If you would like to know more about how to use or maintain your Gecko, or any other questions, check out our frequently asked questions below.
Female mosquitoes require protein found in blood to produce eggs and most are not fussy about the source of the blood. The receptors in mosquito antennae are very sensitive and mosquitoes use these to identify their prey. Prey is identified from any carbon dioxide, body odour, lactic acid, blood type as well as secretions.
Carbon Dioxide is what we exhale. Our body odour is the result of bacteria on our skin that mixes with sweat. Lactic acid passes through our skin after eating certain foods or when we’ve been active. Mosquitoes are mostly attracted to blood type O and least attracted to blood type A. We “advertise” our blood type by secreting compounds through our skin.
Other attractants include body heat and dark clothing.
Gecko Zappers are primarily designed to attract mosquitoes. Moths and other insects commonly attracted to light will also be drawn towards the zapper.
While flies are attracted to UV light, they are generally more active during the daytime. If operated indoors and away from windows and competing light sources, units will attract and kill flies. Used outdoors during the daytime, a zapper is less than ideal where flies are a problem.
- Citronella or Horsemint will repel mosquitoes.
- Marigolds – contain pyrethrum, a compound that’s used in many insect repellents
- Catnip – reported to be 10x more effective than DEET. You can also use this in cooking.
- Ageratum – emits a smell that is offensive to mosquitoes.
How & Where
Yes, depending on which model, the majority of Gecko models are weatherproof. Ensure any power connections are weatherproof.
Mosquitoes are most active from dusk and become less active again after sunrise. For best effect, switch on the unit an hour or two before sunset. Leaving the unit on overnight may help reduce any surrounding mosquito populations.
The Gecko range includes models suited to virtually all situations. To make product selection easy, we’ve devised a simple product selector.
A zapper is best placed away from human activity and also competing light sources. Preferably out of windy locations also. Ideally, hang at a height of around 2.5 metres. Check out our How to Guide for more information.
Gecko zappers and trappers are designed to require minimal maintenance. Before commencing any maintenance, ensure units are disconnected from any power.
Zapper catcher trays or the trapper basket should be emptied from time to time. It’s important to ensure a Zapper’s high voltage grid is cleared of any larger “stuck” bugs, as these will affect the unit’s performance. Check out our How to Guide for more information.
The zapper lures insects with its ultra-violet light. Insects are electrocuted on contact with a high voltage grid surrounding the lamp. Dead insects will then drop into the in-built catcher tray.
Edison screw and tubular Gecko lamps should generally last around 5,000 hours. For optimum life, we recommend switching on your unit for at least 4 hours at a time. Shorter durations or frequent switching on and off will shorten the lamp life. Other factors include excessive heat or cold. LED lamps have a general life of up to 50,000 hours.
Yes, Edison screw and tubular Gecko lamps are readily available at Bunnings. The silver coloured rating label on your zapper shows the model number of the replacement lamp. LED lamps are not replaceable.
The majority of Gecko Zappers enable tool free lamp replacement. Detailed instructions are included in the instruction manual supplied in the pack. LED lamps are not replaceable.
Units with conventional lamps start at 7W and go up to 50W, depending on the model. The 50W model costs less than a couple of cents per hour to run. Models using LED lamps are significantly cheaper to run.
When bugs hit the high voltage grid, a cracking noise will be heard. The noise level will generally depend on the size of the bug and also grid voltage of the zapper. If the cracking noise is an issue, consider the near silent Gecko Triple Lure Insect Trapper model IT560.
Combined with UV light and organic matter left behind from bugs, the TiO2 acts as a catalyst to produce carbon dioxide (CO2) that helps attract mosquitoes to the insect trapper. The TiO2 will last indefinitely as it is a catalyst and is not consumed in the process.
Model LT4S uses a Lithium Battery. Depending on environmental factors (especially temperature) the battery should continue to accept a charge up to 2000 times. The battery is easily replaceable – see the product manual for details and specifications.
This switch has options for Zapping, Light, Auto or Off.
The Gecko Xtreme Commercial model is supplied with a Philips brand S2 starter. Other 4W-65W brand starters including Osram or Crompton can also be used.
The unit is powered up as soon as it’s plugged in. The UV light will light up when the unit is plugged in.
Check the unit is plugged in and power is switched on. Ensure the unit’s power switch is also on. The power switch is located below the top cover and covered by a clear rubber dome. If the fan doesn’t appear to be turning, switch off unit, remove catcher basket and ensure there are no large bugs caught near the fan blade.
The area around the fan should be cleaned regularly with the supplied brush. In the event the unit still won’t operate, call us on 1300 360 211.
I have a cordless rechargeable model with 3-way switch, but the UV light doesn’t seem to be working.
When switched to zapping, a built in auto on off sensor will ensure the zapper only functions when it’s dark. You can test the zapper function. Switch to Zapping and place the unit upside down on a flat surface. The unit’s blue UV light will come on.
The unit is supplied with a USB cable only. These days, charging plugs are very common place and arguably found in almost every home. In the interest of keeping the product’s price down, we opted to include a cable only.
A grid that’s clogged with dead bugs or debris may result in a reduced ability to generate a high voltage. Switch off, unplug the unit and clean the metal grid and horizontal bands thoroughly with the supplied brush.
Gecko products carry a 12 month warranty from date of purchase. Gecko Xtreme models carry a five year warranty.
