The answer to 'why is my rat bites' is that you likely have a rat infestation in your home. Rats are known to bite humans, especially if they feel threatened or are trying to protect their young. Common symptoms of rat bites include puncture wounds, swelling, redness, and pain at the bite site. Rat bites can also become infected if not properly treated.
Rats are attracted to homes that provide easy access to food, water, and shelter. They may enter through cracks, holes, or openings in your home's exterior. To prevent and address a rat infestation, it's important to seal up any entry points, remove food sources, and use traps or baits to eliminate the rats. If the infestation is severe or you are unable to effectively control the rats on your own, it's best to call a professional pest control technician who can safely and effectively remove the rats and prevent future infestations.
