Key Takeaways
- Raccoon feces in pools can contain Baylisascaris procyonis, a roundworm parasite that poses serious health risks to humans and pets.
- Standard chlorine levels in most pools do NOT kill raccoon roundworm eggs — you need specific cleanup procedures to stay safe.
- The CDC recommends filtering, superchlorination, and careful manual removal rather than simply shocking the pool.
- Raccoons are attracted to pools as water sources and latrine sites, so prevention requires blocking access and removing attractants.
- Professional wildlife removal is the safest long-term solution if raccoons repeatedly contaminate your pool.
Finding raccoon poop in your pool is more than just disgusting — it’s a genuine health emergency. Raccoons frequently use swimming pools as communal latrines, depositing feces that can carry Baylisascaris procyonis, a dangerous roundworm parasite capable of causing severe neurological damage in humans. Unlike many backyard pests such as roof rats, raccoons present a unique poolside threat because their parasites survive standard chlorine treatment. If you’ve spotted droppings floating in your pool or sitting on the deck, you need to act quickly and carefully. This guide covers everything you need to know — from identifying raccoon feces and understanding the health dangers, to step-by-step cleanup, proper disinfection, and proven prevention strategies to keep raccoons away from your pool for good.
Why Do Raccoons Poop in Pools?
Raccoons are creatures of habit, especially when it comes to where they relieve themselves. They establish communal latrines — specific spots where they repeatedly defecate. Unfortunately, your pool often meets all their criteria for an ideal latrine site.
Pools attract raccoons for several reasons:
- Water source: Raccoons drink from pools regularly, especially during hot, dry months.
- Shallow steps and ledges: Pool steps and shallow entry points mimic the shallow water edges raccoons naturally prefer for defecating.
- Routine behavior: Once a raccoon uses your pool as a latrine, it will return night after night to the same spot.
- Nearby food sources: Trash cans, pet food bowls, and fruit trees near your pool area draw raccoons in close proximity.
Raccoons are nocturnal, so you may never actually see the culprit. Instead, you’ll find the evidence floating in the water at dawn. Understanding this behavior is the first step toward stopping it.

How to Identify Raccoon Feces in Your Pool
Before you begin cleanup, you need to confirm that the droppings actually belong to a raccoon. Misidentifying the source could lead you to underestimate the health risk or apply the wrong cleanup protocol.
What Does Raccoon Poop Look Like?
Raccoon droppings are tubular and roughly 2 to 3 inches long. They resemble small dog feces but are often darker in color. Fresh raccoon poop may contain visible undigested food — berry seeds, insect parts, or bits of fruit are common. In water, the droppings may break apart quickly, leaving dark debris scattered across the pool floor or floating on the surface.
Raccoon Poop vs. Other Animal Droppings
| Animal | Droppings Size | Shape & Appearance | Typical Location |
|---|---|---|---|
| Raccoon | 2–3 inches | Tubular, dark, may contain seeds or food | Pool steps, shallow ledges, deck edges |
| Opossum | 1–2 inches | Smooth, tapered, similar to cat droppings | Rarely in pools; usually on ground |
| Squirrel | Less than 1 inch | Small pellets, light brown | Near trees and fences, not pools |
| Bird | Varies | Liquid, white/dark mix | Pool surface, deck, furniture |

Health Risks of Raccoon Poop in Your Pool
This is where the situation turns from gross to genuinely dangerous. Raccoon feces carry several pathogens that can infect humans and pets, and the pool environment doesn’t neutralize most of them.
Baylisascaris Procyonis (Raccoon Roundworm)
Baylisascaris procyonis is the primary threat. This roundworm parasite lives in raccoon intestines, and its eggs are shed through feces. A single raccoon dropping can contain millions of roundworm eggs. Once ingested by a human — even accidentally through contaminated pool water — the larvae can migrate through the body and invade the brain, eyes, and organs.
Symptoms of Baylisascaris infection include nausea, fatigue, loss of coordination, and in severe cases, blindness or coma. Children are at highest risk because they’re more likely to swallow pool water while swimming. The critical fact: Baylisascaris eggs are not killed by standard pool chlorine levels. This is why proper cleanup goes far beyond a simple shock treatment.
