Rat proofing and prevention is the humane way to deal with this rodent to prevent it from coming in to begin with! Airbrick mesh covers made from stainless steel mesh provide a physical barrier which it’s very difficult if not impossible to chew through. Various sealants can be applied to stop them gaining access. Electronic repeller’s are also an effective way of deterring rodents. They work by disrupting the rodents behaviour to try and force them out and stay out. If a prevalent problem exists they residing rats would have to be destroyed first before repeller’s can be used effectively to prevent further issues.
