T. D., edge of a village in Mecklenburg-Western Pomerania, Germany
* “We are very happy about the mosquito trap and also very satisfied and impressed how effective it is. We live at the edge of a village, and we have only one trap. It is placed at a corner of our property partly under a pine to be in shade. I constructed a framework for it to be at a certain height above the ground (~ 40 cm). Additionally I constructed a simple roof out of a bunch of planks. In the summer / fall, we had to empty the trap more often, and there were only mosquitoes caught. In the fall, there were several wasps, maybe 5–10. A little later, there was a quite short period were the trap caught masses of small flies (approximately 2–4 mm).
The CO2 bottle from “Unterbichler” was easy to install and also easy to operate. We chose the smaller output of CO2.
The only thing I tried to improve was the fan. It is not very quiet. I tried to find a quiet computer fan, e.g., one from Noctua, NF-S12A, however, I realized that the amount of air is different from the amount of air in the trap. I cannot remember if it was more or less. In order to avoid that the new fan would be too weak or too strong (it also catches bigger insects), I used the original fan. The noise is unpleasant on quiet summer evenings when the trap is only 10 m away. The Noctua fans are very quiet, but unfortunately not suitable for the outside. Since I have a small roof, I still would have tried. If you changed to Noctua or something similar, I would be glad, because you could adjust the correct amount of air. (Most of the fans can be controlled with both voltage and PWM). I don’t mind paying a higher price.
I also was thinking about operating the trap with a lead accumulator (from a car) to avoid power cables coming from the house. Unfortunately, I did not have time to follow up with this. Maybe this is a project for the following summer.”
