From midsummer onwards, such a procedure carries a high degree of risk. In the autumn, yellow jackets lose their aggression, become sleepy and slowly say goodbye to life.
In the spring, however, the queen spends all her energy building a nest. All operations against yellow jackets must be carried out late in the evening.
Although yellow jackets never sleep, their activity decreases considerably at night. After sunset is the best time to destroy a yellow jacket nest.
When the sun goes down, all yellow jackets return to the nest and you have the chance to destroy all individuals at once.
When fighting yellow jackets be sure to use protection for your face and skin, as yellow jackets stings are very painful and can cause serious consequences.
