September & early Octoberĭuring September and October, all the queens leave their nests to look for a location to hibernate over the winter. The workers are responsible for finding enough food for the hibernating queen, and this can trigger aggressive behaviour. The eggs have hatched, and the young queens leave the nest to mate and find a suitable hibernation home before the winter. Wasp activity is most evident in high summer, heading towards September. Most people recover quickly from a summertime sting, but sometimes, there is a more severe reaction ranging from localised swellings called hives to anaphylactic shock in rare cases.Īlways check that it’s a wasp’s sting before moving forward with treatment. However, many homeowners will destroy a nest if discovered to avoid an infestation of wasps later in the summer. However, scientists have increasingly begun to realise that wasps are also pollinators when they land on flowers to drink nectar. Wasps are essential to the ecosystem, destroying pests like caterpillars and greenflies. This is the time of year when wasps become evident, partly due to numbers but also because they're keen explorers of their surrounding landscape. Workers are looking for food and nesting materials. June and July are the months when a wasp colony becomes active. The queen wasp lays eggs to create workers, drones, and new queens. Aerial locations are prime wasp property, which is why many people find them in the loft or roof of a shed or garage. Wasp nests can appear almost anywhere, in dense bushes, holes in the grounds, and the eaves of buildings. What Time of Year Are Wasps Most Active in the UK? April & MayĪround the beginning of April, a queen wasp emerges from hibernation and searches for locations to create her nest. However, conditions have been optimal in other years, and wasp numbers increased. There were fewer wasps and other insects in the UK heatwave in 2022 due to a lack of food sources. ![]() The pattern of the seasons and the UK weather dictates how active wasps are. Nests can begin the size of a golf ball but grow to something more akin to a football by the end of the season. Wasp nests usually last between three to four months over the summer period. Wasps can plague specific properties, whereas other people may be unaware they have even had a wasp colony until they discover the empty nest later in the year. Wasps like warm weather, so a cold, wet spring will delay their arrival, and a mild, temperate autumn can encourage the queens to remain active into October. In the UK, the wasp season usually begins around April and ends in September. ![]() ![]() Instead, they play an essential role in the ecosystem and may even be a gardener’s ally. In this article, you'll discover the lifecycle of a wasp and learn how they’re not necessarily the enemy. However, when they appear varies from year to year, depending on the good old British weather! Wasps like warm weather, so their lifecycle tends to follow the spring/summer calendar. However, this is beginning to change with the alteration in the traditional pattern of the four seasons in the UK. The plague and pest of outdoor meals and picnics, these insects have a seasonal lifecycle. Wasps are associated with summertime in the UK.
