Meet The Squirrelator
Well, it doesn’t eliminate them, but it does scare them off, and anyone who has ever grown mirlitons knows that squirrels eat the vine endings and steal the fruit. What to do? A wise old extension agent in Mississippi once said, “If there are 100 cures for something, probably none of them work.” I tried a 100 for squirrels: CDs, noise repellers, and cayenne on the bird seed (the cajun squirrels loved it). None of them worked. This motion-activated sprinkler shoots a short burst of water in an arc over your vine.
David Hubbell tested it for the last two years —complete with a game camera that he used to monitor it. The thing works. It is based on the simple principle: Did you ever see a squirrel dancing in the rain?
They work for other crops and will also keep your neighbors from pilfering your garden at night.

No one wants to nurse a mirliton for months through droughts, floods, and hurricanes, just to have Jack Frost arrive and kill all your flowers before they can fruit. Sprinklers are the most effective, simplest, and least expensive way to protect mirlitons from an early frost. Moreover, hot weather is the ideal time to set up your sprinkler and adjust it because you don’t want to be running around getting soaked in freezing weather.
Horticulturalists in the South seldom recommend sprinklers because most home gardeners grow soft-tissue vegetables that ripen long beroe the threat of fall frost. But we can find excellent advice from Canadian experts who have perfected the sprinkler systems to protect strawberries from early Sring frosts. We used their experience to design a simple and effective defense against temperatures down to 38 degrees in the fall.
Spraying water on a plant to warm it up seems counter-intuitive, but it works because of a simple principle; when water evaporates from the leaves, it transfers heat into the plant. And when changes to ice on the surface of a plant, it will add heat to that plant. Frankly, the science baffles me, but if you want to know more about it, click here for the Canadian study. For our purposes, the sprinkler frost-defense steps are simple:
Sprinkler Set Up:
1. Place a rotary sprinkler with a metal spike securely on the ground and connect a garden hose to it.
2. Turn the hose on and adjust the sprinkler and mount so that the stream covers the entire vine. Any sprinkler will do, but it’s best to use an impulse sprinkler that can spray a 180-degree arc so you can cover the entire vine. You may have to angle it up.
3. Secure the metal spike so that it does not move when the water is left on for several hours.
When and How to Use the Sprinkler system:
1. Watch the temperature forecast. If the temperature is predicted to go below 38 degrees that night, turn the sprinkler on at sunset and make sure it covers the entire vine.
2. Normally, the coldest part of the night is 4:00-6:00 a.m, so you can turn off the sprinkler after sunrise if the forecast is for temperatures above 40 degrees during the day.
That’s it. We have tested this system on mirlitons for over 10 years and every time it has worked and saved the vines. In 2012, Leo Jones in Harvey, Louisiana used the sprinkler for only part of his vine– it lived while the rest of the vine died (photo above). In 2019, Renee Lapelrolie also used sprinkler heads on only part of her vine, and again, only the protected portion survived (photo below). Not only can the sprinkler protect the vine in the fall, but during a mild winter, it can be used instead to keep the vine alive for a Spring crop.
Buying a sprinkler:
The Rain Bird impulse sprinkler is the best sprinkler head. You can buy it with the reinforced stake and it can cover a vine 40 feet long. There are other brands available, but the Rain Bird is the only one I have had experience with.
