How attractant traps work
In the case of glue rings and glue boards, they'll do the job Pests literally on the glue. The inventors have copied the way they work from nature: pheromone traps, for example, contain synthetic sex attractants that stimulate the The odor signals of the females ready to mate are reproduced - quite typical of the species, so that you can only target certain insect species with them can catch. These traps attract the males, which then stick to the glue. The females, on the other hand, wait in vain for mating and accordingly cannot lay eggs. In this way, the infestation can be well limited, although with an ever-new influx of males, hanging up attractant traps is of course not sufficient.

What types of attractant traps are there
In addition to the pheromone traps, color tables are also used in fruit growing, which work according to a principle similar to that described above. The only difference is that the animals here do not react to sexual attractants, but to certain colors. Color boards coated with glue are hung in the tree, while glue rings are hung between September and mid-September March on the trunks of the fruit trees and on their stakes (pests such as the females crawl here too the
Frost wrench high!). Rings of glue catch the animals before they can even lay eggs.Overview: You use these attractant traps in the event of a pest infestation

Attractant traps are not a substitute for treatment
The attractant traps described cannot completely combat a pest infestation, but only limit it. In addition, they are mostly used to check whether and how strongly a certain type of insect actually flies towards the tree. Therefore, in addition to attaching glue rings and boards, you need to take other measures:
- Pests that are clearly visible on the tree must be removed at an early stage.
- This is done, for example, by reading, wiping, crushing, brushing or hosing down with a powerful jet of water.
- In the case of a strong infestation, often only one helps Cut back.
- Syringes The tree with a self-made plant manure, which is also effective against pests.
