The answer to 'bed bug swarms' is that bed bug infestations can sometimes appear as 'swarms' or clusters of the insects, especially in severe cases. Bed bugs are small, flat insects that typically hide in cracks and crevices during the day and come out at night to feed on human blood. Seeing a large number of bed bugs at once is a clear sign of a significant infestation that requires professional treatment.
Common causes of bed bug swarms include poor sanitation, clutter, and lack of regular pest control. Symptoms include itchy bites, blood spots on sheets, and seeing the insects themselves. While some DIY treatments like vacuuming and using heat or chemical sprays can help, a severe bed bug infestation is best handled by a licensed pest control professional who can fully eliminate the problem.
