Their bites can cause itching and discomfort, leading to sleep disturbances and skin irritation.

If you suspect a bed bug infestation, it’s essential to act promptly. Contact a professional pest control service familiar with treating bed bugs to assess the situation and recommend an appropriate treatment plan. Early detection and intervention are key to preventing bed bugs from spreading throughout your home and becoming a larger problem.
