Raccoon Feces & Roundworm Information
Raccoon Roundworm in Virginia: Risks From Raccoon Latrines & Feces
Raccoons often return to the same places to defecate, creating communal toilet areas known as latrines. When those sites are in attics, garages, rooftops or other areas around a home, the accumulated feces can create a contamination concern—including possible exposure to Baylisascaris procyonis, the raccoon roundworm.
Human infection is rare, but it can be severe. This article explains how the parasite is spread, why raccoon latrines deserve careful attention, and when professional cleanup or medical guidance may be appropriate.
Understanding the risk
How Raccoon Roundworm Exposure Happens
Raccoons are the primary host of Baylisascaris procyonis. Infected animals pass eggs in their feces, and those eggs can later become infective in the environment.
Raccoon latrines
Raccoons commonly reuse the same defecation sites. Latrines may occur on rooftops, decks, woodpiles, garages, attics and other raised or sheltered surfaces.
Microscopic eggs
Roundworm eggs cannot be seen with the naked eye. A pile of raccoon feces does not have to look unusual to represent a potential contamination concern.
Accidental ingestion
Human infection occurs when infective eggs are accidentally swallowed from contaminated soil, objects, hands or other materials—not from simply seeing a raccoon.
Why cleanup matters
Attic Raccoon Latrines Can Create More Than an Odor Problem
Repeated raccoon use can leave feces, urine staining, nesting debris and damaged insulation behind. When a latrine develops inside an attic or other enclosed area, the cleanup problem may extend beyond the visible droppings.
The CDC recommends careful handling of contaminated materials and notes that prompt removal of newly deposited feces can reduce the chance that roundworm eggs have time to become infective.
Human Infection Is Rare but Can Be Serious
The CDC describes human baylisascariasis as uncommon, but infection can become severe if larvae migrate into the eyes, organs or central nervous system.
Anyone concerned about a possible ingestion or exposure should contact a healthcare provider rather than relying on a wildlife company to assess medical risk.
Reducing contamination risk
What to Do When You Find a Raccoon Latrine
Keep people and pets away
Until the area is addressed, limit access—especially for young children and pets that may contact contaminated materials.
Avoid spreading dry material
Dried feces and debris should be handled carefully so contaminated material is not unnecessarily disturbed or carried into other parts of the home.
Address the raccoon problem too
Cleanup alone will not solve an active structural problem. The raccoon entry point and any conditions allowing repeat access should also be identified and corrected.

Raccoon Removal and Contaminated Attic Areas
When raccoons have been using an attic, the job may involve animal removal, inspection of the entry point, exclusion or repair work, and evaluation of contaminated insulation or latrine areas.
Medical questions are different
Possible Ingestion or Exposure?
If you believe you or a child may have swallowed material contaminated with raccoon feces, contact a healthcare provider promptly. Wildlife-removal professionals can address the animal and property problem but should not diagnose or manage human infection.
Why This Post Is Still Useful
The original article focused on raccoon roundworm in the Richmond and Charlottesville areas. The location-specific wording was dated, but the underlying issue remains relevant anywhere raccoons create latrines around Virginia homes.
The updated version therefore focuses on the durable homeowner question: what raccoon roundworm is, how exposure occurs, and why raccoon feces in or around a structure should be handled carefully.

Frequently Asked Questions
What is raccoon roundworm?
Baylisascaris procyonis is an intestinal roundworm of raccoons. Eggs are passed in infected raccoon feces and can later become infective in the environment.
Can I see roundworm eggs in raccoon feces?
No. The eggs are microscopic and cannot be identified by looking at the droppings.
How do people become infected?
Infection occurs when infective eggs are accidentally swallowed from contaminated soil, hands, objects or other material.
What if raccoons are using my attic as a latrine?
The active raccoon problem, entry points and contaminated materials all need to be considered. For structural raccoon problems, review our Virginia Raccoon Removal & Control page or contact us.
