Spring Safety Alert: Birds Nesting in Dryer Vents

As spring nesting season begins across San Antonio and the Hill Country, birds are increasingly building nests inside residential dryer vents located on the exterior of homes. These nests restrict airflow, trap lint and moisture, and can create a significant fire hazard inside the dryer exhaust system. Even after birds leave, the nesting material remains packed inside the vent, causing poor dryer performance, odors, and potential biological contamination inside the home. Blocked dryer vents are a known contributor to residential dryer fires due to overheating and combustible buildup. The recommended solution is professional dryer vent cleaning followed by installation of a properly designed exterior vent guard that prevents wildlife entry while allowing safe exhaust airflow.
