Features
- Working principle Repeller:Ultrasonic insect indoor repellents use ultrasound to stimulate the brain neurons of pests. Long term stimulation can cause damage to the neurons of pests, thereby achieving the goal of expelling pests
- Functional upgrades in 2024. Intelligent frequency conversion with three different sound wave frequencies, covering a frequency range of 20KHZ-60KHZ, can more effectively deal with various types of pests and keep your family away from pest infestation
- Green Way To Repel Pests: Throw away harmful poisons, hazardous chemicals and traps commonly, which always used in households and control technicians. Ultrasound is inaudible to humans and household pets
- Energy saving and money saving. Its power is only 3-5 W, even lower than the power of ordinary small desk lamps, without the need for batteries, plug in and use, truly achieving low energy consumption and high efficiency
- Work progress process:The typical results can take 1-2 weeks depending on the severity of the pest infestation. Mostly can see the electronic pest repellent results within 3-4 weeks

Overview This Ultrasonic Pest Repeller claims to deter a wide range of pests—including roaches, rodents, spiders, ants, and mosquitoes—using high-frequency sound waves. The 6-pack set ensures coverage for multiple rooms, and the 3-mode switching (continuous, intermittent, and hybrid) allows customization based on infestation severity. But does it really work? Here’s a detailed breakdown. Pros: ✅ Non-Toxic & Chemical-Free – Unlike sprays or traps, this repeller is safe for kids and pets (except rodents like hamsters or guinea pigs). No mess, no poison. ✅ Wide Pest Coverage – Targets common household pests, including mice, roaches, ants, spiders, and mosquitoes. ✅ 3 Adjustable Modes – Continuous: Steady ultrasonic waves for heavy infestations. Intermittent: Alternating frequencies to prevent pest adaptation. Hybrid Mode: Combines ultrasonic + electromagnetic pulses for enhanced effectiveness. ✅ Energy-Efficient & Low Maintenance – Plugs directly into outlets, consumes minimal power, and works 24/7. ✅ 6-Pack Value – Covers multiple rooms (recommended: 1 per 800–1,200 sq ft). Cons: ⚠️ Variable Effectiveness – Some users report strong results (especially for mice & spiders), while others see little to no change (particularly with roaches and ants). Ultrasonic waves don’t penetrate walls well. ⚠️ Pests May Adapt – Some insects (like roaches) can become habituated to ultrasonic frequencies over time. ⚠️ Not Instant – Takes 2–4 weeks to see noticeable results as pests gradually leave the area. ⚠️ Pet Considerations – While safe for cats & dogs, rodents like hamsters or rabbits may be stressed by the high-frequency sounds. Real-World Performance Best for: Mice, spiders, mosquitoes (most consistent results). Moderate for: Ants, roaches (works better in combination with other methods). Least Effective for: Severe infestations (may need traps/baits as backup). Tip: Place repellers in open areas (not behind furniture) and pair with good sanitation (sealing food, fixing leaks) for best results. Final Verdict: 4/5 ★★★★☆ This ultrasonic repeller is a solid, eco-friendly option for preventative pest control, especially for rodents and spiders. However, managing expectations is key—it works best as part of an integrated pest control strategy, not a standalone miracle solution. Who Should Buy It? ✔ Those looking for a non-toxic, hands-off pest deterrent. ✔ People with mild to moderate pest issues (not severe infestations). ✔ Households wanting long-term prevention rather than instant kills. Who Should Skip It? ✖ Those with major roach/rodent infestations (may need stronger measures). ✖ People expecting immediate results (requires patience). Bottom Line: A worthwhile investment for maintenance pest control, especially given the 6-pack value. Use alongside sealing entry points and cleanliness for optimal results.

I've been using these plug-in ultrasonic pest repellent devices for several months now as part of my comprehensive pest management approach. While I can't definitively measure their individual impact since I use multiple pest control methods simultaneously, I genuinely feel they're filling important gaps in my overall strategy. What I really appreciate about these units is the thoughtful design that includes three different sound frequencies targeting various pest species. This versatility means I'm not just addressing one type of unwanted visitor - whether it's rodents, insects, or other common household pests, there's a specific frequency designed for each. It shows the manufacturer put real consideration into creating a more comprehensive solution. While I can't isolate their exact contribution to my pest-free home (since I also use other preventive measures), I believe they're providing valuable supplemental coverage. Sometimes the best pest control approach is layered defense, and these units seem to be doing their part in keeping my home comfortable and pest-free. One of the biggest advantages is their affordability, which allowed me to purchase enough units to place them throughout my entire home - essentially anywhere I had an available outlet. I was able to achieve comprehensive coverage without breaking the bank. For areas like my attic where standard outlets weren't available, I used light socket to plug adapters, which allowed me to install two units even in that hard-to-reach space. This flexibility in placement options means I can target pest entry points and hiding spots that might otherwise be missed.

I bought this after a bat found its way into my house. I keep them in the blue setting most of the time, yellow when it’s a rodent-y time of year. I’m young enough to hear the noise on red and not on yellow unless I’m right next to it. Didn’t seem to bother my cat.

Haven't seen mice in my house since I got these. I did see one in my garage still though so I put another out there and haven't seen any sign of them. I was so paranoid that I had 4 of these in my house (±1400sq ft) at all different levels, depending on whether I will be in that room. They give me a headache though so I've kept them at level 1 most of the time now since I haven't seen any pests, and also because I worry about it bothering my dogs. It doesn't seem to be a problem but I want to be considerate. I haven't seen as many other bugs or spiders so that's a plus. I was really afraid to try these since there is mixed reviews but I was desperate to get rid of the mice so I'm glad they work and I don't have to empty mouse traps. Still paranoid though so I'm using both and haven't caught anything or seen signs.

Have not had an ant issue in the house since installing these pest repellers in every room. Prior to installation we were playing "Whack- a- mole" or "Whack- an-ant" all summer long from room to room.

Living in the South brings in lots of bugs. I was using roach bait pellets but these roaches are too darn smart. They won’t touch them. They grow the cockroach’s big down here. Big enough that you can hear them walking. It’s been 3 weeks since I’ve been using these plug-ins. I wasn’t sure if this would work but they have me singing Hallelujah! I have not seen a cockroach since I plugged them in. I placed the units in the kitchen and dining room for starters. Picking up a few more now that I know they work.

Not sure they worked. I bought these after trying a different product to get rid of roaches. Neither product eliminated the pests. I bought Raid traps and all the roaches have been gone for months. Maybe it was a combination of the products that did the trick? I will say I think these for rid of the silverfish in my bathroom though!
