Might try use fishing line for a garden fence next year.

6. When I was

working as a bear vs humans capacity, we advocated for use of portable electric fences that are lightweight and run on a D cell battery. I have seen the sheep growers in my area use them to manage the sheep in isolated areas of their fields. We told hunters to use them for protecting themselves from bears while field dressing their kill.

And I know that you can place 18" long strands of fabric and that will act like a scarecrow and alert people that there is something there to not pass through, but you have to hang them every 18 - 20" apart... lasts longer than batteries. And if you already have your line up, just hang some reddish colored fabric on it,, that should work.
