Excluding Wildlife From Sheds

Excluding Wildlife From Sheds

One of the most important ways to reduce conflicts with wildlife and vertebrate pests is to reduce the availability of their preferred living areas known as harborage. The concept is quite simple, if the

species can’t find a good place to live, it is less likely to remain in the area. At minimum, reduced living areas automatically reduces the number of animals that can live in an area. In some cases, good exclusion work can reduce unwanted animals to zero.

Sheds, particularly those that are low to the ground, provide excellent harborage for vertebrates. Excluding wildlife from sheds will go a long way in preventing skunks (Mephitis mephitis), cats (Felis cattus), woodchucks (Marmota monax), and other ground dwelling animals from taking up residence.

To exclude wildlife from sheds you have two options. Option 1, raise the shed up so that it is at least 6 inches off the ground (higher for larger sheds). The point is to make it more exposed to light and therefore less inviting as a place to take up residence. Certainly free-range cats can use it as an ambush site for native wildlife, so you have to keep that in mind.

Option 2 is to secure the foundation with screening or stone. I will discuss how to that in my next post.

With spring coming, birds, particularly cavity nesting birds are looking for places to nest, like in this bathroom exhaust vent pictured at the right. House sparrows (Passer domesticus) and Starlings (Sturnus vulgaris) are two invasive birds that like to nest in cavities like this bathroom exhaust vent. Don’t be deceived by the flapper valve as it often doesn’t stop birds from nesting.

I suggest securing the bathroom vents with an easy to install plastic vent cover available from your local hardware store. It is very inexpensive and won’t rust. Caution. DO NOT apply this advise to dryer vent exhausts. Those require a different approach due to the concern of lint build up that can cause a fire hazard.

Protect your bathroom exhaust vents now before the birds find it.

Garage Doors & Mice

Garage doors often have rubber edges that mice can damage. A new product is available that may help homeowners with this problem. It is easy to use.  Metal strips simply fasten over rubber edges (used to improve the insulation seal of the door) to prevent gnaw damage by mice.

I am not endorsing the product. Just letting people know about it. I would welcome hearing your comments.
