We all know that and surely everyone has held a madig apple in their hands at some point. If it was only in the hand, then that was the least of evils. Often you can see the maggots that bore into the apples but not and bite into the fruit with relish. Well, then you have a small meat side dish.
These maggots are the larvae of the codling moth, a moth that becomes active at night. The maggots get into the fruit because the females lay their eggs on the young plants. The maggots feed on the apples and burrow into the fruit. This can be avoided or at least curbed if, in addition to nesting cheeses and bird baths that should be set up in the garden, you also work with attractant traps that attract the male moths. This reduces the population and fewer females are fertilized and therefore fewer apples are infested.
