Wasp, Hornet and Bee Species

(Family: Vespidae, e.g. Vespula Vulgaris & Vespula germanica)

These are the two most common wasp species in the UK and the ones responsible for causing painful wasp stings. Once indoors, they prefer to build nests in sheltered locations with easy access to the outside, such as lofts, garages and wall cavities. Outside they may nest in old rodent burrows, hollow trees and bushes.

The Common Wasp (Vespula vulgaris) and the German Wasp (Vespula germanica) are widely recognised due to their bright yellow and black markings, which make them easy to identify around homes and gardens. Their social colonies can grow rapidly in summer, leading to increased encounters with people, especially in outdoor areas where food and sugary drinks attract worker wasps towards the end of summer.

These wasp species are particularly active from late spring through autumn, with workers becoming most aggressive towards the end of summer when natural food sources decline. Therefore, recognising signs of wasps nests, their nesting habits and preferred environments is essential for ensuring safe wasp control and minimising the risk of accidental stings around UK properties.

The European hornet is the UK's only native hornet, widespread across England and Wales. Measuring 25–35mm, these "gentle giants" are larger than common wasps and identifiable by their reddish-brown thoraxes, yellow-and-black abdomens, and dark legs. Active from May to November, they are beneficial predators that hunt garden pests like beetles and flies, typically nesting in hollow trees, hedgerows, or quiet lofts.

The native European species is more docile than wasps and is less prone to sting unless its nest is directly threatened. Because European hornets provide natural pest control and are vital to the ecosystem, nest treatment is generally discouraged. However, any sightings of the smaller, invasive Asian hornet should be reported immediately to the National Bee Unit to protect native pollinators.

(Apis mellifera)

Honey bees are the species kept by beekeepers. If you have a problem with them on your property, contact a local beekeeper or Environmental Health Department as they may be able to arrange for the swarm to be relocated. Unlike wasps, honey bees are not naturally aggressive and rarely pose a threat unless their nest is disturbed.

They play a critical ecological role by pollinating many of the UK’s fruit and vegetable plants, thus supporting biodiversity and agricultural production. Because their populations are currently under threat from factors such as the varroa mite and habitat loss, it is important to avoid harming honey bees. Correct identification ensures these beneficial insects receive proper protection and management; so, always seek expert advice if you suspect a honey bee nest or swarm on your property.

As their name implies, Solitary bees live alone but nest near each other in villages in suitable nesting areas. Unlike honey bees or wasps, solitary bees do not form large social colonies; instead, each female constructs and provisions her individual nest, often choosing bare ground, sandy soils, or gaps in old brickwork and mortar.

These bees play an important role as pollinators, helping to support healthy ecosystems and productive gardens across the UK. While they may appear similar to other bee species, solitary bees are typically non-aggressive and unlikely to sting, making them safe around homes, gardens, and play areas. Their presence is a strong indicator of local biodiversity and healthy soil, as they prefer undisturbed, sheltered locations. Encouraging solitary bees by providing bee hotels and maintaining natural nesting habitats can enhance garden pollination and benefit native plant species.

(Osmia sp.)

Mason bees are also known as masonry or mortar bees because they like to nest in crevices or holes in masonry. They prefer to stay near walls that receive sunshine for much of the day. Mason bees use naturally occurring holes in bricks or mortar joints (especially mortar with a high lime or sand content). These bees play a vital role in pollination, supporting both wildflowers and agricultural crops throughout the UK.

Unlike social bees, they are solitary; each female mason bee creates and provisions her own nest, resulting in little to no aggression towards people or pets. Their activity tends to peak in spring, which coincides with the flowering of many fruit trees, making them exceptionally efficient pollinators. Encouraging mason bees in gardens by installing bee hotels or preserving existing wall habitats can enhance pollination and boost biodiversity, while posing minimal risk due to their gentle nature and reluctance to sting.

(Bombus sp.)

Bumblebees are often confused with honey bees. However, bumblebees are generally larger and have a more robust, stocky frame with a distinctively furry appearance that helps them withstand cooler temperatures. Their bodies tend to be rounded and covered with dense, soft hair, often displaying black coloration interspersed with bands of yellow, orange, or even white, depending on the species—unlike honey bees, which are slimmer and have a more uniform brown or golden tone.
