We have in our land a plum tree with us great sweet (really egg - large) fruits. The only downside: the maggots of the plum moth find the class and we look into the tube! Conclusion: a plum tree for preserving plum maggots we do not need, therefore, saw down or fight with chemistry. We decided against the spraying and for 2 maggot traps. The success is great, after we hung up the first case in a neighboring cherry tree in the spring and have wrapped Leimringen the branches of the plum tree, we could see the still green plums are no needle marks. The first case is to be replaced after 6 weeks by the 2nd case (in 14 days). The currently suspended maggots trap is full of small black butterflies (plum fruit) and if this continues with the 2nd case so we can adjust this time to a good plum harvest. Had to buy these traps earlier instead annoy. Although it will take some time to harvest and plum fruit with security also comes into its own, so we do not go back empty-handed this time determined. Next year we will do it again !! Therefore: This Made traps are worth your money!
