Raccoon Attic Cleanup: Smell Not Deadly, Roundworm Eggs Are the Real Risk

Neighbor had raccoon in attic; told they must gut entire house to remove smell/droppings or house is "forever marked," and smell causes death if inhaled over time.

Fact Check

• Smell is not toxic—no research supports this claim
• Raccoon roundworm (Baylisascaris procyonis) eggs in dried feces can become airborne; dangerous if inhaled/swallowed
• "Marking" is irrelevant—raccoons invade homes with no prior raccoon history
• Proper cleanup (PPE, HEPA vacuum, disinfection) eliminates risk without gutting

Recommendation

Neighbor should read ICWDM literature on raccoon roundworm and hiring professionals before signing contracts. Excessive threat claims warrant skepticism.
