Bees are common in all of the Netherlands. Usually these are the so-called honey bees (Apis mellifera L.). These honey bees are very useful for the cross-pollination of plants and cultivated plants. After all, the food of the bee is pollen and nectar of flowers. Flying from flower to flower, they provide the cross pollination. The collection of honey in particular is an activity of which humans benefit greatly.
The queen produces the offspring. Once enough young queens have developed in the nest, the old queen leaves the nest with part of the bee population, to look for a new home. The entire bee population, with the exception of the males, remains in their hive/nest throughout the cold winter months. In the fall, the males are killer or chased out of the hive. That is the period in which no fertilization takes place, causing the men to be obsolete.
The bee population lives in colonies and can house themselves in the most unlikely places. When you find a swarm, the best thing to do is to call EWS, which will remove and relocate the entire nest, where possible. Only when this is not possible and the bees cause nuisance, insecticides are used. In principle, bees are not dangerous to people. They will defend themselves however when attacked.
The professional exterminator of EWS will come to your home and will check what treatment will be most effective. Based on this diagnosis, he will treat the nest. You will be given the guarantee that the nest is treated in a responsible manner and that this treatment works.
