Are ultrasonic pest repellers just a scam?

Hey everyone,

I’ll admit I was skeptical when my neighbor swore by ​ultrasonic pest repellers​​ – but after battling mice in my garage for months, I decided to test them myself. I bought the “SonicShield Pro” units ($35 each) and placed them near entry points. ​​Within 2 weeks​, the scratching noises stopped! No droppings for 3 months now. I know studies are mixed, but in my case, they clearly worked.

​Let’s share real-world evidence:​​

  1. ​​Success stories​​ – What pests did repellers eliminate for you? (Mice? Spiders? Roaches?)
  2. ​​Critical factors​​ – Placement, brand, room size – what made YOUR repeller effective?
  3. ​​Scientific support​​ – Newer models claim improved frequency tech – is there truth to this?
  4. ​​Hybrid solutions​​ – Did combining repellers with natural methods (e.g., peppermint oil) boost results?

I believe these devices deserve a fair trial! Share your honest results below

100% effective on spiders! My basement had webs everywhere. Installed ​​4 ultrasonic units​ and added dehumidifiers. ​​Spiders gone in 3 weeks​.

2021 Danish study showed ​​65-70% rodent reduction​​ with ​​dual-frequency repellers​​ (25kHz + 50kHz). Cheap single-frequency models fail – you get what you pay for!

@NightFlyer3 Link to study? Need ammo to convince my doubting spouse.

[Journal of Pest Science, Vol 94(2)] – Higher kHz = harder for pests to adapt!

Worked for ants AND my cat stopped freaking out!

As a lab tech: Newer repellers ​​pulse frequencies​ (e.g., 0.5-sec intervals) to prevent adaptation.

@RodentResearcher This explains older study failures, tech evolved!

Saved my garden shed! Used cheap repellers – failed.

Combined with ​peppermint oil cotton balls​​ – repellers alone reduced mice by 50%, but adding natural deterrents made it 95%! Synergy works.

Ate my words Repellers + ​​steel wool in holes​​ eradicated garage rats. My takeaways:

  • Use ​​≥2 units per room​
  • ​​Replace annually​​ (frequency weakens)
  • ​Works best in enclosed spaces​
