This one works, and skip the bait. You really don't need to attract every mosquito in the state.  Remember, you want to draw the mosquitoes AWAY from your area, not to it, and that's exactly what the blue light does.  Great product tried and true. There are others out there readily available in your big box store.  This one will do the job better. I don't know why stores have stopped carrying them locally. Perhaps because they can buy for less and have a greater profit?  I have returned 3 of the other brands to the store and ended up coming to Amazon where I really this tried and true Flowtron which I should have purchased first.
