A couple of years ago, i pushed 10-foot tall rebar poles into the ground beside my fence posts. Then i strung nylon twine between these tall, but slender, "fenceposts."
For the gate, i had the building supply store bend a 20-foot piece of rebar into a big upside-down U, 8 feet tall on each side and 4 feet wide at the top. Not until the second summer did the deer figure out that they could jump over the gate (and under the rebar) and munch their midnight snack in the garden.
What to do? I cut a shiny old Christmas garland into sections and hung them from the top of the rebar |¯|.
How do we keep our mental, verbal, and behavioral pests at bay? Mindfulness is our first and strongest deterrent.
First, we have to get to know that pesky thought, that nettlesome rejoinder, or that vexing action. Notice how the body feels just after your particular "pest" has appeared. No need to judge yourself; what's done is done. We are on the hunt, so we have to be stealthy--alert and calm.
When we finally see how our particular pest gains entry, then we will know how to strengthen our defenses. It may be something as fun and flowing as an old Christmas tree garland.
