Bed bugs are small, parasitic insects that feed on human blood while they sleep, causing itchy welts and discomfort. To eliminate them, start by decluttering your living space to reduce hiding spots. Wash and dry all bedding and clothing on high heat to kill bed bugs and their eggs. Vacuum your mattress, carpets, and cracks in furniture, disposing of the vacuum bag or contents immediately. Consider using bed bug-proof mattress covers to trap any remaining insects. For more severe infestations, consult a pest control professional, as they can employ specialized treatments to eradicate these resilient pests effectively. Regular inspection and maintenance can help prevent future infestations.
