Last August a reader emailed us a photo of her patio table. Four adults, a bowl of strawberries, and what she described as “a small army” of wasps working the jam jar. Her youngest had been stung on the lip the week before, and she had stopped eating outside altogether. The thing she asked us was not how to kill a nest. It was: “Why didn’t anyone tell me what to do in March?”

That question is the reason this guide exists, and why we are publishing it in November when there is not a wasp in sight. By the time wasps are a nuisance, the decisions that decided how bad your summer would be were made months earlier. Most advice online is written in August, in a panic. This is written in the quiet, so you can plan.

We already have a guide on what actually kills a wasp nest. This one is the other half of the story: the traps, lures and decoys that aim to stop a nest getting going, or keep wasps away from the places you sit. We will be straight with you about something else too. The evidence for some of these products is thin, and several listings promise more than they can prove. You should know that before spending a penny.

How we chose these wasp products

We have spent years advising UK homeowners on garden and household pest problems, and wasp questions arrive in a predictable wave every summer. For this guide we did the following:

• Read every manufacturer listing line by line and noted what each product claims, what it leaves out (active ingredients, pack sizes, usage instructions) and where the wording contradicts itself.
• Checked the biology against BPCA material on the wasp life cycle, so that timing advice is based on what queens and workers actually do rather than on marketing.
• Picked different approaches on purpose: a ready-to-hang trap, a lure bait for traps you already own, two decoy nest products, and an enclosed-space fumigator. No single method suits every garden.
• Excluded anything that harms people, pets or wildlife in obvious ways. Where a product contains a biocide, we say so and point you to the label.
• Checked prices on our own product pages in November 2026. Amazon prices move, so treat the figures as a guide.

One honest caveat up front. Every product reviewed here currently has zero customer reviews on our site, so effectiveness claims are the manufacturers’ own. We have not run controlled trials, and neither has anyone selling these. Where we are guessing, we say so.

Quick comparison table

What wasps are doing right now (and why it matters for your purchase)

Understanding the year a wasp colony lives through changes which product you buy and, more importantly, when you put it out. Here is the short version, drawing on the BPCA’s explanation of the wasp life cycle.

Winter: the queens are asleep

Mated queens spend the winter in dark, dry, sheltered spots: loft insulation, garden sheds, behind cladding, in stacked pots, even in the folds of old curtains in an unused garage. Most of them survive. Every old nest you see in your attic this winter is already empty and will not be reused, because wasps do not return to an old nest. The colony died off in autumn.

Spring: one queen, one job

When the weather warms, each queen wakes and goes looking for a nest site. This is the moment that matters. The BPCA notes that a nest counts as established once the queen has five to seven workers, and that many founding nests fail anyway because queens fight over sites, or because a cold, wet spring knocks them back. In other words, a lot of what you do in spring is nudging a process that is already fragile.

Summer: the explosion

Once workers take over, the nest grows quickly. A German or common wasp nest can hold around 5,000 wasps at its summer peak. Workers are sterile females and nearly all die before they are three weeks old, so the colony is constantly replacing itself. By late summer the workers lose their job of feeding grubs, which is why they turn up at your picnic hunting sugar. A single nest can produce 1,000 to 2,000 new queens in a season, which is how a few nests nearby turn into the following year’s problem.

Autumn: the nest dies, the queens leave

New queens leave to hibernate and the old nest collapses. This is why wasps seem to go from nowhere to everywhere in August and September, then vanish almost overnight.

What this means for you: traps hung in early spring target the individual queens who are scouting. Traps hung in late summer target workers that are already at peak numbers and mostly there for sugar. The first approach tries to prevent nests; the second just reduces annoyance. Both can be worth doing, but neither will clear a large established nest, and you should not expect them to.

Five wasp traps and deterrents reviewed

1. Entopest 2 x Wasp Trap Kit – best ready-to-use trap (£26.99)

This is a two-trap kit with an included hanging system and a pre-supplied attractant. You hang the traps in the garden, wasps are lured in, and they cannot easily get back out. The listing pitches them for gardens, fruit trees, dining areas and poolsides, and says disposal is quick and clean.

Pros:

• Everything needed to start is in the box, with two traps so you can cover two spots
• Hanging design keeps the trap off the ground and out of the way
• Passive, with no spraying and no need to find the nest

Cons:

• The title says “nest killer”, but the description only describes a trap. It will not destroy a nest.
• The listing gives no trap capacity, bait lifespan or active ingredient, and no placement distances
• Our product page shows “3 pieces” while the description says two traps, so check what arrives
• The most expensive option here

Honest caveat: any wasp trap can catch things you did not intend, including bees, hoverflies and other beneficial insects. Check traps often and place them where you do not want honeybees working. Also, an attractant draws wasps towards the trap, so do not hang it above the table you are sitting at. Place it several metres off, ideally downwind.

