Installing and commissioning the mosquito trap

You have just purchased a Qista mosquito trap. Here is some practical advice on how to install it and start making the most of your mosquito-free outdoors.

Installation by Qista

If you have chosen installation of your trap by Qista’s teams in the options proposed (only available in the South of France zone), you will benefit from a comprehensive installation and start-up service. Our technicians will look after everything! 

After installation, Qista offers several maintenance services to keep your machine in good condition. To find out more about Qista’s services, visit the delivery and collection options page.

Installing yourself

If you are going to install the mosquito trap yourself, nothing could be simpler! Simply follow these steps:

  1. Find the location recommended on the location study and place your trap there.
  2. Start assembling the trap as shown on the supplied installation instructions.
  3. Connect your trap to the electricity supply.
  4. Install the consumables: connect the CO2 as shown in the instructions and place the lure in the trap chimney.

Is this your first installation? Follow the guide!

That’s it, everything is up and running! All you need to do is programme the operating times:

  • If you have a BAM Evo 2+, the operation is carried out directly on the programmer located inside the machine.
  • If you have a Smart BAM, the different programming modes can be controlled from the Qista app.

Maintaining and servicing your Qista trap

Already using the Qista mosquito trap? Here is some advice to keep it effective and maintain your machine.


To keep the mosquito trap effective, the consumables (lure and recycled CO2) need to be replaced every month. If you have a connected Smart Bam trap, you can monitor the status of the consumables via the Smartphone app.

Running out of consumables would allow mosquitoes to rapidly settle in the protected area. A female mosquito can lay up to 200 eggs every 48 hours. Once the larvae have hatched, thousands of mosquitoes would invade your outdoor spaces.

As for the CO2 filter, this should be replaced every year, preferably at the start of the season.

Changing the gas filter: an important step

The gas filter ensures that your mosquito trap works properly. It means that any impurities released can be filtered out so as to avoid clogging up or blocking the solenoid valve. It is therefore essential to replace it once a year, preferably at the start of the season

Replacing the consumables

The consumables should be replaced every month. The olfactory lure starts losing its effectiveness after 30 days and is no longer potent enough to attract female mosquitoes from a distance. Its effectiveness decreases gradually making it useless.

The CO2 operates in the same way as a conventional gas canister, it empties as it is used. A CO2 canister used with a Qista machine provides 1 month of diffusion for a 15-hour per day programme (average Qista recommendation for significant trap effectiveness in a moderately infested area). For highly infested areas, daily programming must be increased and the CO2 will be used up faster.  So you might need to replace it more often, depending on your usage. For other areas, daily usage of 15 hours per day will make it possible to use the canister for over one month, as recommended by Qista.

The QISTA mobile app enables you to view the number of days remaining before the end of your CO2 refill and your lure. Just click on the clock icon to update the refill level when your consumables have been changed.

Storing consumables

When you purchase packs of consumables for the whole season, you might need to store them somewhere before using them. You can keep the mosquito lures for up to 1 year at a constant ambient temperature, as long as the box is closed. Please ensure that the CO2 bottle is always closed, even when it is empty. Store the CO2 bottle in an open, well-ventilated space. 

See the consumables


Your traps are located outdoors and as a result become soiled by natural phenomena (dust, sap, resin, bird droppings, rain residue, etc.).

They are very easy to clean. First, wash the trap using a sponge and soapy water (you can also use your usual multi-purpose household cleaner).  If the trap is very dirty, repeat the operation. Then rinse using clean water, dry, and your trap will be as good as new!

What to do if there are resin or sap stains? Just rub the stain using a cloth soaked in turpentine or white spirit. Afterwards, remember to clean using soapy water and dry the part in question.


The season is over and the time has come to winter your trap. This is how to do it:

  1. Disconnect the trap from the power supply.
  2. Remove the consumables and shut the lure box (hermetically, using adhesive tape if possible).
  3. Store the trap indoors (garage, garden shed…) or in a sheltered location.
  4. Wrap it in a tarpaulin or sheet to prevent insects or other pests from nesting in it over the winter and damaging the components, or sheltering in the machine piping and blocking it.

To start up your Qista mosquito trap again at the start of the new season, follow the instructions below:

Good pratices

  • Do not cover the trap when it is running
  • Place the trap on the ground, do not place it at height or bury it
  • Do not repaint the trap
  • Only use Qista lures
  • Do not combine the 2 different types of lure - they would cancel one another out
  • Only use CO2 sold by Qista and Air Liquide (in mainland France). Contact us for installation overseas.
  • Do not use gases other than CO2
  • Do not block the openings
