Why Are Wasps Flying Into Your Horsley Cross Home? Common Causes and Solutions

Big doors and hatches are the least tight parts of a building, and they often form the route by which wasps reach the inside.

Where large doors leave gaps

A garage door, even a well-fitted one, rarely seals perfectly. Along the top, where the door meets the lintel, along the sides and at the base there can be gaps. Roller shutters and sliding doors have tracks and housings that offer shelter. Loft hatches sit in the ceiling and often have a gap around the edge.

These openings are attractive to a queen looking for a sheltered site, and they are the means by which wasps move around a building.

Wooden garage doors and older timber frames are particularly prone to gaps, as the wood moves with the seasons. Metal up-and-over doors have hinges and springs that leave spaces on each side. Keep these in mind when you look.

Garages also tend to hold the things wasps like: cardboard boxes, old furniture, bags of compost and stacks of timber. Combine this with a warm, dry space and an open door, and the result is a very acceptable nesting site.

How to inspect without risk

Stand at the front of the garage and look along the top edge of the door and the corners. On a warm day, watch for wasps landing on the door frame or crawling into a gap. Look at the track housing and at any boxes above the door.

Look also for:

• A faint hum above the door.
• Wasps drifting from the roller housing.
• Grey paper-like fragments on the floor beneath the door.
• A line of wasps along the top of the frame.
• Wasps appearing in the room above the garage.

Do not open the door fully in order to look inside if you see any of these signs.

Binoculars from a few metres away give a good view of the top corners of the door frame. Check in the afternoon, when wasps are busiest, and on more than one day. A wasp that disappears into a gap near the top of the frame is a strong clue.

Be careful about leaving the interior door to the house open. A nest in the garage can send wasps straight into the kitchen or hallway, and the first you will know of it is a wasp on the worktop.

Why not to operate the door

Opening or closing a door in which a nest is built creates vibration and movement. That can alarm the colony and cause wasps to fly out. It is safer to leave the door as it is until the nest has been dealt with.

If you need to get out a car, ask someone to stand well back, and move quickly. Better, if you can, use the vehicle elsewhere for a few days.

Roller doors in particular are a risk, because the roll sits in a box above the opening, often unlit and warm. Nests built there can be reached by wasps from outside through the runners, and their traffic is often visible as a trickle at the edge of the box.

If you suspect a nest in the roof space above a garage, the same advice holds. Do not climb up, do not tap the ceiling and do not try to block gaps. Describe what you see and leave the rest to a technician.

Loft hatches

A loft hatch is another opening to check. Wasps may appear around the hatch frame in the ceiling, indicating a nest in the loft. Do not open the hatch to see. Put a towel along the gap and keep the landing door shut.

Be aware that a loft in summer is hot and enclosed, and a nest of thousands can respond quickly. Leave investigation to a professional.

If you store items in the loft, think about what you will do about getting them down. Plan to wait until the nest has been treated, even if that means a delay of a few days. Nothing in a loft is worth a swarm of stings.

On the day of the visit, keep children and pets inside and away from the front of the house. The technician will tell you when it is safe to use the door again.

Practical measures

Keep the interior door to the house closed. Park the car outside if you can. Keep bins away from the door. Remove clutter near the entrance so that a technician has clear access.

Once the nest has been treated, fit a brush seal along the bottom of the door and a rubber seal along the top and sides.

Tell the technician if the garage is used as a workshop, a utility room or a home gym, as the people using it may be affected and may need to be told to stay away.

Do not worry about the state of the garage. The technician will deal with the nest wherever it is, and will not mind clutter.

Booking help in Horsley Cross

Wasp Nest Removal Essex charges £90 per nest, with one visit guaranteed, and £35 for an extra nest at the same property. It deals with homes and businesses, is fully insured and runs every day of the week, with same-day service available.

In Horsley Cross, ring 01245 327274 or send the booking form on the contact page. Mention the door or hatch involved and any wasp allergy in the household so that the booking can be prioritised.

If the garage has an up-and-over door that is stuck partly open, mention it as well, since it affects the way the wasps move and how the visit can be carried out.

Once the nest has been treated, think about repairs. A clean, sealed door is much less appealing to a queen the following spring.
