In the summer, I am annoyed by small numbers of mosquitoes. Since they are not many, I just use an electric racket to take care of them.
The main issue I have with the racket is visibility: when a mosquito is in the room, it is hard to find. It happens often that I see it, but before I grab the racket, it disappears from my field of view, even if I try to follow it with my eyes. I have noticed that mosquitoes are much harder to track on dark backgrounds.
What can I do to my room to better see the mosquitoes? Repainting the walls and furniture in white is not an option.
