When Is Wasp Season in Baldock?
A month-by-month guide to the wasp year, from the first queens in spring to the August peak and the slow decline in autumn, with simple checks for each stage.
The short answer: spring to autumn, with August the busiest
Wasp season does not have a single start date. It builds. A queen begins a nest in early April, depending on the weather and how mild the spring has been, and the colony grows through the summer until it reaches its peak in August. By then a single nest can hold as many as 2,000 wasps. After that the numbers fall away as autumn arrives.
If you are in Baldock and wondering whether the wasps you can see right now are a problem, the calendar below should help you judge it. The same pattern applies to most of the UK, so the advice is useful wherever you live.
It helps to think of the year in four stages rather than one season: the quiet start, the build-up, the peak and the decline. Each calls for a slightly different level of attention, and the sections below take them in turn.
April and May: the quiet beginning
In the first weeks a queen works alone. She chooses a sheltered spot, often a gap in the eaves, a wall cavity, a chimney, the inside of a shed, a bush or tree, or an old hole in the ground, and builds a small nest the size of a golf ball or a little larger. Few people notice it at this stage.
What you may see is a single large wasp inspecting the soffits, the roof edge or a gap in brickwork. That is worth a glance. One wasp coming and going from the same spot day after day usually means a nest has started.
This is the easiest time to act, because the colony is tiny and the nest is easy to reach. A treatment is still a fixed £70 whenever it happens, but an early nest is far less likely to need anything awkward.
Early nests are also the ones most likely to be found by accident, while you are doing something else. Opening the shed for the first time since winter, taking the cover off the barbecue or lifting a bin lid are all moments when a small nest or a flying queen turns up.
A habit worth forming is to glance at the same few spots each time you walk past: the corner where the roof meets the wall, the top of the garage door, the base of the hedge. Patterns are far easier to spot in a place you look at regularly.
June and July: the colony grows
Once the first workers hatch they take over the building and feeding, and the queen stays inside laying eggs. From here the nest expands quickly. Traffic at the entrance goes from the odd wasp to a steady stream, and you may hear a faint scratching or buzzing from a wall, ceiling or loft.
Things to look for during these two months:
- a regular line of wasps flying to and from one small gap
- a paper-like grey material around a vent, airbrick or fascia
- wasps crossing the garden along the same route every day
- a buzzing that gets louder when the day warms up
Do not block a hole you suspect is an entrance. Trapped wasps can chew through plaster or find their way into the house instead.
The change from spring to summer is when many people first hear the nest rather than see it. In a quiet house at night, a soft rasping noise from a wall or ceiling can be the colony chewing and building. It is easy to put down to pipes or the building settling, so if the noise follows the warmth of the day, take it seriously.
Wasps from a nest high up are not always obvious from the ground. Standing back and looking up at the roofline for a few minutes on a warm afternoon will usually show whether anything is flying in and out.
August: the peak
August is when nests are at their largest and when most people first realise they have a problem. The colony has reached full strength, and the wasps are far more noticeable around gardens, bins and anywhere food is eaten outside.
The nest is also at its most defensive. Wasps will swarm and sting if they feel threatened, so keep children and pets well away, avoid mowing or strimming near a suspected nest, and do not throw things at it or try to knock it down.
If you find an active nest in August, book a treatment rather than waiting for it to go quiet by itself. It will not do so for weeks, and it may be near a door, a washing line or a play area in the meantime.
Because August is peak month, it is also the time when the most calls are made. Bookings are taken seven days a week, with same-day service offered, but it still helps to call as soon as you are sure of what you have seen rather than waiting for a weekend.
Nests do not all behave in the same way. Some are tucked into a roof void and seem to cause no trouble for weeks, then wasps start appearing in a bedroom. Others are in the ground, and the first sign is a sting while mowing. Whichever it is, the advice is the same: keep clear, keep others clear and arrange a treatment.
September to November: decline and leftovers
As the weather cools the queen stops laying and the colony begins to die back. Surviving wasps become irritable and hunt for sugar, which is why you notice them at fizzy drinks and ripe fruit late in the season. New queens leave to shelter somewhere for the winter and start the cycle again next spring.
An old nest is not reused. If you find an abandoned one in the loft or shed after the first frosts, it is safe to leave, though it is sensible to check it is truly inactive before you touch it. Blocking the access point over winter reduces the chance of a fresh start in the same place.
To book a treatment, phone 07852 111 437 or use the online booking form. The technician is available seven days a week, with same-day service offered and evening and weekend appointments.
A practical end-of-season routine is to clear fallen fruit, empty and rinse recycling, and tidy any stored items in sheds and garages. If you take down hanging baskets or garden furniture for winter, check them for abandoned nests and dispose of them carefully once you are sure they are empty.
If you would like to know whether an empty nest can be taken down, ask the technician when you book. It is a simple question and the answer will depend on where the nest is.
