Wasps Around Your Guttering and Fascias? How to Find the Nest in Carlton
Wasps at the gutter may be thirsty, hungry or building, and what you do next depends on which, so it pays to watch their behaviour before deciding.
Three reasons wasps visit the roof edge
Wasps at the gutter fall into three rough groups. Some are drinking from damp spots and small leaks. Some are scraping wood fibre from weathered timber to make paper for their nest. And some are coming home to a nest in a gap nearby. Only the last of these means you have a colony on the property, though the second suggests there is a nest somewhere not far away.
Telling them apart is a matter of watching how they behave. In Carlton, as anywhere, a calm quarter of an hour at a window or across the garden is the best tool you have.
Weather plays a part. In dry spells wasps look harder for water, and in wet ones they spend more time sheltering. A hot, dry week often brings wasps to the damp parts of a house, so the sudden appearance of wasps at a gutter after a heatwave is not always alarming.
Try not to react to a single sighting. A wasp on a gutter in July is about as unusual as a sparrow on a fence. What matters is repetition, the same spot, many wasps and the same pattern day after day.
Drinkers
Wasps that land on a damp patch, bend down and sip are drinkers. They often gather at a leaking joint, a stained board or a spot where condensation collects. They tend to arrive, drink for a few seconds, and fly off in a straight line.
If this is what you see, the wasps probably have a nest elsewhere, but not necessarily in your house. A dripping joint is worth repairing once the season is over, because it offers water and also damages the board. It is not an emergency, and a single drinking wasp is not a reason to book.
It is worth looking at the whole run of guttering and the downpipe. A stain or a green patch on the wall marks the spot where water has been escaping for some time. Fixing it is a plumbing or building matter, and it is best done once the wasp season has passed, with the right equipment and a safe way of working at height.
Wood scrapers
Wasps that move slowly along a weathered board, with their jaws working, are collecting wood fibre. They chew it to a pulp and carry it off to build nest paper. You may see pale grey marks or shallow scratches on old timber, a fence post or a shed where this has been going on.
A scraping wasp is a worker from a nest, and that nest could be some distance away. It could be in your eaves or in a neighbour’s garden. If you see many wasps doing this on the same board, assume a nest is close and start looking harder.
Painted and treated timber is less attractive than bare, weathered wood. If you see scraping on an old shed, a gate or a fence post, it is a sign wasps are in the area, and the nest may be in your hedge, your neighbour’s loft or somewhere else entirely.
Because the scraper is a worker, there is a nest behind her. Follow the direction she flies away when she has a load, if you can do so from a safe distance. Wasps usually take a fairly direct line home, and that line can tell you where to look next.
Home-comers
Wasps that fly to the roof edge, vanish into a gap and reappear a few moments later are the clearest sign. A steady stream at the same gap, building through the day, is a nest.
- Watch from a distance, not from underneath.
- Look for the same wasps entering with food or fibre.
- Note whether the traffic rises on warm afternoons and drops at dusk.
- Photograph the roof edge from the ground if you can.
Do not climb up, tap the board or block the gap. A colony peaks in August, when a nest can hold as many as 2,000 wasps, and a nest that is disturbed can swarm.
If your observations give a mixed picture, give it another day. Wasps that visit are generally gone by evening. A nest produces activity from first light until dusk, and that daily rhythm is the strongest hint you will get.
When you have collected your impressions, decide how confident you feel. Fairly sure is enough to call. If you are sure there is no stream into a hole, it is reasonable to wait. The business can help with a borderline case if you describe it on the phone.
Deciding and booking
If you are fairly sure there is a nest, book. If you are not, keep watching for a day or two or ring and describe what you see. The price is a fixed £70 per nest and £30 for an additional nest on the same property, confirmed on the phone before the technician visits. Phone 07852 111 437 or use the contact page or booking form. Evening and weekend appointments are available, and the technician is alerted by text and email. If anyone at home is allergic to stings, say so when you book.
Commercial properties such as shops and workshops can book on the same terms, and a quiet time can be arranged for the visit.
For a rented flat or house, tell the landlord or agent about any nest, and check the tenancy agreement about repairs. If you share an access path or a roof with a neighbour, let them know.
