When Is Wasp Season in East Keswick?
The common mistake is assuming wasps simply arrive in August; in fact a colony has been growing since spring, and understanding how it grows explains why the peak feels so sudden.
Why August seems to come out of nowhere
People often say the wasps “appeared overnight” in August. The mistake is to think of wasps as arriving, when they have actually been multiplying out of sight for a quarter of a year. The change you notice in August is the final stage of a steady build-up, not a sudden invasion.
Understanding that build-up is the most practical thing you can do, because it tells you when a nest is easy to deal with and when it has become a serious matter. It also takes away some of the mystery: wasps are not following you around, they are leaving a nest that has become very large.
This guide traces the growth of a single nest from first cell to full colony, with a short checklist at each stage. It is written for households and businesses in East Keswick and the neighbouring villages, though the pattern is the same anywhere in the country.
Stage one: a single queen and a handful of cells
The sequence starts in spring. Wasps start building nests from late April, depending on the weather and on how mild the spring is. A queen picks a sheltered spot, such as a gap in the eaves, a wall cavity, a chimney, a tree, a bush or a hole in the ground, and begins a small nest by herself.
At this stage the nest is tiny and the traffic is one insect. It is almost impossible to notice unless you happen to be looking at the right place at the right time. If you do see a wasp returning repeatedly to one small gap in April or May, you may be watching the beginning of the colony.
- Note the spot and the date.
- Check it again every few days to see whether activity increases.
- Do not block the gap or disturb it.
Stage two: the first workers
After a few weeks, the first workers emerge and take over foraging and building. From this point the queen no longer needs to leave the nest, and the colony begins to add more wasps with each round of eggs. Growth is slow at first and then accelerates, because every new worker helps to rear the next lot.
In late May and June, the signs are still modest, but they are more consistent. The same gap now shows regular comings and goings through the day, and you may spot wasps carrying pieces of wood fibre, which they chew into the papery material of the nest.
- Watch for a steady stream rather than the odd visitor.
- Notice whether wasps return at roughly the same height and angle, which suggests a fixed entrance.
- Keep windows nearby closed if wasps are getting indoors.
If you decide to book at this stage, the nest is much smaller than it will be in six weeks’ time.
Stage three: rapid growth in July
July is when the colony’s growth really shows. The nest has been extended many times over, and the number of workers rises with it. They need food, so garden activity picks up around bins, fruit, barbecues and outdoor tables. Householders often report that wasps have become a nuisance indoors, flying to windows and light fittings.
This is also the stage where people first feel they ought to do something. A few suggestions on what to do and what to avoid:
- Do keep a note of where the wasps appear to be heading.
- Do keep children and pets away from that part of the property.
- Do not use anything to try to destroy the nest yourself.
- Do not stand near the entrance to watch.
The nest is now large enough that a disturbance will bring out a defensive response in numbers.
Stage four: the peak and what it means for safety
By August, the colony is at its peak. A nest can hold 2,000 to 10,000 or more wasps, and the number of foragers means you meet them everywhere: at the bin, at the back door, on the washing and over the drinks. None of this means the wasps have changed their nature. It means there are more of them, with more mouths to feed.
It is worth saying plainly that the biggest risk in August is not the wasps you can see but the nest you cannot. A colony in a wall cavity or under a roof tile can be sending out a great many flights each day without anyone realising where they start. If you have seen more than the odd wasp indoors, look for the entrance before you assume the cause is open windows.
Safety comes down to a handful of rules. Stay away from the nest, and keep others away. Do not swat wildly, as this tends to provoke more attention. Cover food and drink. Keep doors and windows closed near the nest.
If anyone in the household is allergic to wasp stings, they should speak to their GP about what to do, and you should tell us at booking so that it can be taken into account. For an ordinary sting, wash the area, take out the sting if visible and use a cold pack. Call 999 for swelling of the face, lips or throat, wheezing or difficulty breathing, dizziness or a widespread rash.
