Wasp nest removal for homes

What a wasp nest treatment involves

In most cases it takes one visit. The technician finds the nest, puts on protective clothing, and applies insecticidal dust or spray into the entrance. The application takes 10 to 15 minutes. Most wasps are dead within two to four hours, and the whole colony within 24 to 48 hours.

Removing the nest is optional. An empty nest is harmless and will not be reused, because wasp nests are annual. Ask whether removal is included in the price, or whether it costs extra.

Before the visit, keep windows shut, keep children and pets away from the area, and make sure the technician can reach the nest. You may still see a few wasps around the nest for a day or two, so keep clear until they stop.

When wasps are a problem

Queens emerge from March to May and start a nest. The colony grows through June and July. It is August and September when wasps are most aggressive, as larval food runs out and the workers go looking for sweet food elsewhere, including at picnics and bins. The first hard frosts kill the workers in October. A mature nest can hold 5,000 to 10,000 wasps by August.

Spring weather decides how busy a year is. 2025 was a boom year after the warmest, sunniest spring on record, and one firm treated 317 nests by late August against a usual 40 to 60. Not sure what you have? Read how to identify wasps.

What a professional does that you should not

Some nests are not safe to treat yourself. A professional works from a ladder or platform, in a cavity, in the roof space or near eaves, and with a suit and the right product for the site. They also know which insect it is, so you are not treating a bee colony by mistake.

Call a professional for any nest bigger than a tennis ball, any nest in a wall cavity, loft, roof or eaves, anything near a door or window, a nest that needs a ladder, and anyone with a sting allergy. If you are not sure, call. Read the DIY guide for the few cases where you can act yourself.

Bees, hornets and the law

Wasps are not protected, and nothing in the law prohibits killing them or destroying a nest. Honey bees have no blanket legal protection either, but pest controllers refer swarms to a beekeeper through the British Beekeepers Association (BBKA). Bumblebees should be left alone.

The yellow-legged hornet, often called the Asian hornet, is different. Do not treat it yourself. Please report it through the Asian Hornet Watch app or the online form. We found no statutory duty to report one, so this is an official request, not a legal requirement. Government now uses the name yellow-legged hornet, so you may see both names.

Choosing a wasp controller

No licence is needed to treat wasps. BPCA assesses member companies against BS EN 16636 and requires £2m public liability cover. NPTA is a trade association with training, insurance and a code of practice, and its Accredited tier is audited. BASIS PROMPT records an individual's qualifications and annual training, and RSPH Level 2 is the baseline technician award. None of these is a licence, and a credential shows training, not skill on the day.

Ask how many nests the price covers, whether removal is included, and whether a return visit is free if the nest is re-colonised. Many firms guarantee the treated nest.

Does the council treat wasps?

Most councils treat wasps, usually for a fixed fee, but some do not. Check yours before you book a private firm. Some councils limit what they treat: Solihull, for example, cannot treat above the gutter of a three-storey house. See council pest control for fees by council. For private prices, see wasp nest removal costs. In a busy season firms can be stretched, so book as soon as you find a nest.

A wasp nest in a rented home

Pests count under the housing hazard of domestic hygiene, which includes exposure to pests. A nest in the roof is usually the landlord's job to fix, so tell them in writing and keep a copy. A nest in the garden or a shed you control is more likely to be yours. If the nest is in the roof space, do not go up to look at it yourself.

Wasps in the house

A single wasp indoors is usually a stray. Many wasps coming in and out, especially with all the windows shut, point to a nest in the building. Watch where they fly in and out, from a distance, and look for an entrance in the wall, eaves, loft or chimney.

Keep windows shut, keep children and pets away, and do not block the hole or spray inside, which can send wasps into the room. Call a professional, who will find the nest and treat it in one visit. If anyone has swelling of the mouth or throat, or trouble breathing after a sting, call 999.

A wasp nest in the wall

A nest in a wall cavity shows as a stream of wasps going into a gap, often by an air brick, a crack in the mortar or a hole under the eaves. You may hear scratching or buzzing inside.

Do not try to treat or block it. Powder puffed into a cavity needs the right product and skill, and a blocked hole can send the wasps into the room. Call a professional. The treatment still takes one visit, and the colony dies within 24 to 48 hours. Removing the nest is optional.

A wasp nest in the loft

A nest in the loft is out of sight, so the first sign is often wasps in the house or on the ceiling. Do not go into the loft to look: there may be thousands of wasps, and you could fall through the joists.

Call a professional, who will treat it from the entrance or inside. A nest found in winter is usually empty, because the workers die in October and wasps do not reuse it, but check with a professional before you disturb it. Tell your landlord if you rent.

Wasps in the roof or eaves

Wasps go in under roof tiles and in the eaves because the gap is dry, warm and quiet. You will see a steady flow of wasps to one spot, usually at the edge of the roof.

This is not a job for a householder. It needs a ladder or tower and the nest is hard to see. Work from a ladder near a nest is a job for a professional. Call one, and keep people and pets away from the area.

A wasp nest in the lawn

Wasps nest in old burrows in the ground, so you may see them flying in and out of a small hole in the lawn or a bank. A lawn nest is easy to disturb with a mower, which brings out an angry swarm.

Keep people and pets off the area, and mark the hole from a distance. Do not block the hole. A small, open nest can be treated at dusk with a purpose-made powder, but a professional is the safe choice, and the council may treat it for a fixed fee.

A wasp nest in the shed

Sheds, garages and outhouses are quiet and warm, so wasps build nests under the roof, in the corners and in stored items. Keep the door shut and look from a distance for the entrance and the paper nest, which is grey-brown and layered.

An accessible nest may be small enough to treat yourself with a powder or aerosol made for wasps, at dusk from 4 to 5 metres away. If the nest is bigger than a tennis ball, in a roof space, or near the door you must use, call a professional.
