The answer to 'how to kill rodent' is to use a combination of traps, baits, and exclusion methods to effectively eliminate rodents from your home. Traps are one of the most common and effective ways to get rid of rodents, as they physically remove the animal from your home. Baits containing rodenticides can also be used, but should be placed carefully and out of reach of children and pets. Additionally, sealing up any entry points and removing food sources will make your home less attractive to rodents.
It's important to take precautions when dealing with rodents, as they can carry diseases. Wear gloves and avoid direct contact with the animals or their droppings. Dispose of any dead rodents properly. If the infestation is severe or you're uncomfortable handling the problem yourself, it's best to call in a professional pest control technician.
