How to Replace a Bug Zapper Bulb

Bug zappers provide an efficient way to trap and kill flying insects outdoors. These electronic devices lure bugs in with ultraviolet light then eliminate them with an electrified metal grid. But over time the bulb producing the attractive light will burn out and need replacing. Here is a step-by-step guide to changing out a burnt-out bug zapper bulb for a new one.

Supplies Needed

• Replacement bug zapper bulb (check wattage/type of your model)
• Work gloves
• Safety glasses
• Phillips or flathead screwdriver
• Step stool (for high mounted models)

Steps to Replace Bug Zapper Bulb

1. Unplug the zapper. Disconnect the electrical cord so the device is not live when you access the light housing.

2. Locate the bulb compartment Bug zappers have a small compartment that holds the bulb and protects it from the elements, This is usually found at the bottom or back of the unit,

3. Open the housing. There will be a movable panel, lid, or other access point secured with screws or a locking mechanism Use gloves when handling in case of electrified parts

4. Remove the old bulb. Gently grasp the bulb and pull it straight out from the socket. Do not twist. Dispose of the burnt-out bulb properly.

5. Inspect the socket. Look for any signs of damage, corrosion, dead insects, or debris. Clean if needed so the socket contacts are clear.

6. Check the replacement bulb. Confirm it matches the wattage and style of the original bulb. Never exceed the rated wattage.

7. Install the new bulb. Align the bulb pins with the socket holes and press gently but firmly until seated fully. Do not force.

8. Close the housing. Return the protective cover and secure it back in place with screws or by closing the clasp.

9. Plug in the zapper. Reconnect the power cord and turn on the device to ensure the new bulb illuminates properly.

10. Test the attractiveness. Turn the zapper on after sunset and observe if insects are drawn to its ultraviolet glow. Catch some bugs to verify it is working.