Giardia and Leptospirosis
Beyond roundworm, raccoon feces can also carry Giardia lamblia, a parasite that causes severe gastrointestinal illness. Leptospirosis, a bacterial infection spread through raccoon urine, can also contaminate pool water and cause kidney damage, liver failure, and meningitis. Both pathogens can survive in water for extended periods, making prompt pool cleanup essential.
Step-by-Step: How to Clean Raccoon Poop From Your Pool
The CDC has published specific guidance for cleaning pools contaminated with raccoon feces. Follow these steps carefully — do not take shortcuts.
Step 1: Protect Yourself
Wear disposable gloves and avoid touching your face. If the feces are on the pool deck, wear shoe covers or designate shoes you can disinfect afterward. Do not allow children or pets near the pool during cleanup.
Step 2: Remove the Feces
Use a net, bucket, or plastic bag turned inside out to remove all visible fecal matter. Do not use your pool’s vacuum or filtration system to pick up the droppings — this will contaminate the filter. Double-bag the waste in sealed plastic bags and dispose of it in your outdoor trash.
Step 3: Clean or Replace the Filter
If any fecal matter has passed through your pool’s filtration system, backwash the filter thoroughly. For cartridge filters, replace the cartridge entirely. Raccoon roundworm eggs are microscopic, so even water that looks clean may be contaminated if the feces dissolved before you found it.
Step 4: Superchlorinate the Pool
Raise your pool’s free chlorine level to at least 20 parts per million (ppm) and maintain that level for at least 8 hours. Keep the water temperature above 77°F during this process. This level of chlorination can inactivate Giardia cysts, though it is important to note that even superchlorination may not fully destroy Baylisascaris eggs. However, the combination of filtration and high chlorine significantly reduces the risk.
Step 5: Test and Rebalance
After the superchlorination period, test your water chemistry. Allow chlorine levels to drop back to the normal range of 1–3 ppm before anyone swims. Rebalance pH, alkalinity, and other levels as needed. Do not rush this step.
How to Keep Raccoons Away From Your Pool
Cleaning up after raccoon contamination is stressful and costly. Prevention is far better than repeated cleanup. Here are the most effective strategies to raccoon-proof your pool area.
Install a Pool Cover
A sturdy, tightly secured pool cover is the single most effective barrier. Raccoons prefer easy access to water. A solid safety cover that can support weight will prevent them from reaching the water surface. Mesh covers may work but can sag and collect rainwater, which raccoons will still visit.
Remove Food Attractants
Raccoons don’t visit your pool in isolation — they’re in your yard because something else drew them there first. Secure trash cans with locking lids. Bring pet food bowls inside at night. Pick up fallen fruit from trees. Eliminating food sources makes your entire property less appealing. Many wildlife species share these attractants, which is why homeowners dealing with skunk problems often find the same strategies effective.
Use Motion-Activated Deterrents
Motion-activated sprinklers and lights can startle raccoons and discourage repeat visits. Place them near pool entry points, deck edges, and along fence lines where raccoons typically travel. Rotate the position of deterrents periodically — raccoons are intelligent and can learn to ignore stationary devices.
Trim Trees and Block Access Points
Raccoons are excellent climbers. Overhanging tree branches give them easy access to your pool area, deck, and even your roof. Trim branches back at least 6 to 8 feet from any structure. If you have a fence, consider adding a roller bar or electric wire along the top to prevent climbing. Squirrels use these same arboreal highways, so if you’ve noticed squirrels getting into your house, trimming trees will help address both problems simultaneously.
When to Call a Professional for Raccoon Poop in Your Pool
Some situations require more than a DIY approach. You should contact a professional wildlife removal service if:
- Raccoon droppings appear in your pool repeatedly, indicating an established latrine.
- You find a raccoon latrine on your property — on the roof, in the attic, or near the pool deck.
- You suspect raccoons are nesting on your property, such as in your attic, shed, or under a deck.
- A family member or pet has been exposed to contaminated pool water and shows symptoms of illness.
