ASIATIC HORNET CRISIS. No region will be spared even north of the Loire and this is getting worse every year. Their progress now reached Belgium and the Netherlands.
By studying the life cycle of this hornet, we realize that we can act very effectively and individually against the scourge. Indeed, nests built in the year are emptied of their inhabitants in winter because all the workers and males do not survive the winter and die. Only queens and young queens hibernate, in hollow trees, under piles of leaves, holes in walls etc.
They do not come out before February and resume feeding, it is at this moment that we can act, by having in our gardens traps to catch these future founders of nests. 1 Queen = 2 000 to 3 000 individuals.
To make traps, simply collect plastic bottles of mineral water, then drill three holes on the bottle, and fill within 10 centimeters of a mixture of 1/3 of dark beer, 1/3 white wine (to repel bees) and 1/3 of blackcurrant syrup. Just leave these traps in place from mid-February to late April. You can of course extend the operation until the arrival of cold weather.
Change the mixture occasionally and ensure wasps are dead. Thank you for reading and making your traps!
This is the kind of 'before and after' story that is hard to imagine can be effected in one summer. The last of the vegetable group meetings was able to witness at first hand what was achieved by Meryl and Bob.

Although most pine processionary moths (Thaumetopoea pityocampa) only live one year, some in high altitudes or more northern areas may survive for over two years. The adult moths lay their eggs near the tops of pine trees. After hatching, the larvae eat pine needles while progressing through five stages of development. Initially silken nests are built over the winter, then around the beginning of April, the caterpillars leave the nests in the procession for which the species is known. They burrow underground and emerge at the end of summer. High numbers of adults are produced in years with a warm spring.
