Wasps Around Your Guttering and Fascias? How to Find the Nest in Shelley

A nest at the gutter this summer says something about the building, and a short seasonal routine of checking and mending can keep next year’s founding wasp from choosing the same gap.

Why the same building gets visited again

Wasps do not reuse an old nest, and the colony dies off in autumn. But the next spring, a new founding wasp goes searching for somewhere sheltered, and a gap that suited one wasp will suit another. If the opening is still there, the same corner of the roofline may be chosen again, sometimes in consecutive years.

This is why dealing with a nest is only half the job. The other half is making the gap unavailable. That does not require a big project. A short routine through the year, with a few small repairs, is usually enough to make the roofline a poor choice.

There is a further reason to bother. Small gaps tend to become larger gaps, because water, frost and wood-chewing insects work at them. A repair costing little in November can avoid a more serious fix, such as a replacement board, a few years later.

Winter: the time for repairs

The cold months are the best time to mend the roofline. There are no active wasps, the nests of the previous season are empty and the weather, though cold, offers dry days when work can go ahead. Choose a calm day and ask a tradesperson with the right access equipment to inspect the fascias, soffits, bargeboards and gutters.

Ask for the following to be checked and repaired where needed.

• Cracked or split boards and open corner joints.
• Soft or rotted timber at board ends.
• Missing or damaged soffit panels and vent covers.
• Gaps where pipes and cables pass through the wall.
• Loose trims on porches, bays and extensions.

An old nest left in a cavity does no harm, but if one is exposed during repairs, ask the technician or tradesperson how best to remove it.

You can also do a lot yourself from the ground. Check the paint on the fascias for peeling, look for sagging gutters and note any place where a bracket is missing. Make a short list with photos and show it to the tradesperson, who can then give you an accurate quote.

If a gutter needs replacing or realigning, winter is a good time to do that too. A sagging gutter holds water against the board, which accelerates decay, and the gap between the gutter and the fascia is another place where wasps can enter.

Early spring: watch for scouts

From late April, depending on the weather, founding wasps come out and look for nest sites. They are large wasps, often seen flying slowly along walls and fences, and landing to inspect small holes. You may see one crawl into a gap, back out and fly away. That is a scouting visit, not a nest.

If you see a wasp repeatedly entering the same gap, however, that is the start of a nest. Take note and consider acting then. A young nest is small and far easier to deal with than a mature one.

Do not try to catch or kill a scouting wasp yourself. It achieves little and risks a sting. If you have already found the gap she is using, close it once you are sure that no wasps are inside. If you are not sure, ask for advice before sealing anything.

Summer: a weekly look

Once a week between May and September, stand back and watch the roofline for a minute or two in the sun. It costs nothing and takes no time. You are looking for any change: a new stream of wasps, a hum from the eaves, wasps indoors. If something is there, you will notice it when it is still small.

Do this from the ground. Never climb to look closer. Keep the habit going even if the previous summer was quiet, since a nest can appear in any year.

It is useful to keep your weekly notes brief, with the date, time and what you saw. A quick note on your phone is plenty. If the notes show an increase from one week to the next, that is your cue to ring.

Neighbours matter too. Wasps do not respect boundaries, and a nest on the roofline next door can send workers to your garden. A friendly word about the weekly watch is better than a dispute over a nest in August.

Autumn: tidy up

When the colony has died and the weather cools, check the roofline again and make notes for winter repairs. Clear food waste from the garden, and lift fallen fruit, which attracts late-season wasps. Look at the place where this year’s nest was, if there was one, and check that repairs are in the diary.

If you did not have a nest, take a quick look anyway. A gap that you can see now is a gap a wasp can see next spring.

Think too about any outbuildings, garages, sheds and summerhouses, which are checked less often than the house and can have equally good gaps.

If you rent the property, make a record of what you have done and report any damage to the landlord or agent. Who pays for repairs depends on the tenancy agreement.

If a nest does appear

A routine reduces the odds, it cannot eliminate them. If a nest forms, treat it promptly. The technician for Shelley and the surrounding villages will treat the nest at its source. The charge is £90 per nest, fixed, with one visit guaranteed, and a further nest on the same property adds £35 to the bill. We are open seven days a week, offer same-day service, cover homes and commercial premises and are fully insured.

Keep this page in mind each spring. Many nests are found late simply because nobody was looking early, and a weekly glance from the garden costs nothing.