Best for: gardens with fruit trees or an outdoor dining spot that gets hit every August. Not ideal for: anyone expecting this to solve an existing nest in the loft.

2. Entopest Wasp Lure Liquid 250ml – best refill for traps you already own (£9.99)

A liquid attractant designed to be poured into an existing hanging wasp pot. The listing says it is compatible with Entopest traps and “most other hanging wasp pots”, and that a bottle should cover multiple refills through the peak season.

Pros:

• Cheap way to keep a trap you already own working
• Useful across a long season, when a single fill goes stale

Cons:

• The title and spec say 250ml, but the description mentions a 100ml bottle. Pack size is unclear.
• No dosing, refill frequency or ingredient information on the listing
• Useless on its own, as it needs a trap to go in

Honest caveat: this is a biocide. The only safety text on the listing is a general reminder to read the label, so do read it, keep it locked away from children and pets, and never decant it into a drinks bottle. That last one is how most household poisoning incidents with garden products happen.

Best for: people with an old hanging wasp trap that has gone dry. Not ideal for: first-time buyers with no trap at all.

3. GWHOLE Wasp Nest Decoy – cheapest experiment (£8.99)

Paper decoys shaped like wasp nests, hung under eaves, pergolas, sheds or branches. The theory is that a queen scouting for a site sees what looks like an occupied nest and goes elsewhere, because wasps are territorial. The listing says each pack holds four decoys, around 8.7″ by 11″ each, and claims they drive wasps beyond a 200 ft radius.

Pros:

• Non-toxic, no refills, no maintenance
• Very low cost, so little to lose if you only want to try it

Cons:

• The 200 ft claim has no test data behind it
• Paper, with no weather rating on the listing, so expect it to need replacing after a wet British winter
• The listing says to remove any active nests first, so this is prevention, not a cure
• Our page lists a unit count of 1 but the description says four decoys

Honest caveat: the research on decoy nests is mixed at best. Some gardeners swear by them and some see wasps nesting right next to the fake. What decoys do have going for them is timing: they only make sense if they are up before queens start searching in spring, and if they are positioned like a real nest (high, sheltered, a couple of metres from any other decoy, since the idea is that rival nests keep apart).

Best for: a no-chemical trial under eaves and outbuildings. Not ideal for: anyone with an active nest, or anyone who needs a guarantee.

4. Plai 4-Pack Wasp Decoy Nests – better-built decoys (£13.99)

Four decoy nests, described as weather resistant and chemical-free, aimed at gardens, balconies, patios and sheds. They are marketed as discouraging new colonies from forming nearby. The listing does not claim they remove existing nests.

Pros:

• Weather-resistant build, which matters for something you hang outside all spring and summer
• Four pieces give you more coverage than a single decoy
• No toxins, so fine around children and pets

Cons:

• No placement instructions and no explanation of how many you need per area
• No independent evidence for the deterrent claim
• The listing calls it both “biological pest control” and a “pest control device”, which is confusing

Honest caveat: same evidence problem as every decoy. Think of it as one layer in a plan, and combine it with sealing gaps and tidying food sources rather than relying on it alone.

Best for: people who want decoys that survive a full season outside. Not ideal for: anyone who wants proof before buying.

5. Deadfast Garage and Loft Wasp Fumigator (twin pack) – for empty outbuildings only (£9.00)

An insecticidal smoke candle for enclosed spaces. The idea is that you treat an empty garage, shed or loft in late autumn or winter, when hibernating queens may be tucked into cracks and crevices, so that fewer of them wake up in spring. The listing says it reaches cracks and crevices and eliminates flying and crawling insects.

Pros:

• Reaches into gaps you cannot spray
• Low cost per treatment

Cons:

• The listing gives no active ingredient, burn time, coverage area or instructions beyond “read the label”
• The title says “wasp” but the target species is just “insects”, and the description says indoor use while the title says garage and loft
• It is a hazardous product and our listing contains no guidance on ventilation or protective equipment

Honest caveat: this is the product to treat with the most caution. The listing itself warns against inhalation, ingestion and skin contact. Never use fumigators in an attached loft that shares airflow with living areas, never near stored food or pet cages, and never with a pilot light, boiler or any ignition source nearby. If your loft is above bedrooms, skip this and call a professional. Read the label completely, and it is the label, not our summary, that governs safe use.

