about the potential toxin ingested and any observed symptoms. This information will help them provide appropriate treatment and care.


Being aware of what is poisonous to foxes is essential for their well-being and safety. By understanding the risks associated with certain foods, substances, and plants, we can take proactive measures to prevent poisoning incidents.

Remember to keep harmful materials out of reach, dispose of toxic substances responsibly, and be cautious with plants and flowers in areas accessible to foxes. By prioritizing their health and safety, we can coexist harmoniously with these beautiful creatures.


Can foxes eat meat?
