How to Tell If You Have an Active Wasp Nest on Your Bocking Property

Evening is when many people notice a problem for the first time, and it is also when the wrong decision, such as shining a torch at a nest, is easiest to make.

The evening trap

Many householders think about wasps at the end of the day. They get home from work, take the washing in, or sit down outside, and a wasp is buzzing at a gap they had not noticed. It seems sensible to deal with it now, while the wasps are fewer, and a persistent myth says that wasps are asleep at night and can be tackled safely in the dark.

That belief is the cause of a lot of stings. Wasps do slow down as the light fades and the air cools, but a nest is never empty. Workers remain inside, tending the grubs and keeping the nest warm, and they respond quickly to light, vibration and heat.

What dusk activity looks like

As the evening cools, traffic at the entrance drops. The last few foragers come home, often heavily laden, and the flow eases to a trickle. If you watch quietly from a distance in the last hour of daylight, you may see a final burst of returns and then a lull. That in itself is a useful sign: wasps that stream home and then stop at the same gap are nest wasps.

• A cluster of returning wasps just before dark.
• A few wasps that stay at the entrance, perhaps guarding it.
• A hum that continues inside after the traffic has stopped.

What you cannot tell at dusk is how big the nest is. A quiet entrance does not mean a small colony, only a cool evening.

Notice the temperature as the evening goes on. On a warm summer night, a nest can stay surprisingly active, with some workers fanning at the entrance to cool the interior, and a faint hum may continue until well after dark. On a cool night, everything goes quiet earlier. Warm dusk activity is another reason not to assume the colony is asleep.

Why a torch is a bad idea

Shining a torch at a nest entrance or into a hole is a common reaction, and an unwise one. Light, and the heat that comes with some torches, can alert the guard wasps. Anyone who has been stung by a wasp after dark will tell you how far they follow a light.

If you must look, use the weakest light you can, and keep it pointed away from the gap. Better still, wait for daylight. A quiet look in the morning, in good light and at a distance, will tell you much more with far less risk.

Another danger of evening inspection is that you are working in poor visibility. You may not see the gap you are about to step in front of, or the ladder you are about to lean on. Tripping over a hose or knocking a plant pot near a nest is a classic way to cause a disturbance. If it is dark enough that you need a torch to see the ground, it is dark enough to leave the investigation until morning.

Some people also use the evening to carry out DIY solutions, such as spraying a household insecticide into a gap. Please do not. Sprays do not reach a nest in any dependable way, and the wasps that come out will be angry, in the dark, and between you and the door.

Wasps drawn indoors by lights

Evening lights draw wasps indoors. A lit window in a darkening room is a beacon, and a wasp already inside your house will fly towards it. If you find wasps in a room in the evening, with the light on, it can be hard to say whether they have wandered in through an open door or come from a nest in the structure.

Check if the numbers are consistent from night to night. A single wasp now and then is probably a stray. Several each evening, particularly in the same room, may be coming from a nest. Turn off the light, open the window a little on the side furthest from the wasps, and let them leave if you can do so calmly. Close the door of the room if you cannot.

What to do tonight

If you notice a nest in the evening, there is little to do except keep away. Close windows on that side of the house, keep curtains drawn and make sure children and pets are indoors. Note the spot as clearly as you can, and plan to take a calm look in the morning, from a safe place.

Do not seal the gap, even if it is dark and the wasps seem to have gone. Sealing a nest in overnight means the wasps will look for another way out by morning, and it might lead into the house. Do not spray or smoke it either.

It can help to plan a morning check. Choose a time when the sun is on the wall you are worried about, make a hot drink and settle at a window with a good view. Ten to fifteen minutes will tell you much more than a hurried look by torchlight, and you can write down what you see in comfort.

Remember also that dawn is cool, and activity builds slowly. If you look at six in the morning and see nothing, try again at nine or ten before concluding there is no nest.
