Why Waverly Kitchens Are Prone to Drain Fly Infestations
Waverly’s historic row homes many built in the early 1900s often have aging plumbing systems that contribute to drain fly problems. The combination of old cast iron pipes Baltimore’s high humidity and the area’s clay-heavy soil creates conditions where organic buildup thrives.
