How Long Does Professional Wasp Nest Treatment Take in Birch?

A few wasps on day two are very often stragglers rather than a sign that the nest is carrying on, and there are clear ways to tell the difference.

Who the stragglers are

By the second day, the main burst of activity has usually passed, but a few wasps are often still around. These are stragglers: foragers that were away on the day, or wasps from the nest that did not return straight away. They may hover at the old entrance, circle and land, or wander on the ground nearby.

Seeing them is normal. A nest is not a switch, and the activity fades gradually. The point to check is whether the numbers are falling day by day.

For someone in Birch looking at the old entrance and worrying, a few wasps are not evidence of failure.

It helps to remember that a colony includes wasps at different jobs. Some collect food, some collect water, some build. Those away at the time of treatment come back in their own time, which is why stragglers appear on day two.

They are not a sign that a new nest has started, nor that the old one has recovered.

How stragglers behave

Stragglers behave differently from an active colony, and the difference is easy to learn.

• They hover or wander rather than travelling in a steady line.
• They often seem hesitant or disorientated near the entrance.
• They land on walls and the ground more than they enter the hole.
• Their numbers fall from morning to evening and from day to day.

An active nest, by contrast, has purposeful traffic in and out, with wasps carrying on as they did before.

Another difference is the time of day. Active colonies are busy through the warmest hours, while stragglers tend to appear in bursts and then disappear. If the entrance is quiet for half an hour and then a few turn up, that fits a straggler pattern.

The overall trend matters more than the detail.

Look at what the wasps are carrying. A wasp that enters with a pellet of material, or exits with a load, is working. Stragglers are rarely seen doing either. This is detail you can only judge from a good distance, so use a phone zoom, not your feet.

If you cannot tell, do not worry. The count over time is the main thing.

A quick comparison

If you are unsure, compare what you see with what you saw before the visit. If the traffic was a constant stream and is now a handful, that is a big change. If it looks much the same, that is when to call.

Pay attention to direction. Wasps coming out and flying away in a purposeful line are foragers on their way somewhere. A cluster that keeps landing and lingering is more likely to be the tail of the nest.

Remember that warm weather brings more wasps out, so compare similar times of day.

Keep notes in simple form: “morning, about six; evening, about three”. A short table on a scrap of paper is plenty. When you ring, you can say what the figures were without trying to remember.

If the figures are rising, ring at once. If they are falling, wait another day.

Some people find it helps to compare day two with day one in a simple way: “busier”, “the same”, “quieter”. That is all the business needs to hear. If the answer is “quieter” on the second morning, you are very likely on the right track.

If the answer is “the same”, give it until the afternoon, and then ring.

What to do about stragglers

Very little. Keep your distance, avoid swatting, and do not block the hole. Stragglers are drawn to food and drink, so keep these covered.

1. Watch from a window.
2. Note the count morning and evening.
3. Leave the entrance and the nest alone.
4. Report it if the count is not falling.

If a straggler lands on you, brush it off calmly. Sudden movements invite stings.

Stragglers sometimes try to enter the house, particularly if the old entrance is near a window or vent. Keep the nearest windows shut and check vents. A wasp at a window is often looking for a way out rather than in.

Think about where the stragglers can do harm. Garden tables, open bins and sweet drinks all attract them, so keep these under cover. A glass of squash left on a table is a death-trap for a wasp, and a hazard for the person who picks it up.

Check drink cans and bottles before drinking, particularly on a warm day.

When it is more than stragglers

If, by the end of the second day, the activity is much as before, or wasps are coming into the house, that is the time to ring. Give a clear account, including the times of your observations.

Do not wait a week and hope. A nest that is still busy is best looked at promptly.

Late in the summer, wasps from other nests may also visit your garden, so a few wasps at the old entrance can be unrelated to the nest. If there is no steady traffic, it is probably nothing to worry about. If you are not sure, ring and describe it.

Remember that the business can only help if it knows what you are seeing.

Be wary of any urge to take a spray to stragglers. Spraying near the old nest or entrance can disturb wasps and may create more problems than it solves.
