Repellio is easy to live with: plug it in close to where pests get in and leave it on. Give it the few weeks the brand describes while you also seal gaps, store food tightly and trap any mice you see, and you'll know whether it earns a place in your home. Start with one unit or the 3-pack, keep spare units boxed until you're sure, and order from the official store.
- Best for
- Small spaces and single problem rooms, like a dorm, an apartment kitchen or a garage, where you want a chemical-free unit you can plug in and move around.
- Why we like it
- A modest, honest-sounding 120 sq ft rating per device, nothing to refill, and packs that bring the price down to $20 a device.
- Keep in mind
- Published tests of plug-in sound repellers are mostly negative, the brand's own chart talks about 3 to 4 weeks, and change-of-mind returns need the device unused.
- 30-day returns (change-of-mind returns must be unused)
- Ships from the official store

What is Repellio Ultrasonic Pest Repeller, and who makes it?
Repellio is a compact, egg-shaped pest repeller that plugs straight into a wall outlet. The brand says it pairs three kinds of waves, bionic, electromagnetic and ultrasonic, to make a space uncomfortable for mice, rats, cockroaches, ants, mosquitoes, spiders and other common pests, so they move out instead of dying inside your walls.
Each device is rated by the brand for up to 120 sq ft, roughly one room, and there's nothing to refill or recharge. It's sold through the brand's own online store as a single unit or in packs of 3, 5 and 10, which makes it simple to put one in the kitchen, one in the garage and one wherever else you've seen activity.
It's sold by Norvello Limited (Manchester, United Kingdom). The terms linked from the Repellio checkout name Norvello Limited as the operator of ShopperZelo, the store that takes the orders; the brand site's own terms say the seller is the company named at checkout. Customer care runs through a US phone line and support@get-repellio.com. Returns go only to the address support sends with your return authorization, never to the company's office.
Who Repellio suits, and who should skip it
A good fit for
- Apartment dwellers, students and renters who want to protect one or two rooms without sprays
- Families with young children or pets who'd rather avoid poison baits and chemical sprays
- People who prefer a humane approach that drives pests away rather than killing them
- Anyone who likes a portable fix they can unplug and move to wherever the problem shows up
Skip it or ask a doctor first
- Large open-plan homes counting on one unit. The brand's own rating is 120 sq ft per device.
- Homes with pet rodents, such as hamsters, gerbils or guinea pigs, in the same room, since the sound targets rodents
- A serious infestation that needs fast results. Even the brand's chart talks about 3 to 4 weeks, so pair it with traps and sealing or call a professional.
Features and materials
| Technology | "Triple soundwave technology": bionic, electromagnetic and ultrasonic waves, according to the brand. Frequencies and output power aren't published. |
|---|---|
| Coverage | Up to 120 sq ft per device, according to the brand, which says larger spaces may need several units. |
| Power | Plugs into a standard wall outlet. No refills or recharging. Voltage and wattage aren't published. |
| Design | Compact, egg-shaped white body with a blue light strip along one side, as shown in the brand's photos. The brand calls it lightweight and portable: unplug it and move it to another room. |
| Targets | Mice, rats, cockroaches, ants, mosquitoes, spiders, flies and termites, according to the brand's FAQ. It repels rather than kills, so there's nothing to clean up afterward. |
| Timeline | The FAQ says most pests begin leaving within 48 hours, with full results after a few days. A chart on the same page describes a longer process: pests still active at 3 to 5 days, a significant decline at 2 weeks and none left at 3 to 4 weeks. |
| Safety | Chemical-free, with waves the brand says people and pets can't hear. |
| In the box | The store doesn't list the box contents or the plug type. |
Repellio versus sprays, by the brand's own count
The sales page lines Repellio up against chemical sprays. These are the brand's claims, without the spray column.
- Chemical-free. No sprays, baits, odors or residue, according to the brand.
- Works around the clock. It keeps running for as long as it's plugged in.
- Family and pet friendly. The brand says people and pets can't hear its waves.
- Humane. It repels pests instead of killing them, so there are no dead pests to clean up.
- Room-sized coverage. Up to 120 sq ft per device, according to the brand.
These are the brand's claims. We found no independent test of Repellio itself.
Does Repellio Ultrasonic Pest Repeller work?
The brand's explanation is that Repellio's three wave types, bionic, electromagnetic and ultrasonic, disrupt pests' nervous systems and create surroundings they won't tolerate, while staying inaudible to people and pets. On the timing, its FAQ says most pests begin leaving within 48 hours, and a chart further down the page lays out a slower path: still active at 3 to 5 days, a significant decline by 2 weeks and none left by 3 to 4 weeks. That same chart advises installing the unit as close to the pest problem as possible.
Outside the brand's own pages, the research on store-bought sound repellers mostly comes up short. A University of Arizona Cooperative Extension review of the published tests found that commercial sonic devices haven't been shown to work in homes. Bed bugs gathered near ultrasonic devices as often as near silent controls, cockroaches walked into treated and untreated rooms in equal numbers, and rats and mice showed only a mild dislike that faded as they got used to the sound. For mosquitoes, a Cochrane review of 10 field studies found electronic repellers didn't reduce bites at all.
There are a few points on the other side. A 2023 laboratory study found German cockroaches avoided certain ultrasonic frequencies, especially 35 and 40 kHz, in a controlled chamber, and the authors of the older rodent study suggested that well-placed devices may help repel pests. UC IPM explains why placement matters so much: ultrasound is directional, doesn't penetrate behind objects and loses strength quickly with distance. Repellio's modest 120 sq ft rating fits that physics better than whole-house promises do.
So set it up the way the evidence suggests. Plug it in near where pests enter or gather, such as under the sink, beside the pantry or by the garage door, with open space in front of it. Use one per room and give it the 3 to 4 weeks the brand describes. In the meantime, do the things pest experts rely on: seal openings wider than about 1/4 inch, keep food sealed, clear clutter where pests hide, and set traps if mice are already inside. Keep in mind that the EPA doesn't register repellers like this or review their effectiveness data before they're sold.

