TROUBLESHOOTING

Unit will not light, no apparent grid voltage

•  Make sure the unit is plugged into a working outlet
Unit will not light, grid has voltage

• Check bulb to make sure it is seated properly
• Replace bulb if necessary 
Unit appears to be working properly but insect population does not seem reduced
•  Check surrounding area for sitting water, insects breed in these areas and 

should be eliminated at the source.

•  Allow more time. It will take some time for insects to find the unit and also  

for there to be an impact on their reproductive cycle.

•  Try moving the unit to another area of the yard. If you are in between the  

unit and the source of the insects, they will have to fly by you to get to the  

unit and you may actually notice an increase in insects.

Unit is constantly arcing (sparking)
•  Clean the unit per the instructions in this manual
•  The unit will arc upon plug in and then stabilize. This is normal.

(BK310 AND BK510 MODELS ONLY) 

Unit makes a slight humming sound when plugged in.

•  This is due to relative humidity levels and is normal. This will not  

impact performance.

The unit does not come on during the daytime.

• Check the sundown sensor which may be activated and only allows unit  

to operate dusk to dawn. See figures 2 and 3.

other questions, please call consumer relations at 800-477-0457 or email

CHANGING BULBS

Only use Stinger replacement bulbs. Bulbs should 
be replaced annually to maintain optimal UV 
effectiveness. Even though the bulb’s light may be 
visible to you, its ability to attract insects diminishes 
over time. If the bulb fails to light or the color of 
the light changes to yellow or orange it is time to 
replace the bulb. See PRODUCT SPECIFICATIONS 
for bulb replacement type for your device.

To order replacement bulbs and lures go to www.StingerProducts.com or  

call 1-800-477-0457. In Canada, you can also visit Canadian Retail stores  

to purchase these items.

CLEANING

As the unit kills insects, most of the insect remains will be vaporized or fall down through the 
unit. Some debris may be left on the zapping grid or may accumulate in the base of the unit.  
This may reduce the effectiveness of the device. Check your device frequently and clean the  
unit regularly. The time in between each cleaning will vary depending on your insect population. 
1.  Unplug and remove entire unit from hanging position.
2.  Remove bulb from unit to avoid damage (see section CHANGING BULBS).
3.  Using a small brush or stick, gently remove any insect remains from the bottom of 

the bulb door and enclosure.

4.  If available, compressed air may be used to clean the unit.
5.  Never use water to clean the unit. Water may damage the electrical components.
6.  Be very careful not to move or adjust the metal killing grid in any way.
7.  Once the unit is clean replace the bulb, return unit to hanging position and reconnect  

to power source.

 OCTENOL MOSQUITO LURE

A NOsquito

® 

octenol lure by Stinger (NS16 model series) is included with the unit. 

Research has shown that octenol is effective in attracting many species of mosquitoes 

and biting flies. This lure has slow release properties and increases the effectiveness  

of attracting insects to the unit. For Canada, use replacement lure NS16-6-CAN and 

replace every 14 days. 
1.  Open the lure by peeling off the foil lid.

2.  All BK series models have a specially designed  

holder built into the base. Simply slide the lure  

into this holder with the exposed octenol side  

facing in to the device 

(Figure 4)

. The lure should  

fit snugly and the tension tabs should hold it  

securely in place.

3.  To remove – place thumb into recess and slide  

lure out. Discard appropriately in trash receptacle.

1.  Unplug and remove entire unit from hanging position.
2.  Turn the unit upside down. DO NOT REST THE UNIT ON SURFACE WITHOUT 

CONTINUING TO SUPPORT IT. It will not stand on its own and was intentionally 

designed for use in a hanging position.

3.  Use thumb to depress easy tab and open bulb door.
4.  Remove old bulb by pulling straight out and dispose safely in accordance to  

local laws. (Figure 5).

5.  Insert new bulb making sure it is properly seated in the socket.
6.  Close the bulb door by snapping it back into place.
7.  Place the unit back into the hanging position and plug into extension cord.

NOTE: If unit fails to light after replacing bulb, unplug unit, take it down, remove the 

bulb and reseat it in the socket.

6.  BK310 and BK510 models have 2 settings – 24 Hour Mode and

 

Dusk to Dawn Mode.

 a. 

To select 24 Hour Mode, slide the grey button on the cap down so that it covers the sundown 

sensor. The unit will remain ON 24 hours a day 

(Figure 2).

 b. 

To select Dusk to Dawn Mode, slide the grey button up, revealing the sundown sensor. The unit will 

automatically turn ON at dusk, operate through the night, and turn OFF in the morning

 

(Figure 3)

.

7.  Using the available lure will add to the effectiveness of the unit by adding scent proven to attract more 

insects to the unit.

8.  It is recommended that this unit be put to use in early spring and left out until late fall to  

maximize effects.

9.  The unit is designed to withstand moderate rain but should be taken down and stored indoors  

during severe weather.
