Dryer vents are a common place for starlings to build their nests. The telltale signs are bits of grass and debris sticking out of the exterior vent, chirping sounds, and sightings of birds coming and going from the vent opening. This is not only a fire hazard, but these birds also carry diseases and pests that can be harmful to your home. We make sure to effectively remove all debris left by birds and place a special covering over all vents to prevent them from returning to your house.
