When Is Wasp Season in Herongate?

How busy a nest looks changes through the year, and learning to read that traffic tells you how far the colony has got and how urgent the problem is.

Traffic tells the story

You rarely see the nest itself. What you see is movement: wasps going in and out of a hole in a wall, a roof edge or the ground. That traffic changes through the year, and with a little practice you can read it to judge how developed the colony is. For a household in Herongate, it is often the clearest information available.

The clues are easiest to read from a fixed spot, so choose a place to stand where you can see the entrance without being under it. A window upstairs, a garden bench some distance away or a patio chair are all suitable, provided you stay still and keep clear of the flight path.

Late April and May: a trickle

At the start, depending on the weather, you may see just a handful of wasps. A single insect enters a gap, stays a short time, and leaves. Visits are sporadic, perhaps one every minute or so in the sunniest part of the afternoon. It is easy to dismiss.

The importance is not in the number but in the repetition. If the same gap is visited again and again, a nest is likely, and this is the easiest time to arrange treatment.

Weather affects how much you see. On a cool, grey morning even an established nest may seem calm, whereas a warm afternoon can double the traffic. Compare like with like by always looking at a similar time of day.

Take a note of the direction of the flight as well. Wasps usually leave in a particular line, and following it tells you where they are feeding. If the line crosses a patio or path, you know that is where encounters will occur.

June and early July: a steady stream

As the colony grows, the traffic becomes steady. In place of an occasional visitor, you see a regular line, with wasps leaving and arriving every few seconds. Some return carrying food or building material. The flight path becomes clear, and you can tell which direction they head.

• Note which way the line runs, as it shows where they forage.
• Count the wasps passing in one minute, then repeat a week later.
• Watch whether the entrance is widening or showing grey paper.

An increase in numbers confirms the nest is developing.

A few features can be helpful. Wasps arriving with something in their jaws are building or feeding. A steady flow in both directions suggests a nest in full swing. A concentration of wasps hovering near the entrance suggests that guards are on watch.

Do not worry about identifying every behaviour. The simple truth is that more traffic means a bigger colony, and a bigger colony means a bigger risk.

August: a crowd at the door

At the peak, the nest can hold from 2,000 to 10,000 or more wasps, and the entrance can look like a busy doorway. Guard wasps may hover near the opening and respond to anything that comes close. You may notice wasps flying out in numbers if someone walks near or if there is vibration.

This is the time to stay well back. Do not stand beneath the entrance, do not take photographs from close range and do not approach with a ladder.

If you must pass near the entrance, use a different route. Taking the long way round to the shed for a few weeks is an easy price to pay. Warn visitors and delivery drivers as well, because they do not know where the nest is and may walk straight beneath it.

Children and pets need a firm boundary. Tell them clearly which area is off limits and why, and keep gates closed if necessary.

If you have a rental or shared access, make sure the neighbours using the same path know about the flight line as well. It is easy for a tenant who has just moved in to walk straight past a nest that long-term residents have learned to avoid.

Finally, remember that your own observations are valuable. When you describe the traffic to the person booking your visit, mention the direction and the pattern, because it helps them plan the work.

September and October: a thinning line

As autumn arrives the traffic thins. The line breaks into occasional visitors and then perhaps a few stragglers on warm afternoons. A reduced flow does not prove the nest is empty, and cool weather can cause temporary quiet. Watch for several warm days before drawing a conclusion.

In the same weeks, wasps from the nest may spend time at sweet food, so you may see more of them at the table than at the nest.

Weather in autumn can fool you. A cold, wet week might suggest the nest has gone, only for a bright day to bring a handful of wasps back. If you are uncertain whether the nest is still active, describe what you have seen when you book.

Wasps at a late-season nest can be slower and less predictable, and a disturbed nest can still produce stings.

A quiet nest still needs attention

Beware of the idea that a quiet nest is a safe nest. An early-season nest is quiet because it is small, and it will not stay that way. A late-season nest is quiet because the cold slows it, and it may still contain wasps.
