As most of you know it is prime time for birds to break in and clog your bathroom and dryer exhaust vents. It is important to know what type of birds you are dealing with though. Because most birds are protected and will require a permit to molest the nest. Bird removal from vents can be complicated if the bird is protected. The only birds that are not protected are the European Starling, the House Sparrow and the Pigeon (Rock Dove). For any other bird removal from vents you must obtain a permit from the US Fish and Wildlife service. It is very important to unclog these vents. Especially dryer vents as the nest is a fire hazard. Why not fix it this year you will again have the birds in vents.
How to Do Bird Removal From Vents
How to remove birds in vents. Be sure to get the birds in the vent out first. Normally by simply scarring them out. Then quickly shoving something temporary in until the permanent cover can be put on. Be sure to be weary of chicks as they may not be able to fly, sometimes it is best to let them grow up first, but when the nest is causing a fire hazard sometimes they have to go.
Then get all of the nest out of the vent by either pulling it out with a long hooked wire or blowing it out from the inside, be sure not to breath in the dust as it can be a health hazard. Sometimes the duct may need to be replaced if the birds busted it open. After the birds and the nest are removed put an approved cover over the vent so that the birds will never be able to get back in. On your dryer exhaust vent be careful of what cover you use as some will collect lint and clog.
