How to Tell If You Have an Active Wasp Nest on Your Birch Property

Guttering, downpipes, garage doors and their frames have hollows that hold a nest quite happily, and the clues are often seen first at head height.

Parts of the house that no one inspects

Guttering and downpipes are the sort of thing you notice when they leak and ignore the rest of the time. Garage doors are opened and closed without a thought for the frames and housings around them. Yet both have hollow spaces, from the back of a gutter run to the box above an up-and-over door, and both are sheltered from rain.

A nest in one of these places is easy to miss until it becomes large, because it sits on or close to a structure you pass daily. The wasps themselves are often the first clue, noticed as a small, constant stream near the door.

Gutters and downpipes

Wasps can use the gap between the back of a gutter and the fascia, the space where a downpipe bracket is fixed, or the open top of a pipe. Plastic and cast iron alike will serve. A sagging gutter with a gap above it is a particular invitation.

Watch for wasps landing on the gutter and walking into the gap, or hovering around a pipe joint. You may see staining or grey flakes on the wall beneath. Do not poke into a pipe or hose water into it. Water will force the wasps out and expose them to the air, which is likely to enrage them.

• Check the gutter line from the ground with binoculars.
• Notice where wasps seem to vanish into the run.
• Avoid clearing leaves from the gutter until you are sure it is clear.

Mild signs are worth noting too. A gutter that suddenly looks stained, a faint papery smell near a downpipe or a pile of dead wasps at the base of a wall can all mean there is a colony in the structure. Take a few photos over a couple of days. If the stains or pile grow, that is a sign of activity.

Garage doors and their housings

Up-and-over doors have a large box mechanism above, with springs, brackets and gaps. Roller doors have a roll housing. Side-hinged doors have frames with hollow sections. Any of these can hold a nest. A garage with a damaged seal or a gap at the top of the frame gives wasps easy access.

Standing outside the door for a minute, listen for a hum and look at the top corners and the seal. Do not operate the door if you think a nest is present, as the movement shakes the whole structure. Use another entrance if the garage has one, or leave the door alone until treatment.

Roof-edge work is not for amateurs. If you suspect a nest in a gutter at height, resist the temptation to get out the ladder and have a look. The combination of height, awkward reach and a nest within arm’s length is a recipe for accidents. Leave it to a fully insured technician who has the right equipment and experience of working at height.

Meanwhile, keep the ground below the gutter clear. A wasp disturbed by the vibration of a wind-blown branch or an animal can fall or fly down, and people sitting beneath are the most exposed.

Cars, bikes and stored items

A garage full of stored items offers wasps more places to build, from the folds of a tarpaulin to the space behind shelves. If you park a car in the garage, think about the risk of getting in and out of the vehicle near the nest. Wasps disturbed by the opening of a door may fly around the car.

Leave the car where it is if you can, or park elsewhere for a few days. If you must retrieve something, do not rush in. Wait until you have checked from outside, and consider whether it can wait for the technician to confirm the situation.

Many garages are also used as workshops or utility spaces. If you do DIY or laundry in yours, think about moving the activity indoors for a few days. Noise and vibration from power tools, washing machines and compressors can all disturb a nest, and the doorway is likely to be the wasps’ route in and out.

If you have a connecting door between the garage and the house, keep it closed. Wasps can enter the house through the same gaps used by pipes and cables.

Other fixtures at head height

Look also at outdoor light fittings, hanging baskets, wall-mounted bird boxes, satellite dishes and the tops of fence posts. Each of these can hold a small nest, and they are at a height where you are likely to bump into them. Do not shake or remove any item that has wasps near it.

If a hanging basket is the issue, do not take it down. Wasps will pour out of it. Leave it, keep away and describe it when you book. Remember that some of these items will need a ladder to reach, which makes them best left to someone insured and prepared for the work.

Finally, after treatment, ask the technician about the entrances. Once you have confirmed there is no activity, gaps in gutters, brackets and door frames can be sealed or repaired, which reduces the chance of a queen settling there next spring. Do this only when you are certain the nest is no longer in use.
