If the leaves of the fruit trees are eaten in the spring, then mostly frostbird caterpillars are to blame. Here are 3 tips on how to fight the frost tension caterpillars.Antifreeze caterpillars damage fruit trees
Antifreeze caterpillars damage fruit trees
First and foremost, it is the little frost tree that is in the garden, mostly on fruit trees, berry plants and deciduous trees.
It is therefore advisable to take preventive measures, especially in spring, to combat this pest in good time.
Incidentally, an infestation of the plants is recognizable through holes in the still fresh spring leaves or a partially even complete gnawing of the same.
Frost tensioners lay eggs in winter
Basically, you should know that the little frost tensioner usually deposits its barely visible red eggs near the flower buds in winter. As soon as the buds break open, the relatively voracious caterpillars hatch and immediately attack in large numbers on the flowers, later even on the young fruits. This in turn means that the autumn harvest is very small. In the case of an infection, you often have to expect a total failure.
Especially since the caterpillars pupate in the ground again in June and fresh moths hatch in October. The cycle then begins again.
Fighting frost tension caterpillars - 3 tips
There are various measures to combat the little frost tree in the garden. Of course also in a natural way, for example by attracting the great tit in your own garden, e.g. by setting up nesting boxes. You can also keep free-range chickens near the fruit trees.
Another possibility is that in summer (from approx. September to the end of October) you apply the most color-intensive glue rings around the fruit trees, to which the flightless females of the small frost tensioners stick and are caught on the way to the egg laying.
Such glue rings are e.g. available in specialist shops and should cover the tree in as flat a position as possible - possibly remove the bark carefully beforehand. This has the advantage that the females are not given any hatching opportunities.

The specialist trade also has a special pesticide ready for you to spray on the plants in early spring. This then prevents the caterpillars from hatching.
It is best to get advice from a specialist retailer. This is the only way to be sure that you are fighting the frost tension caterpillars with the right pesticide.
