Buying a home is one of the biggest investments most people make, and while buyers often focus on location, pricing, financing, and cosmetic details, pest prevention is sometimes overlooked during the process. Hidden pest activity can lead to unexpected repairs, structural concerns, sanitation issues, and additional maintenance costs after closing.
In Washington DC, climate conditions, seasonal pest pressure, aging structures, and urban environments make pest awareness an important part of responsible home purchasing. A thorough evaluation before completing a purchase can help identify concerns early and reduce future surprises.
At EJ’s Pest Control, prevention starts with understanding property conditions before moving into a new home.
