When Is Wasp Season in Pale Green?

A small nest and a full one are very different problems, so understanding how the colony grows explains the urgency.

The same nest, three sizes

People often ask whether a wasp nest is really a big deal. The answer depends on when you ask. A nest in May and a nest in August are not the same thing, even though they may be in exactly the same place. For anyone in Pale Green trying to decide how quickly to act, understanding the growth of the colony is the most useful piece of knowledge.

The sections below follow a typical colony through the year, with an eye on what each stage means for the people who live and work nearby.

Late April and May: golf-ball territory

A colony begins its nest from late April, depending on how mild the spring is. At the start, the nest is small, with a few wasps and a modest structure. It may be a gap in the eaves, a hollow in a wall or a hole in the ground. There are few wasps flying, and it is easy to miss.

The risk at this stage is low, in the sense that a disturbed nest produces a handful of wasps. It still stings, but the scale is small. It is also the stage at which treatment is simplest.

This is when it pays to look. A colony in its first weeks is at its most vulnerable, and if you notice and report it, you shorten the whole episode. The wasps that you might see are working constantly, so patience on a warm afternoon will show you where they go.

June and July: multiplying

Over these two months the colony grows rapidly. Each new generation of workers can build and forage, so the rate of growth increases rather than staying steady. The nest expands inside its cavity, and the traffic at the entrance rises. What was a trickle becomes a stream.

• Entrance activity becomes noticeable from several metres away.
• Wasps start to appear more often indoors and around bins.
• Vibrations near the nest provoke more reaction.

The risk of a swarm rises with each week, because there are more defenders.

One effect of growth is that the nest needs more space. If it is in a cavity, the wasps enlarge it by chewing away at the inner surface. That is why you may see more papery debris appearing outside, or hear scratching and rustling inside the wall.

Take time to compare how things look from week to week. A nest that appears larger in your notes each time confirms that the problem is real and growing.

August: the peak

At the peak, a nest can hold from 2,000 to 10,000 or more wasps. That is a very large number of insects to live in a roof void or a bank. Wasps that are threatened can swarm and sting, and with so many present, a swarm can be serious. Walking past the nest, mowing, or banging on the wall can set it off.

The wide range, from 2,000 to over 10,000, reflects how much nests differ. You cannot judge from the outside which end of the range a given nest falls into, so treat every nest as potentially large.

Another effect of size is that the nest becomes more difficult to approach safely. Even a technician takes more care with a large colony than with a small one, and a householder should take none of the risks.

Share what you learn with people nearby. If you notice a nest growing, a word to the neighbours may help them to check their own properties before it spreads to theirs.

September and October: the fall

As autumn comes, the colony declines. Numbers fall, though a nest that is still active remains a hazard. Late in the summer wasps seem keener on sweet food, so many of the encounters at this time occur away from the nest. Do not take a quiet week as proof that the nest is empty.

Remember that wasps seen at your table in late summer are not necessarily from the nest you can see. Some may belong to a nest elsewhere in the area. The line of flight is the clue.

It is worth remembering that wasps do not grow at the same rate everywhere. A sheltered, sunny spot may develop faster than a cool, shaded one, which is another reason to treat every nest as one that could be large.

What size means for you

The practical message is that the earlier you act, the smaller the problem. The cost of treatment is fixed, so there is no financial reason to delay, but there are strong practical reasons not to. A small nest is less dangerous to approach, less disruptive and less likely to have affected neighbours.

Whenever you find a nest, keep away from it, keep others away and book. Describe the position and how long you have seen activity.

Think of treatment as an investment in a quieter summer. The earlier you book, the less disruption the nest causes in between.
