Raccoons can cause a wide array of damage around a house due to their intelligence, curiosity, dexterity, and adaptability. Raccoon trapping is done with cage traps. Because of their size and strength, attic raccoons are usually removed with one-way entry/exit devices, then caught on the ground if need be.

Here’s a breakdown of the potential issues:

Structural Damage:

  1. Roof and Attic Access:
    • Shingles and Vent Damage: Raccoons can tear shingles to gain entry or use vents, chimneys, or soffits as entry points. This can lead to water damage if not fixed promptly.
    • Attic Insulation: Once inside, they can tear up insulation for nesting, reducing its effectiveness and potentially causing heat loss or gain.
  2. Chimney and Ductwork:
    • Raccoons might climb down chimneys, sometimes getting stuck or damaging caps, leading to potential fire hazards or pest entry.
  3. Crawl Space and Basement:
    • They might enter crawl spaces, damaging insulation, ducts, or electrical wiring.

Property Damage:

  1. Garden and Landscaping:
    • Plant Damage: Raccoons dig for insects or grubs, turning over plants, flowers, or vegetables.
    • Pond and Fish: They are notorious for raiding garden ponds, eating fish or frogs.
  2. Outdoor Structures:
    • Decks, Sheds: They can burrow under or inside these structures, potentially causing structural weakening or making a mess.

Health and Hygiene Issues:

  1. Disease Transmission:
    • Raccoons can carry diseases like rabies, roundworm (Baylisascaris procyonis), distemper, and parasites like ticks and fleas.
  2. Waste and Smell:
    • Feces and Urine: Raccoons can leave droppings and urine in attics or other areas, leading to bad odors, potential health hazards, and damage from urine soaking into wood or drywall.
  3. Food Contamination:
    • If they access trash or compost, they can spread garbage, attracting other pests and creating a mess.

Additional Concerns:

  • Electrical Damage: Raccoons might chew on wires, leading to short circuits, potential fires, or electrical malfunctions.
  • Water Damage: By accessing areas like roofs improperly, they can cause leaks or exacerbate existing ones.
  • Noise: Raccoons are nocturnal, and their activity in walls, attics, or other parts of the house can be disruptive, especially at night.

To mitigate raccoon damage:

  • Secure Entry Points: Use raccoon-proof caps for chimneys, secure vents, and seal all possible entry points.
  • Manage Attractants: Secure trash cans, remove pet food, and protect garden areas.
  • Deterrence: Use motion-activated lights or sprinklers, though these are not foolproof.
  • Professional Help: For serious infestations or damage, wildlife removal experts can trap and relocate raccoons while repairing damage.

Remember, while raccoons are smart and adaptable, humane methods are best for dealing with wildlife conflicts to ensure both the health of the animals and the integrity of your property.
