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 energiser, it forms a live perimeter around machinery like combines, sprayers, vintage vehicles, or seed stores, stopping rats, mice, pine-martens and raccoons before they chew a single wire.

How It Works?


This slowed down video shows a rodent making contact with both a positive and negative strip on the Rodent Shield barrier.

As soon as it bridges the two, it receives an electric shock demonstrating exactly how effective the system at protecting your equipment.

Rats are naturally neophobic, they don't like new things. They investigate slowly and once they receive a shock, it turns to both a psychological barrier as well as a physical barrier.

A Major Problem

Mild, Cold or Damp Climates all Encourages Nesting
Whether it's mild, cold or damp winters, it means rodents are active nearly year round.
This drives rodents indoors more frequently, especially into sheds, barns, and stored machinery and even campervans or RV's that are left idle for the winter.
Long-Term Machinery Storage Increases Risk
Equipment such as combine harvesters, balers, seed drills, sprayers, and recreational vehicles are often stored for six months or more during the off-season. These machines and vehicles contain insulated wiring, foam padding, and enclosed compartments — all highly attractive to nesting rodents.

Combine harvesters are particularly vulnerable due to their large, quiet internal spaces and complex electrical systems. Campervans and RVs face similar risks, as rodents are drawn to the warmth and shelter of upholstery, wiring runs, and stored food supplies.
Rats and mice can cause:
• Wiring loom damage, leading to electrical faults when the machine is restarted.
• Gnawed hydraulic hoses, coolant lines or plastic fittings.
• Blocked air intakes or exhaust systems due to nesting materials.
• Damage often goes unnoticed until peak season, resulting in costly downtime or repairs when time and parts are limited. Interior damage from droppings and urine, especially in stored RV's and Campervans

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.


Setup is a one-time task — after that, just remove the front panels to access your equipment and reattach them with ease.

Testimonials

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"

"I live on a heavily timbered 5 acres. I own an RV and I have to store it outside. I have been trapping and catching mice and rats in and under it for years.

However a few smart ones get past my gauntlet of traps and then they chew on my wiring harness and anything else they feel like. It's been a constant battle and very expensive. When I saw this system online I knew I had to have it.

I talked to Padraic and he explained every detail to me and within a week I had the system sitting on my front porch. It was super easy and fast to build and the best part is I haven't had a single mouse or rat get past it. Best money I ever spent! Highly recommend it."

"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.
