Great little article in Farm Show, Vol 35, No 5 (2011) on milk jug fly traps. Paul Olson of Minnesota hasn't sprayed is fruit trees for 41 years, and has not bitten into any fruit with worms. Whenever he plants a new tree, he places a 1 gal milk jug with 1/3 water, 1/3 vinegar, and 1/3 sugar (2 cups each-ish) next to it, and as the tree gets big enough, he ties it to the crotch of the tree. The bugs go in and can't get out, and at the end of a season he'll have an inch of bugs in each one. (horse flies, deer flies, mosquitoes, etc). Once a year he changes the jugs. He raises honey bees, and they never go into the jugs. He grows apples, pears, plums, kiwis, apricots, cherries--all as chemical free as he can. And he says his guinea hens and chick help a bunch too, of course.

Any special preparation on the milk jugs? Cut holes or anything like that to make them effective traps?

I think just leave the cap off. The bugs smell what's inside, come in no problem, and then can't get out.

great idea if it really doesn't attract pollinators..i'd hate to lose my pollinators to it.

I have used sticky traps successfully, just take a trap the color of the fruit and coat it with sticky stuff..catches the flies..best to put them out before the fruit sets..
