## Common ground
All options refer to devices designed to kill flies, mosquitoes, or other pests.
## Options at a glance
**3926.90 – Plastic swatters**
- **Defining trait:** Uses non-electrical, physical impact (e.g., a solid plastic paddle) to kill pests.
- **Typical examples:** Traditional handheld fly swatters, plastic pest killers with no power source.
- **Best fit when:** The device has no electrical components and relies solely on manual striking.
**8543.70 – Electrical swatters/zappers**
- **Defining trait:** Uses electric current to kill pests, typically via a charged grid or mesh.
- **Typical examples:** Battery-powered electric fly zappers, plug-in mosquito killers with electrified grids.
- **Best fit when:** The device emits a shock or uses electricity to kill pests.
## Key differences
| Feature | 3926.90 (Plastic) | 8543.70 (Electrical) |
|-----------------------|--------------------------|-------------------------------|
| Power source | None (manual) | Battery or plug-in electricity |
| Killing method | Physical impact | Electric shock |
| Moving parts/energy | None | Electrified grid/mesh |
## How to choose
- Does it require batteries or a power plug? → 8543.70
- Is it used by hand and relies only on hitting the pest? → 3926.90
## Overlaps & pitfalls
A device may combine both features (e.g., a plastic swatter with an electric grid). In such cases, the **main function** determines the code: if killing is done primarily by shock, use 8543.70; if by impact, use 3926.90. If unclear, prioritize based on the device’s primary mechanism
