Do Wasps Return to the Same Nest Every Year? A Guide for Hoddesdon Gardens
A wasp colony follows a fixed calendar from spring founding to autumn collapse, and understanding that calendar explains why old nests are never reoccupied.
A season in the life of one colony
It helps to see the whole year laid out, because the answer to whether wasps return to the same nest sits at the end of it. In early April, depending on the weather and how mild the spring has been, a queen that has survived the winter picks a site and builds a small starter nest. She lays eggs, feeds the first grubs herself, and the first workers emerge to take over the building and foraging. From then on the colony grows quickly. More workers mean more cells, more cells mean more workers, and the nest swells outward. By August it is at its peak and may hold as many as 2,000 wasps. That is the stage at which most people notice wasps at picnic tables, drinks and bins, and also when most calls for help come in.
What happens as autumn arrives
Towards the end of the summer the colony changes direction. The queen stops laying eggs that become workers, and instead the nest produces new queens and males. These leave to mate. The old queen and the workers have done their job, and as the weather cools they die off. By the time the first hard frosts arrive the nest is quiet. This is why wasps seem especially irritable in late summer. Workers that no longer have grubs to feed are looking for sugar for themselves, so they turn up at sweet drinks, fruit and sticky bins. The behaviour is a sign of a colony in decline, not growth. In and around Hoddesdon, as anywhere, the nests you see in September are the ones nearing the end. Treating a late nest is still sensible if it is close to doors, children’s play areas or a path you use daily, because the wasps remain defensive until they die off.
What the new queens do
The young queens that leave the nest in autumn are the only members of the colony that carry on. Each one finds a sheltered hiding place and stays there through the cold months. In spring she emerges alone, and she does not go back to the nest she came from. She looks for a new site, and the cycle starts over. That is the key point for anyone with an old nest on their property. The abandoned structure has no further role. A queen would have to build a new nest, because the old one is damaged by weather, is full of old cells, and is of no use to her.
Reading the signs in each month
A rough calendar helps you spot problems:
- April and May: single wasps investigating fences, sheds and eaves, and a small nest with a few workers.
- June and July: increasing traffic to one entrance, and a faint buzzing from a wall or roof void.
- August: peak numbers, wasps around food and drink, and larger nests that may be visible.
- September and October: wasps become more erratic and then fall in number.
- Winter: an empty nest, with no flying insects.
This is only a guide, since weather moves everything by a few weeks either way. If you see a steady stream of wasps going in and out of one hole at any point in the year, treat it as a live nest until proven otherwise.
What to do with a nest found in autumn or winter
If the weather has turned properly cold and nothing is moving, the nest is dead. You can leave it, or you can remove it with care. If it is in an accessible place such as a shed rafter or a hedge, wear gloves and eye protection, and bag it up. If it is inside a wall, a chimney or beneath roof tiles, it is best left in place. Taking things apart to reach a finished nest can cause more trouble than the nest itself. Once it is empty, the wasps cannot hurt you, and a new queen will not use it. Be careful in the early part of autumn, when the nest might still hold wasps. If you are not sure whether there is activity, watch the entrance for a few minutes on a mild day from a distance, rather than going close. Sometimes a householder finds a busy nest in September and assumes that something went wrong earlier in the year, or that the colony is going to carry on into winter. Neither is the case. Nests simply go unnoticed until the numbers are high, particularly if they are in a roof void or behind a hedge, and the colony will still collapse as the weather cools. It is also worth knowing that wasps seen in October and November are not usually new arrivals. They are stragglers, young queens that have not yet found a place to rest, or workers close to the end of their lives. A slow, sluggish wasp on a cold windowsill is no reason to think a nest is nearby.
Late-season nests and what treatment involves
A live nest in September is worth dealing with if it affects how you use your home or garden. The fixed price is £70 per nest, and £30 for an additional nest on the same property. No call-out charge applies, and you are told the price over the phone before anyone visits. Where a nest needs special access equipment to reach, the price might be more, and you will be told before any work starts. Nothing is done without your agreement. The technicians are fully insured and qualified, and they work seven days a week, with same-day service offered and evening and weekend appointments available. Domestic and commercial customers are both covered. To arrange a visit, call 07852 111 437, or use the online booking form or the contact page. If anyone at the property is allergic to stings, say so when you book so that the booking can be prioritised.
