Every spring, the same products pop up on Amazon: ultrasonic pest repellers priced at $25, $30, even $40 for a 4-pack. They promise to chase away mosquitoes, mice, and cockroaches with sound. But what does one actually cost to make? I asked around.
What Is an Ultrasonic Pest Repeller?
An ultrasonic pest repeller is a small plug-in device that emits high-frequency sound waves to repel insects and rodents. The upgraded versions come with electromagnetic technology, night light, and multiple frequency settings. They’re marketed as a chemical-free way to keep pests away.
What’s Inside That $25 Repeller?
- Speaker: Piezoelectric speaker, 20-65 kHz frequency
- Power: 5W, plug-in design
- Features: Night light, variable frequency, electromagnetic mode
- Body: ABS plastic, white
- Coverage: 800-1200 sq ft per unit
Amazon Price: What Are People Actually Paying?
| Brand Tier | Amazon Price | Example |
|---|---|---|
| Premium (Branded) | $39.99 – $59.99 (4-pack) | Riddex, Neatmaster |
| Mid-tier | $19.99 – $29.99 (4-pack) | Non-brand with good reviews |
| Value / New launch | $12.99 – $17.99 (4-pack) | No-name brands with launch discounts |
What the Chinese Factory Actually Charges
| Price Point | Cost (USD per unit) | MOQ | What’s Included |
|---|---|---|---|
| Factory Price (Bulk Order) | $1.50 – $3.00 | 1000–5000 pcs | Basic repeller, no retail box |
| Factory Price (Custom Logo) | $3.00 – $6.00 | 500–1000 pcs | Night light, retail box, custom color |
Why Don’t Most Sellers Buy Directly From Factories?
Because ultrasonic output and reliability vary wildly. Some cheap repellers produce no sound at all, or burn out after a week. A good sourcing agent tests every sample — checks frequency output, sound level, and durability — before bulk production.
The Profit Margin Math
You buy 1000 units at $3.50 each, sell on Amazon for $19.99 (4-pack, so $5 per unit).
| Cost Item | Per Unit | 1000 Units Total |
|---|---|---|
| Factory Price (with retail box) | $3.50 | $3,500 |
| Shipping to Amazon (sea + fulfillment) | $0.50 | $500 |
| Amazon FBA Fee | $2.00 | $2,000 |
| PPC Ads (average 10% of revenue) | $2.00 | $2,000 |
| Total Cost | $8.00 | $8,000 |
| Revenue (selling price × 1000) | $19.99 | $19,990 |
| Net Profit | $11.99 | $11,990 |
| Net Margin | ~60% (after all fees and ads) | |
Sourcing Tips for Ultrasonic Pest Repellers
- Frequency test. Use an ultrasonic detector. If it’s not in the 20-65kHz range, it won’t work.
- Sound level test. Turn it on. If it’s too loud, customers will complain.
- Durability test. Run it for 100 hours. If it burns out, it’s cheap.
- Night light test. Turn off the lights. If the night light doesn’t work, it’s defective.
- FCC/CE certification. Amazon requires certification for electronic devices.
Is This Product Worth Selling in 2026?
Yes, but it’s seasonal and competitive. To stand out, you need: multiple frequency settings, night light, electromagnetic mode, and good reviews.
