Coyote Update

At last week's Bel~Air Association Annual Meeting, we discussed our community's Coyote problem and actions one could take to better protect their home, pets and family. Below is FENCING information from the Washington Department of Fish & Wildlife. [Note that the Bel~Air Association is not making any endorsements -- especially as to the potential liability associated with an electrified fence!]

Build a coyote-proof fence. Coyotes don’t leap fences in a single bound but, like domestic dogs, they grip the top with their front paws and kick themselves upward and over with the back legs. Their tendency to climb will depend on the individual animal and its motivation. A 5-foot woven-wire fence with extenders facing outward at the top of each post should prevent coyotes from climbing over (Fig. 6).

However, all coyotes are excellent diggers, and an effective fence needs to extend at least 8 inches below the surface, or have a galvanized-wire apron that extends out from the fence at least 15 inches (Fig. 6).

Fence extensions.Figure 6. Fence extensions are required to keep coyotes from jumping over a 5-foot fence. Angle the top of a woven-wire fence out about 15 inches and completely around the fence. An effective fence extends below the surface, or has a wire apron in front of it to prevent digging.
Six-foot electric fence.

Figure 8. Two electrified wires, 8 and 15 inches above ground and offset from an existing wood fence by 12 inches will prevent coyotes from accessing the fence. A single strand may be sufficient, but two electrified wires will provide added insurance.

Electric fences can also keep coyotes out of an enclosed area (Figs. 7 and 8). Such a fence doesn’t need to be as high as a woven-wire fence because a coyote’s first instinct will be to pass through the wires instead of jumping over them. Digging under electric fences usually doesn’t occur if the bottom wire is electrified.

Alternatively, install a commercial device, such as the Coyote Roller™ , to prevent coyotes from being able to get the foothold necessary to hoist them over a fence (Fig. 9). [CLICK HERE for more information from one Southern California supplier of COYOTE ROLLERS.]

Enclose poultry (chickens, ducks, and turkeys) in a secure outdoor pen and house. Coyotes will eat poultry and their eggs if they can get to them. Note: Other killers of poultry include foxes, skunks, raccoons, feral cats, dogs, bobcats, opossums, weasels, hawks, and owls.

To prevent coyotes from accessing birds in their night roosts, equip poultry houses with well-fitted doors and secure locking mechanisms. To prevent them from trying to go under the fence, stake the bottom of the fence flush to the ground, or line the bottom of the fence with bricks, fence posts, or similar items. For ways to prevent coyotes from digging under a fence or structure see Figure 10.

To prevent coyotes and other animals from accessing poultry during the day, completely enclose outdoor pens with 1-inch chicken wire placed over a sturdy wooden framework.

Figure 10. Various ways to install a barrier to prevent coyotes from digging under chicken coops and similar places. To add to the life of the barrier, spray on two coats of rustproof paint before installation. Always check for utility lines before digging in an area. (Drawings by Jenifer Rees.)

a. Lay large flat stones, concrete patio pavers, or 1/4-inch hardware cloth (held in place with stakes) on the surface of the soil next to a wall. The barrier forces coyotes to begin digging farther out and they will most likely give up in the process.b. Bend hardware cloth into an “L” shape and lay it in a trench so that the wire goes at least 1 foot below ground and 1 foot out from the wall.c. Excavate a 3 x 3 inch trench along the side of a wall, and hammer 2-foot lengths of 1/2-inch rebar, spaced a few inches apart, into the ground. Cover the tops with concrete or dirt.

Valuable information! Looking forward to seeing your notes posted.

This won't succeed in reality, that is exactly what I think.
