This could be worth doing. You can make your own mosquito trap with nothing more significant than a two-liter bottle, some brown sugar, and a gram of yeast. Even if it doesn't work so well, it's cheap and looks like a good excuse to drink a bottle of Mountain Dew.
Here's the gist of it: Cut the top off the bottle, put in some water and mix a solution of brown sugar, and add a pinch of yeast. Invert the bottle top you cut off and stick it in the bottle to create a funnel.
Presumably, the mosquitos will fly into the bottle because they're attracted to the carbon dioxide given off by the fermentation going on in there. The nasty little buggers will get trapped in the bottle and probably suffocate. Neat.
