PestPulse vs Repellio: which one fits you?
Both are small, chemical-free devices that plug into a wall outlet and run around the clock, and both brands describe the same trio of ultrasonic, electromagnetic and "bionic" waves. They differ in how much space each brand says one unit covers, how the packs are sized and what each store asks for if you send one back.

Our verdict
PestPulse is a white plug-in unit with a front button and a green light that shows it's running. The brand says its pulses mimic predator sounds and that the device shifts its frequency pattern over time so pests don't get used to it. It rates one unit for up to 900 sq ft, without saying whether that means one open space or several rooms. It's sold singly and in packs of 2, 3, 4, 5 and 10, from $19.50 a device on the ten-pack, by a New York company that prints its address and phone number on the checkout.
Repellio is a compact, egg-shaped unit with a blue light strip, and its brand makes the more modest claim: up to 120 sq ft per device, about one room, with several units suggested for larger spaces. It also publishes more of what a buyer wants to know, including the pests it's aimed at (mice, rats, cockroaches, ants, mosquitoes, spiders, flies and termites) and a timeline: its FAQ says most pests begin leaving within 48 hours, while a chart on the same page describes 3 to 4 weeks. It comes singly and in packs of 3, 5 and 10, from $20.00 a device on the ten-pack.
On price per device the two are close. Repellio costs less if you're buying a single unit, the five-packs are within a few cents of each other, and PestPulse is slightly cheaper on the ten-pack. Shipping is added at both checkouts, and Repellio's fee was the lower of the two at every pack size when we checked. PestPulse's checkout opens with the four-pack selected, and Repellio's opens with the three-pack and may show an optional extended warranty, so check the quantity and the total before you pay.
The research on plug-in sound repellers is mixed, and for store-bought units it leans negative. A University of Arizona Cooperative Extension review concluded that commercial sonic devices haven't been shown to work in homes, and UC IPM notes that mice get used to repeated sounds and that ultrasound doesn't reach behind furniture or through walls. On the other side, a 2023 laboratory study found German cockroaches avoided certain ultrasonic frequencies. Neither brand publishes its frequencies, its output or a test of its own device. So treat either one as an extra layer next to the steps with strong evidence: seal gaps, remove food and water, and set traps if mice are already inside. Plan on one unit per problem room, and keep both out of rooms with pet rodents such as hamsters or guinea pigs.
Returns: PestPulse, 30 days, original condition; Repellio, 30-day returns (unused). PestPulse refunds the price paid minus shipping and handling, and Repellio's change-of-mind returns need the device unused in its packaging, so with either brand plug in one unit first and keep the rest sealed. Neither store has an independent buyer rating we could show yet.
If you want to cover several rooms and like having a two-pack or four-pack to choose from, start with PestPulse. If you have one small problem room, such as an apartment kitchen, a dorm or a garage corner, and prefer the brand with the room-sized claim and a published timeline, Repellio is the one to look at.
