In the UK, the most common species include the Common Wasp and the German Wasp. While they play a crucial role in controlling other insect populations, wasps can become a nuisance, particularly in late summer when their colonies reach peak numbers.
They are known for their aggressive nature when disturbed and can deliver painful stings. The stings can sometimes cause allergic reactions.
Identifying wasps
Wasps and bees are often mistaken for one another, but there are key differences. Wasps have smooth, slender bodies with a more defined waist. Bees are more rounded in shape and stockier with thicker waists.
Wasps are bright yellow with black markings. Bees tend to be more brownish with a fuzzy appearance.
Unlike bees, which lose their stinger after one sting, wasps can sting multiple times, making them more of a threat when disturbed. Bees are essential pollinators and are generally non-aggressive and docile unless provoked, whereas wasps can be more territorial and aggressive.
Identifying active wasp nests
Wasp nests are commonly found in attic spaces, wall cavities, sheds, trees, and under roof eaves. They are made of chewed wood pulp which gives them a papery texture. An active nest will have a high volume of wasps flying in and out, particularly during the day. The entrance will be busy with wasps coming and going.
An old nest will appear abandoned, with no wasp activity. Wasp nests only last a single season and are not reused, so if a nest remains from a previous year, it will not become active again.
Seasonal wasp activity
Wasps follow a seasonal life cycle that influences their behaviour and the likelihood of coming across them.
Spring (March to May)
Queen wasps emerge from hibernation and begin building new nests. This is the best time to spot and remove small nests before they grow.
Summer (June to August)
Colonies are at their peak, with thousands of worker wasps foraging for food. Wasps become more aggressive during this time, especially in late summer.
Autumn (September to October)
As food sources dwindle, wasps become more persistent around sugary drinks and food. They also become more aggressive as the colony starts to die off.
Winter (November to February)
Most wasps, including the colony workers, die off. This leaves only new queens hibernating until spring. Old nests will not be reused.
Preventing a wasp infestation
To reduce the risk of a wasp infestation, follow these preventive measures:
- Keep food and sugary drinks covered when outdoors as they attract wasps.
- Seal bins tightly and dispose of food waste properly.
- Inspect your property for signs of early nest-building particularly in sheltered areas.
- Block potential entry points around your home, such as gaps in walls, vents, and roof spaces.
Treating a wasp sting
A wasp sting can be painful and cause redness, swelling, and irritation. While most stings cause mild reactions, some people may experience severe allergic reactions. Here's what to do if you are stung by a wasp:
- Immediate First Aid
Wash the affected area with soap and water to reduce the risk of infection. Applying a cold compress or ice pack wrapped in a cloth can help reduce swelling and numb the pain. - Pain relief
Over-the-counter painkillers such as ibuprofen or paracetamol can help manage discomfort. - Avoid scratching
Scratching the sting site can increase irritation and the risk of infection. - Watch for allergic reactions
Symptoms of an allergic reaction include difficulty breathing, swelling of the face or throat, dizziness, or a rapid heartbeat. If any of these occur, seek emergency medical assistance immediately. - For known allergies
If an individual has a history of severe allergic reactions to wasp stings, they should carry an epinephrine auto-injector (such as an EpiPen) and use it as directed in an emergency.