- You’re unable to identify the animal responsible for the contamination.
Professional wildlife control technicians can trap and relocate raccoons humanely, sanitize latrine sites with specialized equipment, and install exclusion measures that prevent re-entry. Attempting to handle a raccoon on your own can result in bites, scratches, and exposure to rabies.
If raccoons have become a recurring problem on your property, professional intervention is the most reliable path to a permanent solution. On Demand Pest Control offers expert wildlife removal services designed to safely eliminate raccoon problems and protect your family’s health.
Can Raccoon Poop in a Pool Make You Sick?
Yes — and the risk is higher than most homeowners realize. Even a single exposure to contaminated water can lead to infection, particularly in young children who tend to swallow water while playing. The incubation period for Baylisascaris can be one to four weeks, making it easy to miss the connection between a swim and later symptoms.
Symptoms to watch for after potential exposure include:
- Nausea, fatigue, and loss of appetite
- Muscle aches and fever
- Difficulty with coordination or balance
- Vision changes or eye irritation
- Abdominal pain or diarrhea (more commonly linked to Giardia)
If anyone in your household develops these symptoms after swimming in a pool that may have been contaminated, contact your healthcare provider immediately. Early treatment can significantly improve outcomes for roundworm infections.
Protecting Your Yard From Raccoons and Other Wildlife
Raccoon pool contamination is often just one symptom of a larger wildlife problem. If raccoons feel comfortable enough to use your pool as a latrine, they’re likely also exploring your trash, garden, and home exterior for food and shelter.
A comprehensive wildlife prevention strategy includes:
- Securing all entry points: Seal gaps in soffits, vents, and foundations where raccoons and other animals could enter.
- Maintaining your yard: Keep grass trimmed, remove brush piles, and eliminate ground-level hiding spots.
- Addressing multiple species: Many wildlife issues overlap. Homeowners luring raccoons may also attract other animals. Understanding what baits attract groundhogs or other burrowing animals can help you take a broader approach to yard protection.
Taking a proactive, whole-property approach to wildlife management will reduce raccoon visits to your pool and minimize the chance of finding droppings in the water again. When prevention measures aren’t enough on their own, don’t hesitate to reach out to a licensed pest and wildlife control professional who can assess your property and implement lasting solutions.
Frequently Asked Questions
-
Can pool chlorine kill raccoon roundworm eggs?
No. Standard pool chlorine levels (1–3 ppm) do not kill Baylisascaris roundworm eggs. Even superchlorination at 20 ppm may not fully destroy them. The CDC recommends physically removing the feces, backwashing or replacing the filter, and superchlorinating to reduce overall contamination risk.
-
How often do raccoons return to the same pool to defecate?
Raccoons are habitual latrine users. Once they establish your pool as a latrine site, they will return nightly until something disrupts the pattern. Physical barriers like pool covers and motion-activated deterrents are the most effective ways to break this cycle.
-
Is it safe to swim after finding raccoon poop in the pool?
No, you should not swim until you've completed the full cleanup and disinfection process. Remove all fecal matter, backwash or replace the filter, superchlorinate to 20 ppm for at least 8 hours, and then allow chlorine to return to safe swimming levels of 1–3 ppm before re-entering the water.
-
What should I do if my dog drank pool water contaminated by raccoon feces?
Contact your veterinarian promptly. Dogs can contract Baylisascaris, Giardia, and leptospirosis from contaminated water. Watch for symptoms such as lethargy, vomiting, diarrhea, or coordination problems. Early veterinary treatment offers the best chance of recovery.
-
Do raccoons carry rabies in addition to the parasites found in their feces?
Yes, raccoons are one of the primary carriers of rabies in the United States. While rabies is transmitted through bites and scratches rather than feces, this is another reason to avoid direct contact with raccoons. Always call a professional wildlife removal service rather than attempting to handle a raccoon yourself.
-
Will a pool fence keep raccoons out?
A standard pool fence alone is unlikely to stop raccoons because they are skilled climbers. However, combining a fence with a roller bar system on top, motion-activated deterrents, and a solid pool cover creates a layered defense that significantly reduces raccoon access to your pool area.
