To rodent-proof, you will need to close off all the points of access that you identified. Use rodent exclusion materials like heavy-gauge wire screening to cover holes, metal mesh to stuff into holes around pipes, and expanding foam sealant to spray overtop of metal mesh and fill other gaps and cracks.
Rodent proofing a home is the only way to ensure that your home will be permanently protected from future rodent infestation. Best of all, rodent proofing can be done without any dangerous chemicals or traps. How does it work? The rodent proofing process is done in 3 phases:
Phase 1: Inspection – Every rodent proofing job will start with inspection of your attic for rodent entry access points. Rodent infestation is only possible when these holes and gaps are left unsealed.
Phase 2: Sealing – After identifying all possible rodent access points, these entry ways are sealed with professional grade sealant and steel mesh, denying access to new rodents and preventing infestation.
Phase 3: Cleanup – Once all the entry points are sealed your attic is cleaned, disinfected and deodorized.
