The answer to 'rat prevention tips' is to take proactive measures to make your home less attractive to rats and prevent them from entering in the first place. This includes sealing up any cracks or openings, removing food sources, and using repellents and traps if needed.
Start by inspecting the exterior of your home and sealing any gaps or holes larger than 1/4 inch where rats could potentially get inside. Use caulk, steel wool, or other durable materials to block access points. Pay close attention to areas around pipes, vents, and utility lines. Trim back trees and shrubs that could provide easy access to the roof or upper levels of your home.
