When Is Wasp Season in Rotherham?

As autumn arrives the colony slows, but wasps can stay troublesome for a while, so this guide looks at the end of the season and what to do about it.

The season does not end on a date

Ask when wasp season finishes and you will not get a calendar answer. Colonies peak in August and decline as the year moves on, but the change is gradual and varies with the weather. A mild September can feel very like August, while a cold snap can empty a garden in days.

What you can say is that the second half of the season has its own character. The colony is no longer growing, the nest has done most of its work, and the insects behave differently from the busy workers of midsummer.

In Rotherham, as elsewhere in South Yorkshire, households sometimes assume that once the nights draw in, the wasps are gone and nothing needs doing. That is not always the case, and a little attention in autumn pays off.

What wasps are like in late season

In the weeks after the peak, wasps are often more noticeable than ever around people. With fewer jobs inside the nest, many turn to sweet food and drink, and that is when they gather at cafés, cans, fruit and bins.

• They can seem more persistent, returning again and again to the same drink.
• They are often found around fallen fruit and sugary spills.
• A nest may still have plenty of wasps in it, even when the numbers outside appear to fall.

Stings are as likely in October as in August if someone disturbs the nest, so the usual caution applies. Keep away from the entrance, and do not assume a quiet-looking nest is empty.

Another thing to remember is that cooler days do not make wasps harmless. A wasp on a chilly morning may be slower, but it can still sting, and a person who brushes against a nest on a cold day is no safer than on a hot one.

Should you leave a nest to fade out?

It is a fair question, and the honest answer is that it depends on where the nest is. A nest at the far end of a large garden, away from paths and doors, might be left alone with everyone keeping clear. Many households are comfortable with that.

If the nest is near an entrance, a washing line, a play area or a window, waiting is a poorer choice. The colony may take weeks to decline, and each week is another chance of a sting. Treatment is available at the same fixed price however late in the season it is.

Whichever you choose, do not try to speed things up yourself. Poking, spraying or blocking a nest is as hazardous in October as it is in July.

Think about what the nest is doing to your routine. If you have stopped using a door, avoided the washing line or kept the children off a patch of lawn for weeks, the nest is already costing you something. Many people find that treating it and getting the use of the garden back is worth far more than waiting for nature to take its course.

After the wasps have gone

Once a nest is quiet, whether through treatment or the end of the season, there are a few sensible things to do. Ask the technician whether the empty nest can be taken down, and whether the gap it used should be repaired.

1. Wait until you are sure activity has stopped before touching anything.
2. Ask a professional about taking down the empty nest, especially if it is high up or inside the structure.
3. Have gaps in eaves, walls and roof edges looked at by a builder or roofer, so they are less appealing next spring.
4. Clear away old nest material from sheds and outbuildings with care, avoiding contact with any wasps still present.

Repairs done in autumn mean fewer sheltered spots when the new season starts in early April.

It is natural to want to clear away a nest the moment it looks inactive. Resist that urge. A nest that looks empty from outside can still have wasps inside, and sweeping it off a wall with a broom is how people get stung in October.

Looking ahead to next year

Winter is a quiet time, and it is a good moment to think about prevention. Make a note of where nests appeared, keep bins and compost tidy, and plan a spring walk round the property so that any new nest is found when it is small.

Nothing guarantees that a spot used one year will or will not be used the next, so treat any such record as a prompt to look rather than a prediction.

Garden jobs are worth a thought as well. Pruning hedges, clearing sheds and lifting turf are all things people do in autumn, and each can disturb a nest that has gone unnoticed. If you have seen wasp traffic anywhere near the job, hold off until it has been dealt with.

If you need help with a late nest

The Wasp Exterminator charges a fixed £70 per nest, with an additional nest at the same property at £25 extra. There is no call-out charge, and the service is open seven days a week with same-day visits offered for homes and commercial premises.

Technicians are fully insured and qualified. You will be told the price over the phone before anyone comes out, and it might be higher where a nest needs special access equipment. To arrange a visit, phone 07798 792 774 or use the online booking form.

If a technician has treated your nest, ask for advice on when it is sensible to go back to the area, and whether anything should be done to the gap. You can raise these questions at the time of booking, so the answers are ready.
