Here is an article on SWD in Minnesota. The flies can start laying eggs the day after they emerge, so you'll need to take a look at the article for guidlelines: http://www.extension.umn.edu/garden/insects/find/spotted-wing-drosophila-in-home-gardens/

One way to decrease the population in your yard is to remove all infected fruit, including what has fallen to the ground.
