The answer to 'why is my bed bug invasion' is that bed bugs are small, elusive insects that can infest homes and feed on human blood. Common causes of bed bug infestations include traveling and bringing them home in luggage, used furniture or clothing, and even visiting infested places. Symptoms include itchy bites, blood spots on sheets, and seeing the bugs themselves.
Bed bug infestations can be challenging to eliminate, and it's often best to call a professional pest control technician. DIY methods like using insecticides may only temporarily reduce the population, and improper treatment can cause the infestation to spread. A professional will thoroughly inspect, identify the extent of the problem, and develop an effective treatment plan using integrated pest management techniques.
