Where to buy CO2
Which CO2 bottle do I need?
For our CO2 traps, we recommend using a 10 kg gas bottle. However, you could also use 5, 6, or 20 kg if you prefer.
Where can I get the CO2 bottles?
The gas bottles are not included in the contents.
The gas bottles can be acquired or rented at drink retailers or bottle depots for a deposit. A door-to-door delivery service may also be available in some locations.
Depending on the country, we partly have cooperations with CO2 companies. Please switch to the respective language for more information.
How long does a gas bottle last?
How often you need to change the gas bottle depends on:
- what size you use and
- which release rate of CO2 you use
If CO2 is released continually over 24 hours with our recommended release rate of 0.5 kg/day, a 10kg CO2 tank will last about 20 days.
The BG-CO2 Timer - save CO2
Depending on the mosquitoes you are bothered by, the mosquito species are active at different times of the day and night. Thus, with our BG-CO2 Timer you have the possibility to limit the CO2 output to the main activity times of your local mosquitoes (for example only ten hours a day). In this way, the CO2 bottle lasts longer and you save money.
We recommend following time frames for the different mosquito types:
- House mosquitoes: 6am - 9am and 4pm - 11pm
- Flood water mosquitoes: 7am - 11pm
(At the beginning of the nuisance, we recommend to start with 24 hours continuous CO2. When the population decreases, the BG-CO2 Timer can be switched to the recommended time frames.) - Tiger mosquitoes: 7am - 10pm
Recommendation for the handling of gas bottles:
No additional emission of CO2
The CO2 in gas bottles is not explicitly produced to be bottled but is a recovered by-product from other industrial processes.
Therefore, the use of CO2 from gas bottles as a mosquito attractant does not represent an additional CO2 contribution to the planet, but is merely a delayed diffusion of CO2 as industrial waste.
