Wasp Control for Dunsville Restaurants, Pubs and Commercial Premises

Small businesses often discover a wasp nest in a store, shed or loading area they rarely visit, and the staff safety questions are different from a busy dining room.

The nest nobody was looking for

Plenty of commercial wasp problems start out of sight. A storeroom that is only opened twice a week, a lean-to at the back of the yard, a roller shutter that is rarely lifted: these are exactly the quiet spots a queen wasp may choose in spring. By the time somebody goes in to fetch stock in July, there is a colony living in the space.

Nests are begun in early April, depending on how the weather behaves, and they expand through the summer until they peak in August. At that point a single nest can hold as many as 2,000 wasps. A cupboard-sized nest in a ceiling void may go unnoticed for weeks and then become obvious within days, as the numbers climb.

For a business in Dunsville, near Hatfield, the pattern is no different from anywhere else. The point is to recognise the first signs before somebody walks into the cloud of wasps.

What makes a store room attractive is mostly that it is undisturbed. Dry, dim and warm, with small gaps around pipes, vents or the edge of the roof, it mimics the sheltered places wasps look for in the wild. Cardboard boxes and stacked crates add more hiding places, and the quiet of a room that no one uses most of the day lets the colony settle without any disturbance.

If the business also has a cellar, a garage or a lean-to, add those to the list of places to check, and ask whoever opens up first in the morning to keep an eye out.

Warning signs inside and around a building

Staff who use the storeroom are the best early-warning system, so it is worth asking them what they have noticed. The following are worth reporting straight away:

• wasps in a window or skylight of a room that is usually quiet;
• a handful of wasps hanging around a gap in a ceiling tile, a vent or a crack in a wall;
• a dry, rustling sound from a roof space or wall;
• small bits of chewed paper-like material on a shelf or the floor;
• wasps flying in a regular line to and from one point in the yard.

If you see any of these, close the door to the room, tell the rest of the team and stop anyone going in until it has been checked. It is much safer to lose half a day of access to a store than to have a staff member stung repeatedly while lifting a box from a shelf.

It also helps to look at the outside of the building on a bright afternoon. Wasps leaving a nest tend to travel in a steady flow, and watching a wall for five minutes from the opposite side of the yard can show you a pattern that you would never spot from inside. Take a note of the position in relation to a window, a drainpipe or a door, so that you can describe it clearly on the phone.

A short staff briefing that actually helps

Not every employee will know what to do around a nest, so a few lines on a noticeboard or in the morning huddle can make a difference. Keep the message plain:

• do not go near the area, and do not try to look at the nest;
• do not swat, spray or bang on walls, because that provokes a defence;
• move away slowly if a wasp lands on you, and do not run;
• report any sting to the manager so it can be looked after.

For a sting, wash the area, take out the sting if you can see it, and use a cold pack. If someone develops swelling of the face, lips or throat, wheeziness or difficulty breathing, dizziness or a widespread rash, call 999 immediately. Staff who know they are allergic should talk to their GP and tell their manager.

What the technician will want to know

The Wasp Exterminator treats wasp nests for domestic and commercial customers, with fully insured and qualified technicians. A nest costs £70 per nest, fixed, with £25 for an extra one on the same property and no call-out charge. If the nest is somewhere awkward and special access equipment is required, the price might be higher, and you are told that on the phone before anyone is sent. Nothing starts without your agreement.

To make the call quick, work out beforehand where the wasps are entering, whether the spot is inside or outside, and whether it is high up. Say whether the area is staffed, who will let the technician in and whether there is stock or equipment that cannot be moved. Mentioning an alarm or key arrangement saves time on the day.

Expect the technician to ask whether anyone has been stung, whether anyone on site has a known allergy, and whether pets or children use the yard. These are sensible questions, and honest answers make the visit safer for everyone.

Getting it booked and the area back in use

The service is open seven days a week, with same-day visits available, so a nest found at a quiet moment can be sorted without much lost trade. You can ring 07798 792 774, or send the online booking form or contact page, and the technician in your area receives an SMS and an email as soon as it is submitted.

After the visit, keep the area closed for as long as the technician advises. If you would like the empty nest removed from a ceiling or wall space, ask at the time of booking whether that is possible. Once the area is back in use, check the room regularly through the summer, because a fresh queen may look at the same sheltered spot again next spring. Sealing gaps that can be seen from the inside is worth considering, and a handyman can usually do it.

Leased units and shared buildings

If your unit is part of a larger building, the nest may be in a wall, roof or void that belongs to somebody else. Rather than guess, look at your lease, or ask the owner or managing agent who is responsible for pest problems. Whatever the answer, do not leave a nest in place while the discussion goes on, because the colony only grows. Tell the technician about the situation so that the right person can authorise the work.
