Opossum activity increases during mating season, often pushing them to seek shelter under homes, decks, and sheds. While they aren’t aggressive chewers, the damage they cause is primarily environmental and sanitary.

Common damage caused by opossums

  • Torn and compacted insulation in crawlspaces, reducing energy efficiency
  • Destroyed vapor barriers from nesting and movement
  • Contamination from urine and feces, creating health and odor issues
  • Damaged or displaced ducting and low-hanging utilities
  • Broken or bent foundation vents used for entry
  • Persistent foul odors that can enter the home

Why this damage matters
Opossum damage often goes unnoticed until odors, moisture problems, or higher energy bills appear. If left alone, a temporary shelter can turn into a long-term den, increasing cleanup and repair costs.

Bottom line
Early detection and professional exclusion during mating season can prevent expensive crawlspace damage and sanitation issues before they escalate.
