This is a 3-year follow-up to my July 1 and July 9 posts from 2010, where I described a simple “fishing line” deer fence I made with five runs of monofilament line that proved a failure. But I liked its low cost and low visibility and was determined to tweak the original design to have a fence that would keep out deer, rabbits, and groundhogs.
I stretched 3-ft. wide chicken wire along the base to provide protection from rabbits and groundhogs (those rascals will chew through the black propylene “deer netting”). The bottom of the chicken wire is buried about 6-in. down in the soil. I replaced the horizontal runs of fishing line with runs of 14-gauge wire spaced 12-in. to 18-in. apart, from the top of the chicken wire to the top of the fence (around 7-ft.). Then I wrapped fishing line (20# test) from the lowest wire to the top wire in a somewhat random pattern. The fishing line has broken in places (mostly due to me hitting it with tools) but is easy to repair.
We have a fairly high deer population in my area and my fence is barely 7 ft. in places. I’ve gone through 3 complete years with no deer, rabbit, or groundhog getting in. The fishing line is pale green and I doubt they see it. Maybe they bump into it and get spooked? I have 6-in. diameter wood posts at the corners (10 ft. tall with 2 ft. in the ground) and some 8-ft. metal T-posts between. I use in-line strainers to maintain tension in the horizontal wires. It is fairly unobtrusive.
