Do Wasps Return to the Same Nest Every Year? A Guide for Blaby Gardens
Dense planting gives queens plenty of places to build out of sight, and autumn pruning is the safest moment to see which ones were used and why.
Nests among the leaves and why dense planting suits queens
A hedge or an overgrown shrub can hold a wasp nest that nobody notices until a pruning job goes wrong. The nest is usually inside, hung from a branch or tucked into a fork, hidden by leaf cover.
As in other settings, the nest is used for one season only. When the colony dies in autumn, the paper structure is left in the branches and will not be reoccupied. In a Blaby garden with a long hedge or mature trees, the more useful questions are where a queen might choose to build and how to see them in time.
A queen wants shelter from rain and wind and a position that is not disturbed. Thick evergreens and overgrown shrubs provide exactly that. Hollows in old trunks, ivy-covered walls and the base of tall hedges do the same job.
Pruning keeps the structure open and makes nests easier to see. It also reduces dark, still corners. The aim is not a bare garden but one where you can see what is going on.
Pruning safely
The main danger is clipping a hedge in summer and cutting into a nest. Wasps will pour out and defend themselves, and you may be holding a noisy hedge trimmer at the time.
- Check the hedge for wasp traffic before starting any work between April and September.
- Look for a steady flow of wasps entering one point in the foliage.
- If you see one, stop, walk away calmly and keep others clear.
- Postpone the job until the nest has been treated or the autumn comes.
- Never push a trimmer into dense growth blindly.
Cutting back in late autumn or winter is the safest time, because the colony is gone.
Dealing with old nests in branches
Dead nests in trees and hedges can be left to weather away. They are light and fragile and often collapse within a year. If one is in the way, wait until it is cold and lifeless, then bag it and bin it.
For nests in tall trees or at awkward heights, leave them be. Climbing is a poor trade for a harmless empty nest. If you want it taken down, ask the technician at booking whether that is possible.
From late April, depending on weather, queens begin choosing sites. Take a quick walk past your hedges and trees once a week and watch for wasps hovering and entering the same point.
Include boundary fences, climbing plants on walls and any hollow stumps. These are the sort of places where nests develop unnoticed until the colony peaks in August, with 2,000 to 10,000 wasps or more.
Fruit trees and sheltered boughs and climbers on walls and fences
Orchard and fruit trees deserve a special mention. Wasps like fallen fruit in late summer, so a tree can attract workers even if the nest is elsewhere. Pick up windfalls regularly and keep a lid on compost.
Older fruit trees often have hollows and cracks that give queens a dry spot. A hollow in a branch fork with wasps entering and leaving is a sign of a nest. Do not try to smoke or poke it out. Keep clear and make a note of the location.
Autumn is the time to inspect branches when the leaves fall, because nests that were hidden all summer become visible against the sky.
Ivy and other thick climbers give shelter to everything from birds to insects. A queen may choose a cavity behind the stems, where the wall meets the fence or where a trellis leaves a gap.
If you have climbers on the house, keep them cut back from eaves, gutters and vents. This is good for the building as well, and it makes any early nest easier to spot. Pruning at the right time of year, when no wasps are active, makes the work much safer.
A thin, open climber near a wall is a different thing from a dense mat, and the less dense it is, the fewer hiding places you have to check.
A small autumn walk
After the first cold snap, take a slow walk around the garden with a torch and look into the denser parts of the planting from outside. Note any grey papery shapes. Do this with a friend if possible and avoid reaching into growth you cannot see.
It takes a quarter of an hour and tells you a great deal about what happened over the summer.
Piles of clippings, brash and old pruning can form warm hollows at the base of a hedge. Clear them away after trimming, or stack them neatly away from walls and fences so that no cavity forms.
Do the same with old plant pots and spare timber. Fewer hollows means fewer choices for a queen looking for a home.
Look for leaves that have been stripped or chewed at the edges of a plant, small piles of fibre near fences and a regular wasp flight path through the foliage. None of these proves a nest, but together they point to one. Stay on the path and use your eyes, not your hands.
