- Access the Bulb: Locate the access point for the bulb, typically at the bottom of the bug zapper. This may involve rotating a tray or unscrewing a cover.

Operating Instructions
Once the replacement bulb is installed, the bug zapper will operate as designed. Ensure the zapper is placed in an optimal location for attracting and eliminating flying insects, typically in a dark area away from competing light sources.
- For outdoor use only.
- Keep out of reach of children and pets.
- Do not touch the internal grid while the unit is powered on.
Maintenance
To ensure the longevity and effectiveness of your bug zapper and its new bulb:
- Regular Cleaning: Periodically clean the insect collection tray and the internal grid of the bug zapper. Always unplug the unit before cleaning.
- Bulb Lifespan: UV bulbs typically have a lifespan of approximately 3,000 hours of use. Replace the bulb annually or when you notice a decrease in its effectiveness, even if it still lights up.
- Storage: If storing the bug zapper for an extended period, remove the bulb and store it in a cool, dry place to preserve its lifespan.
Troubleshooting
If your bug zapper is not functioning after replacing the bulb, consider the following:
- Bulb Not Lighting Up:
- Ensure the bulb is fully seated in its socket. Gently push it in firmly.
- Check if the bug zapper is properly plugged into a working power outlet.
- Verify that the power switch on the bug zapper is in the "ON" position.
- If you have a spare bulb, try installing it to rule out a defective new bulb.
- Reduced Effectiveness:
- The bulb may be nearing the end of its effective lifespan, even if it still glows. UV light output diminishes over time.
- Ensure the bug zapper's grid is clean and free of insect debris.
- Relocate the zapper to a darker area where it can be the primary light source for insects.
