Wasp Nests Under Roof Tiles – A Common Problem for Cilcewydd Homes
Wasps need very little room to get into a roof, and understanding the gaps they use helps you spot a problem early and explain it clearly when you call.
A pencil-width gap is enough
It surprises many people how small an entrance can be. A queen looking for a site in spring does not need a hole you could put a finger in. A crack the width of a pencil, a missing speck of mortar or a lifted edge of felt is all she requires. Once inside, the nest can grow into whatever space is behind the tiles or the boards.
That is why a roof that looks perfectly sound from the garden can still house a colony. The entrance is small, the nest is out of sight and the first sign is often a handful of wasps coming and going at one spot.
Wasps start building in early April, depending on the weather and how mild the spring is, and the colony grows through the summer to a peak in August.
Roofs also move with the weather. Timber expands and contracts, mortar weathers, and felt can lift in the wind. A gap that was not there last year can appear without anyone doing anything wrong.
A queen has all spring to inspect a house, and she tries a great many cracks before settling. That is why wasps are often seen crawling around the roof edge in April and May without yet having a nest to show for it.
The usual ways in
Roofs have many joints, and wasps find the ones that offer shelter. Typical routes include:
- Gaps where roof tiles overlap or where a tile has slipped slightly.
- Joints between a fascia board and the wall.
- Spaces at the corners of soffit boards.
- Holes around vents, pipes or cables passing through the roof edge.
- Gaps beside chimneys, bargeboards and the ends of the roof.
None of these points to a badly kept house. Every roof has joints, and wasps look for any that suit them.
Chimneys deserve a special mention. The junction between brick and tile is a classic place for small gaps, and a warm flue wall suits a colony. If the wasps are working around a chimney, describe the stack and which side of the roof it sits on.
Dormer windows, porches and extensions add more joints to the roofline. If your house has any, say so on the phone.
What this means for your home near Welshpool
Cilcewydd is in Powys, near Welshpool, and the business covers homes in the area. The wasps in the village behave as wasps do anywhere, and the same signs apply.
If you have noticed wasps at a particular corner of your roof, you do not need to know which kind of gap they are using. Your description of where they land and disappear is enough for the technician to work from.
Take care not to confuse wasps with other insects. If the insects you see are furry and round, they may be bees, and you should speak to a local beekeeper or the relevant bee organisation. The business treats wasps.
The business works across the area around Welshpool, and a visit can be arranged for the same day where possible. If you are not certain whether your address is covered, ask when you call.
Leave the gaps alone for now
Because the entrances are so small, there is a temptation to go round the house with a tube of sealant. That is a poor idea while there is an active nest. A sealed gap traps the colony and sends workers looking for another route, which can lead indoors.
Equally, avoid poking at the gap with a stick or running water into it. Both annoy the wasps without dealing with the nest.
Once the technician has treated the nest and the wasps have gone, a builder or roofer can close the gap for good.
There is a safety point as well as a practical one. Anyone working near the roof edge with a tube of filler is working at height, often on an unstable ladder, with wasps nearby. It is not worth the risk.
Fixed price, whatever the roof
A nest in the eaves is treated for £80 flat, the same as a nest anywhere else. There is no call-out charge and no added cost for location or time of day. A further nest on the property is priced at £40 flat. One visit is guaranteed.
The technician is qualified and fully insured, and the work is safe and effective. The business is open seven days a week, offers same-day service and works with homes and commercial premises.
Many people ask whether they should wait to see if the wasps move on. They do not. A colony stays put until the autumn, and in the meantime it grows. There is no saving to be made by waiting, and the fixed price means no penalty for calling early.
If you are unsure whether the insects are wasps, say so. The business will ask a few simple questions and tell you whether it sounds like a job for them.
Booking and what follows
Ring 07916 322 280, or fill in the online booking form. Tell the business where on the roof you have seen the wasps entering, and say if anyone is allergic to stings so the booking can be prioritised. Evening and weekend appointments are available.
After treatment, the traffic should fade. Dead wasps may drop into the gutter or onto the path, and you can sweep them into a sealed bag.
Ask whether the empty nest can be taken down. In spring, a quick look at the roof edge may catch a new queen early.
Keep your phone handy during the visit. The technician may want to ask where you saw the wasps land, and a quick answer from you saves time. Pets should stay indoors with the door closed.
