Application Method

Install screening over gable vents, ridge vents, and other attic ventilation to prevent wildlife entry while maintaining proper attic ventilation. Use 1/4 inch hardware cloth for rodents and squirrels, 1/8 inch for bats. Attach screening to interior or exterior of vent using screws, staples, or construction adhesive. For louver-style vents, install screen behind louvers on interior. For turbine vents, install screen collar at base. Ensure screening does not block air flow - attic ventilation is critical for moisture control and temperature regulation. Before installation, inspect attic to ensure no animals currently present. Gable vents are common entry points for squirrels, bats, and birds seeking attic nesting sites.

Timing

Install after confirming attic is unoccupied. Best done in fall before wildlife seeks winter shelter.

Frequency

One-time installation. Inspect annually for damage from weather or animal gnawing. Repair or replace damaged screening promptly.

Preparation Required

Inspect attic for wildlife presence. Measure vents to calculate screening needs. Purchase appropriate mesh size for target species. Have installation tools ready (tin snips, stapler or screws, drill).

Follow-up Required

Verify screening securely attached and properly covers vent. Ensure attic ventilation not compromised. Inspect screening quarterly for damage. Repair immediately if animals have gnawed through.

Safety Precautions

  • Work safely on ladder or in attic
  • Confirm no animals in attic before installing
  • Wear gloves when handling hardware cloth (sharp edges)
  • Ensure adequate attic ventilation maintained after screening
  • Do not completely seal vents - must allow air flow
