Does the Fishing Line Fence Work for Deer?

The question of whether or not a fishing line fence is effective for keeping deer away from gardens and other areas has been debated for some time. The idea behind the fishing line fence is that it creates an invisible barrier that deer will be afraid to cross. It’s a low-cost solution that can be easily set up by homeowners who want to protect their property from hungry wildlife.

The concept of a fishing line fence is simple: strands of strong, lightweight monofilament fishing line are stretched between posts and supported by wire ties, creating an “invisible” fence. The theory is that when the deer walk up to it, they’ll feel the tension of the line and be scared away. Some proponents also suggest adding flags or reflective tape to make the barrier more visible and intimidating.

But does it really work? Unfortunately, there’s no definitive answer — opinions seem to vary depending on who you ask.

Some gardeners swear by the effectiveness of this method, claiming that it keeps deer out of their gardens year after year without fail. Others say they’ve tried it without success — either because the deer weren’t intimidated by the invisible barrier or because they figured out how to jump over it or go around it.

One thing that experts do agree on is that a fishing line fence is not a foolproof solution for deterring deer — other methods may be needed in combination with this one for best results. For instance, some people combine a fishing line fence with repellents or motion-activated sprinklers to create an even more effective deterrent.


In short, whether or not a fishing line fence works for keeping deer away depends on many factors, including how determined the animals are and how well you set up your system. While it may not guarantee success, this low-cost solution could still be worth trying if you’re looking for an easy way to keep deer out of your garden.
