Rat Hunt on the Farm: A Thermal Imaging Mission

On nights, gusts of wind rattle the metal sheets of the barn. Squatting beside hay bales, Allen flicks on his flashlight and spots streaks of dark shadows along the wall base. When the weather gets warm, rats flee from farm fields and settle down around the farm. These omnivorous pests feast on scattered grains and leftover feed scraps. Worse still, they spoil massive amounts of grain, gnaw through power cables and leave excrement all over sacks, becoming a real hassle for farm dwellers. To tackle the rampant rodent problem efficiently, Allen turns to thermal imaging devices, which serve as his core gear for night pest control.

"Once the weather gets colder, swarms of rats will flock to the central area of the barn." Late summer and early autumn are the peak seasons for rat incursions into farms. Allen once used poison baits, yet he abandoned this method for fear that farm poultry might accidentally eat them. Later, he adopted air guns equipped with infrared night vision scopes. Such equipment has become more affordable in recent years while delivering greatly upgraded performance.

"The biggest advantage of heat imaging is that visible light is never a necessity," explained a veteran rodent hunter in an interview. "It adopts invisible infrared fill light that can never be perceived by humans or animals, just like holding an invisible flashlight in the dark." Allen uses the NNPO SPEAR, which costs less than 1,500 US dollars and is fitted with laser rangefinder and ballistic calculation functions. "Aiming feels much like playing video games, yet caution is always needed," Allen joked. He once lay in ambush aiming for a long time, ending up with sore limbs and even tripping over his own feet while standing up.

Amusing mishaps aside, he had no time to amuse himself that night, keeping working nonstop with his modified air gun and SP-645L device. "This device supports seven pseudo-color display modes: White Hot, Black Hot, Red Hot, Green Hot, Fusion, Iron Red and Desert Yellow. I can instantly figure out the activity routes of rats with a quick glance."

Allen follows a fixed routine: he first patrols the surroundings with portable infrared camera to pinpoint rat hotspots, then places a small stool and sets up a tripod to wait for targets to show up. Most targets stay 15 to 20 meters away. He switches to low magnification for a broader field of view, and swiftly adjusts the magnification to 4 to 8 times once rats appear. Powered by mature thermal imaging technology, the device can capture every tiny detail including the fur of rats, making accurate shooting almost guaranteed.

Allen also shared a practical rodent-hunting tip: "A qualified headlamp is absolutely indispensable." He noted that ordinary flashlights are far from enough when picking up dead rats in the dim barn. So are you fully prepared for your spring rodent shooting work?
