What is the Rodent Shield?

From the makers of Cheetah Electronics Ltd.
A trusted, family-run Irish business with over 50 years of experience manufacturing electric fencing for the agricultural sector, now bringing that same expertise to rodent protection.

Rodent Shield is a modular electric barrier system designed to protect valuable equipment from rodent damage.

Built from upright, smooth-surfaced barriers and powered by a 5-joule energizer, it forms a live perimeter around machinery like combines, sprayers, vintage vehicles, or seed stores, stopping rats before they chew a single wire.

A Big Problem on Farms

Mild, Damp Climate Encourages Nesting
Relatively mild winters mean rodents are active nearly year round.
This drives rodents indoors more frequently, especially into sheds, barns, and stored machinery.

Long-Term Machinery Storage Increases Risk
Equipment like combine harvesters, balers, seed drills, and sprayers are often stored idle for 6+ months, especially over winter. These machines contain insulated wiring, foam padding, and enclosed compartments, all attractive to nesting rodents. Combine harvesters are particularly vulnerable due to large, quiet internal spaces and complex electrical systems.

Rats and mice can cause:
• Wiring loom damage, leading to electrical faults when the machine is restarted.
• Gnawed hydraulic hoses or coolant lines.
• Blocked air intakes or exhaust systems due to nesting materials.
• Damage often goes unnoticed until peak season, leading to critical failures during harvest or sowing, when time and spare parts are limited.

Why is the Rodent Shield Better?

Built by Experts in Electric Fencing

Cheetah Electronics has decades of experience designing robust, farm-grade energisers for livestock.

This system draws on that expertise to create a rodent specific energiser calibrated for low height.

Modular, Scalable Protection

Each 25cm-tall interlocking panel connects together seamlessly to create a custom sized barrier, tool free!

Whether you’re shielding a combine harvester, a seed drill, or a grain vacuum, you can build a complete perimeter.

How It Works

Innovative Barrier

Unlike cattle fencing, this system uses patented technology & patterns with alternating positive and negative tracks.

Designed to exploit rodents’ natural sensitivity to electric fields and disrupt approach behavior.

Quick Setup Time

It is recommended to setup up each barrier individually first. It takes roughly a minute to setup each one meter barrier. Once all they are complete you can put them down and start to assemble the perimeter.

-

It takes 30mins +/- to complete the perimeter of a combine harvester. Once fully connected the energiser can be attached to power up your shield.

Real feedback from real people

"It has taken the worry out of the rodents getting into the combine. It is a big worry with some many electronics in them, you could run into serious money if you have a problem.It's simple to use and if you want to move the combine out you just have to remove 4 screws. I opted for this because poison and traps will only stop so many pests, not them all"

"To me the shield is more of an assurance that you won't have mice, the last few year I use to have chafing underneath the combine. This year after the system was in place I haven't seen any signs of it. It's simple to use, in between harvests we just unscrew and move the front of it and take the combine out. I don't use poison but I do use traps inside and outside of the shield. During bad weather I might catch 1 a week outside the shield but there hasn't been any inside the shield."

John was an initial adopter of our Version 1 prototype. Thanks to John we have been able to fast track the development of the shield. When asked for a comment on what he thought of the Shield he said; "The rodent shield is great, the system definitely deters rats & mice. I had constant issues with rodents around the machine. It is a lot more effective for me as the traps did little but the shield has stopped every mouse that has went near it."

Hugh has also helped with our development journey. With Hughs system we wanted to try and test as many different variations of the shield. Laying the PCB flat to standing it up, what pattern would be most effective, how many shocks would we need per minute etc. Another key here was the use of wildlife cameras to see what areas of the system needed development. It was the perfect testing ground and has got us where we are today.

George was also a very early adopter with this system. Over the past 2 years plenty of R&D has happened here. George stored plenty of other things around this shed so there is always going to be rodents hanging around. It was a great place to test the capabilities of the system and gave a solid foundation of information to build on.