How the refund really works
You can return Repellio within 30 days of receiving your order. Damaged, defective or wrong items are refunded or replaced; send photos with your request. If you simply changed your mind, the device must be unused, undamaged and in its original packaging with everything that came with it. Contact support first: they review the request within about 3 business days and send a return authorization form plus the return address. Ship it there, email them the tracking number, and allow up to 7 days for inspection and 3 to 5 business days for the refund to reach your card. Return shipping is on you, and the original shipping fee isn't refunded.
Before you pay: The store's terms include a general section on subscriptions, but the Repellio checkout we saw sold one-time packs only. After you pay, the store moves on to a page with extra offers; you only pay for what you choose to add.
Is Repellio Ultrasonic Pest Repeller legit or a scam?
Repellio is a real product sold through its own store. Orders go through ShopperZelo, run by Norvello Limited in the UK, with a US phone line, email support, tracked shipping and a 30-day return policy. The store says orders are usually processed within 24 hours and reach US addresses in 2 to 12 business days.
The store's domain doesn't have a Trustpilot page, so we don't show a buyer rating here. Two habits make ordering easy: the checkout opens with the 3-pack selected and may show an extended warranty at $5.99 per device, so check the quantity, the add-ons and the total before you pay. After payment, extra offers appear on the next page, and you only pay for what you choose to add.
Plan for the return rules too. Change-of-mind returns need the device unused and in its packaging, so if you buy a pack, test one unit and keep the rest sealed. If anything arrives damaged, send photos to support within 48 hours of delivery.
Where to buy the original Repellio Ultrasonic Pest Repeller
Order from the official Repellio store. That's where the pack prices, the US support line and the 30-day return policy apply.
Plug-in repellers that look a lot like Repellio are sold under other names and in generic multi-packs, so starting from the official store is the surest way to get Repellio itself and its support.

Repellio Ultrasonic Pest Repeller FAQ
Does Repellio really work?
The brand says its bionic, electromagnetic and ultrasonic waves drive pests out, with full results in a few days to about 3 to 4 weeks. Independent tests of plug-in repellers have been mostly negative, so use it as one layer alongside sealing gaps, food storage and traps.

How many Repellio units do I need?
