Two hot wires for raccoons
A raccoon climbs anything you can build, so stop building up. Sweet corn is a ten-day emergency, not a season-long one.
What it is
Two electrified wires at roughly 6 and 12 inches above the ground, outside the garden fence, energized only during the window when there's something worth stealing.
The numbers
- 6 in and 12 in above ground. A raccoon's path is along the ground and up — these catch it at the start.
- Sweet corn is vulnerable at the milk stage, which is about a three-to-ten-day window. Energize for that, then take it down.
- Height does not work: a raccoon climbs a 6-ft fence as easily as a 2-ft one.
- They also work latches — anything a person can open with one simple motion, a raccoon can open.
Why it's here
Because the damage signature is unmistakable and the solution is seasonal. Stalks pushed flat, husks peeled back like somebody did it by hand, cobs gnawed down one side and dropped — that's a raccoon, and no amount of fence height will stop it. Two wires and ten days will.
The automation angle
A camera settles who it is in one night — people routinely build a $900 deer fence against a raccoon. A fence-voltage monitor on the far end tells you the wire is actually hot, which matters most on the nights you're not checking.
The catch
An electric fence that isn't hot is a clothesline. Check the voltage, keep the line clear of wet grass that drains it, and ground it properly — poor grounding is the usual reason a charger 'doesn't work'. And keep the bottom wire's path mowed, or you'll be running a fence that shorts out every time it rains.
