Raccoons might seem harmless as they scavenge through your trash or wander through your yard, but they can pose a significant risk to both your pets and your family. One of the lesser-known dangers associated with raccoons is raccoon roundworm (Baylisascaris procyonis). This zoonotic disease can infect pets, and in rare cases, humans, leading to severe health issues.
If you’re a pet owner or homeowner, understanding the risks, recognizing symptoms, and taking preventive actions can protect your loved ones and maintain the safety of your home. This blog will guide you through what raccoon roundworm is, how it spreads, and how to safeguard your pets and property.

What is Raccoon Roundworm?
Raccoon roundworm is a parasite commonly found in raccoons, particularly in North America. According to the Centers for Disease Control and Prevention (CDC), as many as 70–80% of raccoons in some areas are infected. While raccoons are the natural host of this parasite, other mammals, including dogs and cats, can accidentally ingest roundworm eggs and become infected.
The eggs are primarily shed in raccoon feces, where they can last for years if conditions are favorable. Once ingested, the larvae migrate through the body, potentially causing organ damage or neurological issues. This makes roundworm not only a threat to pet health but also a concern for human safety.
Understanding the Life Cycle of Raccoon Roundworm
To appreciate the risks posed by raccoon roundworm, understanding its life cycle is essential. Pets, especially curious dogs that roam outdoors, are at higher risk of accidental ingestion, making preventive measures critical for their well-being.
- Egg Shedding: Raccoons infected with roundworm shed millions of eggs in their feces. These eggs are not immediately infectious but become so within 2–4 weeks after being deposited.
- Transmission: Eggs can contaminate soil, water, or surfaces where raccoons frequent, such as gardens, backyards, or even attics. Pets are often exposed when they sniff or eat contaminated soil, grass, or even raccoon feces.
- Larval Migration: Once ingested, the eggs hatch into larvae inside the host’s intestine. These larvae can migrate to other tissues, including the brain, eyes, and spinal cord, causing severe health problems.
Signs and Symptoms of Raccoon Roundworm Infection in Pets
Early identification of infection in pets is crucial to prevent long-term health complications. However, raccoon roundworm infections are often tricky to diagnose, as symptoms can vary depending on the severity of the larval migration.
Common Signs to Watch Out For:
- Digestive Issues: Vomiting, diarrhea, or a bloated abdomen.
- Behavioral Changes: Unusual lethargy, restlessness, or aggression.
- Neurological Symptoms: Tremors, loss of coordination, or partial paralysis indicate severe cases.
If you notice these symptoms in your pet, immediate veterinary attention is critical. Early intervention can significantly improve outcomes and prevent further complications.
How to Protect Your Pets from Raccoon Roundworm
Fortunately, there are numerous steps you can take to protect your pets and minimize the risk of exposure to raccoon roundworm.
1. Secure Outdoor Spaces
Raccoons are drawn to food sources near homes. Keep outdoor dining areas clean, store trash in raccoon-proof containers, and remove pet food or birdseed from your yard to discourage raccoon visits.
2. Dispose of Waste Safely
Raccoon feces are the primary source of roundworm eggs. Use gloves to handle and safely dispose of any feces found on your property. Clean contaminated areas with boiling water or a torch flame to kill the eggs.
3. Regular Veterinary Check-Ups
A consistent veterinary care schedule can help identify potential infections early. Your vet may recommend de-worming treatments, which can address and prevent various parasitic infections, including roundworm.
4. Avoid Contact with Raccoons
Never approach or feed raccoons. Teach children to avoid unfamiliar animals and discourage your pets from chasing them.
5. Use Raccoon Repellent
Commercial raccoon repellents or natural deterrents, such as ammonia-soaked rags, can help keep raccoons away from your property. Sprinkle repellents around garden beds, trash cans, and entry points.
6. Keep Your Home Animal-Proof
Inspect your home for potential raccoon entry points, such as gaps in the roof, vents, or chimneys. Seal these areas to prevent raccoons from nesting in your attic or crawl spaces.
The Importance of Early Detection and Treatment
If your pet is exposed to raccoon roundworm, early detection can make all the difference. Your veterinarian may perform stool tests, imaging, or bloodwork to confirm the presence and severity of the infection. With appropriate anti-parasitic treatments and supportive care, most pets recover well.
Ignoring the problem can lead to escalating health issues that might result in more invasive medical treatments or permanent damage. Staying vigilant and acting quickly ensures the best outcome for your fur family.
