Calling All Aussies & Kiwis
The Sound Behind the Silence
Krovium™ uses special RoomGuard technology with ultrasonic sound waves — frequencies you and your pets can't hear, but pests can. Their sharper hearing makes these waves uncomfortable, helping drive them away from your home.
The device continuously cycles through 25–65kHz ultrasonic frequencies, preventing pests from easily adapting or getting used to the sound. Simply keep it plugged in and let it work around the clock to help deter mice, those scary redback and huntsman spiders, bedbugs, cockroaches, and many other unwanted pests.
No Poison, No Noise, No Hassle
There's no poison, no bait, and nothing toxic sitting around your home for kids or curious pets to find. That also means no suffering, no dead body stuck somewhere in a wall or roof cavity, and no mess for you to clean up after. There's also no risk of a pet or local wildlife eating something that's already been poisoned — a risk most people don't think about until it happens. It's a gentler way to deal with the problem — for your family, and for the pests too.

Surprised how well it worked
Was honestly surprised how well this worked. There’s always bugs crawling around my apartment. I put one in my bedroom and one in my kitchen three weeks ago and I swear I haven’t seen a single bug in the last week! Took about two weeks but they’re gone. My dog is itching less, I’m not waking up with mosquito bites anymore…. will be purchasing the six pack for my parents home now!!

No more creepy crawlies!
Living on a fixed retirement income meant I needed to be careful about expenses, but after battling mice for months with cheap store traps, I finally ordered these Krovium pest repellers. Should have done it sooner! With my arthritis, I couldn't keep bending down to set traps. The Krovium system was completely hands-off, just plug in and forget. The price was actually reasonable. Haven't seen a single rodent in five months. Old dog can learn new tricks, should've tried this first!

Effective pest repeller
I decided to try the Krovium™ RoomGuard Pest Repeller, and it has been a great addition to my home. It was quick to plug in and started working right away. Over the next few days, I noticed fewer unwanted pests around the house. I also like that it’s odor-free, chemical-free, and safe to use around my family and pets. It’s an easy, low-maintenance solution, and I’m happy with the results so far.
The Room-by-Room Method
Here's the part most people get wrong: they buy one RoomGuard, plug it into the hallway, and expect it to cover the whole house. It won't — and that's not a flaw, it's just how coverage works. One device is built to handle one room. So instead of one unit doing an impossible job, you place a RoomGuard in each room where you've noticed activity, near the skirting boards, where they travel. It's the difference between a device set up properly and one that was never going to work in the first place.
Included free: Your Guide to Success
Most of these things end up in a drawer within a month — not because they're junk, but because everyone makes the same mistake: one unit in the hallway, expected to cover the whole house. Like one lamp lighting every room. Nobody tells you that up front, so you blame the product instead of the setup.
That's why your order includes this FREE guide we wish came in every box: the 7-step Room-by-Room Method, a placement diagram, a 14-night tracking log, and straight answers for week one. Valued at $19.99.

Every "Yeah, but ..." Answered
Does it actually work, or is this just flashing lights?
Does it actually work, or is this just flashing lights?
Ultrasonic sound isn't a myth — it's a real technology used in pest control for years. What trips most people up isn't whether it works, it's how they use it. Ultrasound stops the moment it hits a wall. One unit in the hallway was never going to cover a four-bedroom house. Our solutions is built around covering your home room by room, so the ultrasonic waves actually reaches where the problem is.
Won't they just get used to it after a while?
Won't they just get used to it after a while?
Our RoomGuard technology uses ultrasonic frequencies rather than one constant tone, so pests don't settle into it the way they can with a single repeating frequency.
How do I know it's actually doing anything?
How do I know it's actually doing anything?
There's a light on the unit that shows it's active, so you always know it's running. Beyond that, the honest answer is: with any pest solution, the real proof is a quieter roof and no more mess to clean up — not a countdown timer.
Is it safe for my pets and kids?
Is it safe for my pets and kids?
Yes. The Krovium™ RoomGuard uses ultrasonic sound, not chemicals, sprays, or bait. There's nothing toxic anywhere near your family — pets included.
What pests does it actually work on?
What pests does it actually work on?
Our RoomGuard pest repeller is designed to get rid of a wide range of pests, including rats, cockroaches, bedbugs, mosquitoes, spiders, fleas, flies, ants, crickets and many more.
How many do I need for my house?
How many do I need for my house?
Because ultrasonic waves don't pass through walls, we recommend one unit per room where you're hearing or seeing activity. Most homes with a roof or subfloor problem see the best results running a few units at once.
How is this different from the cheap ones at stores like Bunnings?
How is this different from the cheap ones at stores like Bunnings?
A lot of ultrasonic devices on the market are sold as a single unit expected to cover an entire house — which is exactly why so many people say they didn't work. Ours is built and sold around the room-by-room approach, because that's what the evidence actually supports.
How much does it cost to run?
How much does it cost to run?
The Krovium™ RoomGuard sips electricity, so realistically mere cents per week running continuously.
What if it doesn't work for me?
