Start at the roofline
Coves, roof-to-wall transitions, eaves, soffits and tile edges can leave small openings that are difficult to see from the ground.
Check vents and bonnets
Damaged screens or unprotected roof vents can create a direct path into attic space while still needing to remain properly ventilated.
Look beyond the roof
Trees touching the house, utility penetrations and garage-to-attic connections can also help rodents reach the attic.
