The answer to 'why do I have centipedes' is that centipedes are common household pests that seek out damp, dark environments to live and breed. They are attracted to moisture, rotting wood, and organic matter, often making their way into homes through cracks and crevices. Centipedes can be a nuisance because they can deliver a painful sting if threatened, and they may also prey on other insects in your home.
To get rid of centipedes, it's important to identify and eliminate the sources of moisture and organic matter that are attracting them. This may involve fixing leaks, improving ventilation, and removing any decaying wood or other debris around your home. You can also use insecticides or natural repellents to control centipede populations, but it's generally best to call a professional pest control technician if the infestation is severe or difficult to manage on your own.
