Do Wasps Return to the Same Nest Every Year? A Guide for Barnsole Gardens
Not every wasp nest comes to anything, and a spring nest that goes quiet can seem like a puzzle, so it helps to know what may have happened.
The nest that went quiet
Perhaps you saw a queen going in and out of a gap in May, and then, after a couple of weeks, nothing. No wasps, no noise, no sign. It is natural to feel relieved, and equally natural to wonder whether the nest is still there and whether it will come back.
The first thing to understand is that early nests are fragile. A single queen is doing all the work at the start, and not every attempt succeeds. Some queens leave, some are lost, and some nests simply stall. What happens to the nest after that depends on whether anything is still alive inside.
The second is that nests are never reused. A stalled one is finished, and a fresh nest, if there is one, will be started by a different queen.
There is a further point worth bearing in mind. Wasps are not the only creatures to use gaps in buildings, and a quiet gap might simply have been abandoned by something else. The traffic you saw might not have been wasps at all, which is why a clear look at the insect is useful.
Do not be embarrassed about not knowing. Even people who deal with wasps often cannot say from a distance what a quiet gap means.
Why early nests fail
There are several possible reasons, and a household rarely knows which applies. A queen may have been disturbed or may have abandoned the site. Weather can interfere, and cold spells in spring make foraging hard. The first brood may not have survived to adulthood.
None of this is predictable, and you should not count on it. A quiet nest in spring may be dead, or it may be a nest that is simply quiet on a cold day. The only way to be sure is to look for signs over a period of time.
Do not assume that a small nest has failed because you saw nothing for a day or two.
Cold, wet spring weather can cut off a young nest’s food supply and make a queen stay inside. A nest that seems dead in a wet fortnight may be active again once the weather improves, so it is wise to look over several weeks before drawing any conclusion.
Telling quiet from dead
Observation is your tool, and patience.
- Watch the entrance for several minutes on a warm, dry day.
- Repeat on a different day.
- Note whether any wasps come and go.
- Listen for a faint hum from the cavity.
- If you see traffic again, treat it as a live nest.
A gap with no activity over a week of good weather is probably empty. Even so, do not block it until you are sure.
Mark your watch times in the diary. If you looked at noon on Tuesday and saw nothing, and looked again at ten on Saturday and saw traffic, that tells you a lot. Different days and different times are the best way to catch whatever is happening.
It is also worth thinking about what the nest was made of. A small starter nest is no bigger than a golf ball and is made of fine, pale paper. If you can see one that is empty, with the paper dry and the cells open, that supports the idea that the attempt failed.
What to do about a silent gap
If you are fairly sure it is empty, you can close the gap in the next cold season. Doing it in summer is not wise, as an apparently quiet nest may still hold wasps.
Note the location, and look at it again the following spring. A queen that failed in one spot will not be back, but another one might try. If the gap is a known weak point, it is worth the effort to fix it.
An empty cavity can take weeks to look fully empty, since pieces of the nest may be visible at the entrance. These fragments do not mean it is live.
Remember to check again in June. Queens that failed early sometimes leave an opening that another queen uses later in the season, although new nests begun late in the year have less time to grow.
A nest that comes back to life
Occasionally, what looked like a dead nest turns out to be active after all. If wasps start coming and going again, keep clear and arrange help. Do not go closer to check. A nest that appears to have come back is nearly always one that was merely quiet.
Wasps can swarm and sting if threatened, and the nest could be further developed than you think.
Keep your distance while you decide. A nest that is quiet may still defend itself strongly if you move too close.
Arranging help
Whether the nest is active or you are simply unsure, you are welcome to ask. A treatment for one nest costs a fixed £120 per nest, with an additional nest on the same property at £60 extra and no call-out charge. You will be visited by a fully insured and qualified technician, and the booking carries one visit guaranteed.
The number to call is 01622 410 019, or book through the form at /contact-us/. We work in Barnsole and nearby villages seven days a week, with same-day service and evening and weekend appointments. Tell us at booking if anyone at home is allergic to stings.
Describe what you saw, and when, as accurately as you can. It is surprising how helpful a few dates can be.
You can also use the online form to send a photograph of the gap, which often makes the position clear without a long description.
