Fresh cherries from our own tree are delicious, but please without maggots. So that these do not make the cherries inedible, there are some ways to combat.
The cherry fruit fly is a pest that spoils many hobby gardeners year after year the cherry harvest. Because when you pick cherries from the tree and bite them heartily, you do not necessarily want to see a white worm or a white grub snaking along the core of the cherry.
The cherry fruit fly lays her eggs in the ripening cherries. These then hatch and the maggots eat their way through the cherry to the core. The interior of the cherries becomes a rather brownish porridge in the places where the maggots have been amicably. In Germany, chemical remedies for the cherry fruit fly are no longer permitted in local gardens - and so the question arises of how to get rid of the annoying flies and protect the cherry tree from infestation by the fruit fly.
Cherry Fruit Fly - That's what she looks like

The cherry fruit fly has similarities to the housefly. But if you look closer, you quickly recognize the differences. With a length of about 5 mm, the cherry fruit fly comes with brownish-streaked wings, green compound eyes and a distinctive trapezoidal yellow dorsal shield. So you can see the cherry fruit fly in the garden.
The problem is that the number of flies is usually so large that simple control measures often show insufficient success. Those who really want to banish the cherry fruit fly from their garden must use a mix of the tips and advice listed below. Because only if you combine the individual methods, you can really have lasting success in combating the cherry fruit fly.
3 methods of controlling the cherry fruit fly
In principle, there are three ways to approach the matter if you want to protect your own garden from the cherry fruit fly. Briefly summarized are the following:
- The precaution already during the planting of cherry trees,
- the direct control of the cherry fruit fly in old tree stands and
- after picking the subsequent attempt to get rid of the maggots.
Avoid cherry fruit fly with proper cherry tree species
The cherry fruit fly is mainly active in late May, early June. She lays her eggs in cherries, which start to ripen at this point in time - so they are no longer green, but gradually change from a yellowish to a reddish color. But there are also varieties of cherry, which are spared by cherry fruit flies from the outset as far as possible. Simply because at the time the fruits of these trees are long past this stage of maturity. Early cherries are therefore much less susceptible to infestation by cherry fruit flies than the normally flowering or the late cherry. So if you want to plant a new cherry tree, it's worth thinking about planting a cherry tree.
Another point is the deliberate reduction in the size of the cherry tree. Be it through specific pruning of the tree or by choosing from the outset a base in which the cherry tree grows rather weakly. Thus, the fruit trees remain longer in size, which can be easily preserved with a corresponding insect protection net from access by cherry fruit flies.
Keep cherry fruit fly away from existing trees
There are different approaches. In any case, you should be sufficiently informed about the cherry fruit fly, if you really want to take effective countermeasures. One of the things to know, for example, is the fact that the twilled cherry fruit flies, once in the ground, hatch in late May - early June and then lay their eggs in the new cherries over a period of about 14 days, This is the period during which countermeasures against the cherry fruit fly must be taken. Anyone who takes measures against the cherry fruit fly much earlier, for example in the flowering of cherry trees, can not succeed - simply because the animals are not there at the time.
In the following, we would like to present some possibilities of combating the cherry fruit fly and briefly present the respective chances of success. Some advised measures are only suitable under certain circumstances - others can always be applied to any cherry tree.
❍ Yellow sheets as traps for the cherry fruit flies
The cherry fruit fly is magically attracted to the color yellow. No wonder, she usually puts her eggs in the cherries when they turn yellowish to light red. Who in the main flight of the cherry fruit flies so-called yellow sheets (e.g.available here) on the south side of its cherry tree, will soon have occupied the places provided with glue the yellow boards with cherry flies. That definitely deters a lot from the pests of your tree - but not all, as a rule.
Only with really small cherry trees can it be enough to hang yellow boards in the tree and let the cherry fruit flies die on them. For larger trees, yellow tablets are the best indicator of how many cherry fruit flies are traveling this year and whether the time of their activity has already begun. In addition, further measures must be taken here.
❍ insect nets to protect against cherry fruit flies
Also a means that is suitable only for smaller trees or for sections of a cherry tree: Protecting the fruits using a corresponding network. Nets, which are suitable for the protection against the cherry fruit fly, can be found in every hardware store with a good garden department. However, one must make sure that the stitches are not too broad. The mesh size should not be more than 1.8 mm - in some fruit farms even nets with a mesh size of less than 1 mm are used (for example, available here). With wider holes in the net, there is a risk that the cherry fruit fly simply slips through the mesh and still lays its eggs in the cherries. By the way, the net is also a good protection against stare.
As mentioned, such a network is ideal for smaller cherry trees. With old tree stands, which sometimes exceed the height of a house and have very bulging branches, it will be difficult to protect the entire tree crown with a net. Here, it is worth protecting smaller parts of the tree with such a network - the amount of cherries hanging on the protected areas is often sufficient for consumption in your own household.
❍ Prevent pupation due to larger documents
The maggots of the cherry fruit fly fall either from the eaten cherries on the ground or fall together with the cherries from the tree and then crawl into the ground. There they pupate and finally wait for the next year to lay their eggs in the new cherries again as cherry fruit flies. If you want to make sure that as few cherry fruit flies as possible roam the home garden the following year, there is an easy way to make sure of that.
Place a tarp or fleece under the cherry tree so that all falling cherries and all maggots that fall to the ground do not come into direct contact with the earth, but end up on this broadly laid out surface. Then you sweep at least once a day, what has collected on the surface together, throwing maggots and fallen fruit in a transparent and tightly closed trash bag and leaves it in the sun. The resulting heat kills the maggots and the contents of the bag can be added to the compost after a few days.
Even safer and associated with significantly less torture for the animals, it is to dispose of fallen fruit and fallen maggots directly in the bio-ton. This will significantly reduce the cherry fruit fly population in their own garden, and next year may assume that yellow traps are sufficient to protect most cherries from infestation of the cherry fruit fly.
Fight infestation of the cherry fruit fly
Some cherry lovers are disgusted when they open a cherry and a maggot crawls through the pulp. Others say that this is a completely natural process, and ultimately a maggot infestation is a sign that no unnecessary chemistry is used in the garden. Nevertheless, you do not necessarily want to eat the made of cherry fruit fly.
There are not many ways to relieve cherries infected with maggots. Of course you can open each of the cherries, remove the maggot and the core and then eat the pitted cherry. That is quite complicated.
❍ Take a bath of waterThe only real alternative is a water bath of cherries. When cherries are in the cold water for more than ten minutes, they begin to absorb the water. When cherries are soaked in water, it is anything but pleasant for the made in the cherry - the result is that the grub leaves the cherry. After a short time you will see a lot of small maggots swimming on the water surface. You can skim these and throw them into the bio bin.
However, one has to say of course that with this method, not all cherries are really worm-free or maggot-free. Some maggots are more persistent than others and just stay in the cherry. There is no such thing as a true patent remedy here. But if you do not want to throw away the whole crop, it's definitely worth trying. The success is more than 75 percent.
If the cherry tree is infested with cherry fruit flies, that's nothing to just settle for. There is a whole range of ways to get rid of the cherry fruit fly and its maggots.
