The answer to 'why do I have bed bugs' is that bed bugs are small insects that feed on human blood and can infest homes. Bed bugs are often brought into homes through luggage, furniture, or clothing from infested areas. Common signs of bed bugs include itchy bite marks, blood spots on bedding, and seeing the bugs themselves.
To get rid of bed bugs, it's best to call a professional pest control company. They can inspect your home, identify the extent of the infestation, and use specialized treatments to eliminate the bed bugs. DIY methods like vacuuming and washing bedding can help, but are unlikely to fully remove a serious bed bug problem on their own.
