When Is Wasp Season in Halstead?

A deck or pergola is built for long summer days and sunny lunches, which is exactly when wasps are busiest, so a careful check of the structure pays off.

Outdoor rooms and the wasp calendar

Decking, patios, pergolas, summer houses and garden bars have become an extension of the home. People eat, entertain and relax out there from spring to autumn. That makes them the part of the property where wasps and people are most likely to meet, and it is worth understanding how the season affects them.

Not every structure is a nest site, but several features can be. The space under raised decking, the hollow posts of a pergola and the gaps in a timber summer house all provide shelter, and holes in the ground beside a patio are used too.

Before the season: inspect and tidy

March and early April are a good time to look at your outdoor spaces. With few wasps around, you can check safely under the deck, along the beams and behind the cushions store. Clear leaves and debris from beneath raised boards, and note any gaps between planks and the house wall.

• Look at the underside of any raised deck from the edge, using a torch.
• Check the tops of pergola posts and any hollow sections.
• Look at the join between a lean-to roof and the house.
• Inspect the ground beside paving for holes.

Repair loose boards and fill obvious gaps if you can do so from a safe position.

Late April to June: building starts

Nest-building gets going from late April, depending on the weather, and from then on you should pay attention when using the space. If you see wasps repeatedly flying to a point on the deck, the house wall or the roof of a summer house, they may have a nest there. Note the position and watch it from a distance on a warm afternoon.

The presence of a few wasps on a warm day is nothing unusual. What matters is a pattern of repeated visits to one place. A sudden increase in the number going to the same spot over a fortnight shows that a colony is establishing.

A hot tub, a garden bar or a firepit on the patio brings warmth and smells, both of which wasps notice. Keep lids on drinks and sweet snacks, and move seating away from the nearest wall or hedge when you see wasps are about.

July and August: the table under the pergola

By midsummer the colony is expanding quickly, and in August it peaks, with a nest able to hold from 2,000 to 10,000 or more wasps. Food, drinks and barbecues out on the deck attract plenty of visitors. Keep dishes covered, use jugs with lids and clear plates swiftly.

Take care with the barbecue. Smoke does not make a nest safe, and hot coals or sprays near a wall that hides a nest could make matters much worse. If you notice wasps near the cooking area, move the cooking elsewhere, rather than trying to chase them away.

Fairy lights, parasols and cushions are often moved into place in the afternoon, and a parasol pole knocked against a hollow post can disturb a nest. Handle furniture gently if you know wasps are about.

Take a minute at the start of each season to look at the furniture you store in a shed or under cover over winter. Cushions, covers and parasols can all shelter a wasp, so shake them out before use.

Under the deck: the hidden risk

Raised decking with a gap beneath is a sheltered, dark space. Pets and children can squeeze through, and a nest underneath is hard to spot. If you hear a hum from under the boards, or see wasps disappearing between planks, close off the access and keep everyone away.

Do not push anything into the gap, pour liquids or use smoke. If a nest has been found, avoid walking heavily on the deck above it, since vibration passes through the boards.

Once the nest is treated, ask the technician at booking whether the empty nest can be taken down, and consider fitting mesh to the edges next winter.

Think about lighting too. Lanterns and string lights on a pergola draw insects, and wasps may come along with them, so position them where they will not hang over the dining table.

Getting back to summer days outdoors

A nest near the deck can spoil a whole summer, but it is a straightforward problem to fix. Describe the position to the booking team as accurately as you can, including how high, which side, and what the structure is made of. Tell them how people reach the spot, in case a side gate or a locked garden is involved.

After treatment, wait for the technician's advice before going back to the area, and then check the structure again each spring. Little habits such as keeping bins away from the deck and wiping tables quickly will make the next summer more comfortable.

It also helps to think about the layout for next year. If your seating sits right under the eaves, consider moving it a few metres into the garden for the summer. A table in the open is easier to watch and a nest on the house is less likely to affect it.
