Down the Garden Path: Rabbit damage outdoors and controlling mice indoors

In a typical year, this column in the middle of December would focus on how to deal with wildlife damaging valuable landscape plants. This year, the ground is clear and lawns are still green. While the weather remains favorable, rabbits will feed on the diversity of plant material in the home landscape, lessening damage to any one plant. They will feed on grass, clover and other lawn weeds as long as they can. Rabbits also will continue to feed on plants well outside of the landscape, further limiting damage around the home.

However, that will change soon enough. It would be good to do a “walk about” your yard and scout for early feeding damage on your favorite plants or to identify any you hope to protect this winter. Rabbits, for example, turn to young twigs and branches of plants and tender bark on thin-barked trees. Examples are fruit trees, crabapples and burning bush for winter feeding. In the spring, emerging tender perennials make a great meal for rabbits.

What you can do to limit feeding

There are several methods that can be utilized to prevent feeding damage to valuable landscape plants. If you already see feeding damage, it is bound to continue and get worse. For rabbits, feeding damage can be prevented using chicken wire or a more specific type of fencing, often called rabbit fencing, which is designed to keep the younger rabbits from getting into your plantings. This fencing has the wire at a much smaller spacing near the bottom where a baby rabbit could get through. This is not so important in the winter but is great for next spring when offspring are feeding.

Field mice visitors

As we continue to enjoy the milder weather, so are field mice. Extension has gotten many calls, as would be expected, about mice in the home. These calls have not tapered off as they usually do, because the soil has not frozen, allowing the mice to continue to roam and forage for food. Not until we get a lot colder will the mice entering the home lessen. Often mice will get in the home by way of the garage if it attached to the house. Other points of access would be any openings as small as 3/8 inch in size. Check for failed caulk around plumbing pipe or electrical conduit on the outside of the home.

Don’t let them in

Weatherizing the home can be good for energy conservation and mouse management at the same time. Traps and baits can be effective in controlling the populations inside the home, yet as long as the weather remains moderate, others will take their place if those openings are not addressed. If you do find holes, pack them with steel wool.

Eliminating easy food sources inside the home also is a critical part of what needs to be done. Pet and bird food should be in metal containers with tightly sealed lids. Do not leave pet food in dishes overnight. Provide your pet with fresh food each day and clean the area after feeding. In the pantry and cupboards, vacuum up the crumbs. Do all you can to make your home uninviting and hope for some good cold weather.
