Securing the bottom of your deer fence is important for keeping out deer and pests that may try to dig underneath your fencing into your garden. For added security, we suggest purchasing these 18 inch rebar stakes. Rebar ground stakes work best in rocky soil conditions and on unusually hard terrain. These heavy duty fence stakes are made from hardened 3/8" rebar with a hook end for secure fastening to the ground. Place a metal fence stake every 5 feet along the bottom of your deer fence to prevent deer from crawling underneath your fence. Sold in packs of 20.
