I built a new home and moved in. After sometime I found out that a lot of birds were making nest in my vents all around my house.

Birds, commonly sparrow and starlings, may build nests in home vents. The birds will typically build nests near the vent opening, and then eggs will be laid in the nest. Once there are babies involved, it becomes more difficult to remove the nest material as you must wait until the babies leave. Without effective control, some birds are capable of causing serious damage to homes. Their droppings can stain and rot building materials as well as create unhealthy living conditions for residents.

Removal of Nests, Birds and Babies

Adult birds can be easily scared away or prodded from the vent. Once the adults are out, it is important to determine if there are babies inside the vent. Baby starlings do not leave the nest for several weeks after birth and are reliant on their parents for food and nourishment. It is critical that all birds be removed before securing the vent cover. Birds locked inside your vent will die, resulting in bad odour, maggots and flies.

Steps to remove the birds and their nests from the vents

Step 1

Wait for the babies to leave before removing the nest. Never remove a nest that has babies in it. You will know when they are gone as you will no longer hear their chirping. The babies should leave 11 to 15 days after being born.

Step 2

Remove the nest as soon as the babies leave before the birds have a chance to use the nest again or rebuild a new one. Open the vent and use a wire coat hanger to pull the nest out. Wear a mask over your mouth and latex gloves.

Step 3

Push out any excess portions of the nest using a hose. Push the hose through the vent until it reaches into the exterior of the house and the excess nest material is pushed out.

Step 4

Clean all around the area and vacuum out the entire area inside the vent where the nest was. Don't waste any time in cleaning the area since the bacteria left from the nest could be extremely hazardous.

Step 5

Monitor the vent to make sure the birds don't rebuild. Purchase a vent cover that is specific in keeping birds out.