Best for: detached garages and sheds that are empty and can be closed up and aired afterwards. Not ideal for: any space people or animals use, or any loft connected to your home.

If you already have a nest

Traps and decoys do nothing for a thriving colony. If wasps are streaming into a hole in the wall or roof, you need a nest treatment, not a deterrent. Our guide on what actually kills a wasp nest covers the options, including Rentokil PSW97 Wasp Destroy Foam (£6.69) for nests you can safely reach.

Step-by-step: a year-round wasp prevention plan

1. November to February: find and seal. Walk the outside of your home on a dry day. Look for gaps in fascias, soffits, air bricks, roof tile gaps and cracked render. Seal anything larger than a pencil width. Check sheds and garages for access points. Do not seal a hole if you can see wasps active in it, because trapped wasps will chew through into your house.
2. December to February: clear hibernation spots. Tidy rubbish in sheds and garages, shake out stored fabrics, and move stacked pots. Queens like quiet clutter.
3. Late winter: decide your approach. If you want decoys, buy them now. Hang them before the first warm spell, typically March, in the places a queen would look: under eaves, inside porches, in the corners of sheds and pergolas.
4. March to April: hang spring traps. Hang one or two traps, well away from where you sit. Bait them sparingly. At this stage you are trying to catch individual queens, so a handful of catches is a success.
5. May to June: check for early nests. Look in sheds, under decking and in roof spaces on warm days for a golf-ball-sized grey nest. Early nests are far easier and safer to deal with than August ones.
6. July to September: reduce temptation. Cover food and drinks outdoors, wipe sugary spills, keep bins lidded, and pick up windfall fruit daily. Move traps to the edge of the garden to pull wasps away from your seating.
7. Empty and re-bait traps carefully. Wear gloves, wash your hands afterwards, and dispose of contents in a sealed bag in your household waste. Do not tip them down a drain or onto the compost.
8. October to November: take everything down. Clean traps with hot soapy water, store them dry, and bin any weathered decoys.

A word on homemade traps

The classic sugar-and-water bottle trap does catch wasps, and many people use them. The downside is that it also catches plenty of other insects. If you prefer homemade, keep the entrance small, hang it away from flowering plants, and empty it frequently. It will not do better than a ready-made trap, but it costs nothing.

Health and safety: what UK homeowners need to know

Wasp stings are usually painful rather than dangerous, but they can be serious. Here is what the NHS advises:

• For an ordinary sting: scrape the sting out sideways with a fingernail or the edge of a bank card. The NHS says not to use tweezers. Wash with soap and water, apply a cold pack or cold wet cloth for at least 20 minutes if swollen, and take paracetamol or ibuprofen for pain. Antihistamines or hydrocortisone cream can ease itching.
• Get urgent medical advice (an urgent GP appointment or NHS 111) if you are stung in the mouth, throat or near the eyes, if you are stung several times, or if you have previously had a serious allergic reaction to a sting.
• Call 999 for swollen lips, mouth, throat or tongue, difficulty breathing or swallowing, wheezing, very fast breathing, blue, grey or pale skin, sudden confusion or drowsiness, fainting, or a child who is limp or unresponsive.

Product safety basics:

• Wear gloves when handling lure liquid or emptying traps.
• Keep every biocide in its original container, out of reach of children and pets.
• Always read the product label before use. It is a legal requirement that you use biocides as directed.
• Never use a fumigator in a space where people or pets will be, and ventilate fully before re-entering.
• Wear long sleeves, closed shoes and a hat if you are working near a nest, and never do it in the daytime when wasps are at their most active.
• Do not stand on a ladder to deal with a nest. A fall is a far likelier injury than a sting.

When to call a professional

Deterrents are for prevention. You should call a professional if:

• You can see wasps flying in and out of a hole in your roof, wall or soffit
• The nest is bigger than a football, or is higher than you can safely reach from the ground
• Anyone in the household has had a serious allergic reaction to a sting
• The nest is inside a wall cavity or loft space
• You are not sure whether you have wasps, hornets or bees. Bees are protected and often not a pest at all.

Look for a member of the British Pest Control Association (BPCA), whose members are trained and checked. Your local council may also offer a treatment service for a fee. For more on getting help, see our pest control service page.

Frequently asked questions

Do wasp traps actually work?

They catch wasps, but catching wasps and solving a wasp problem are different things. A trap can reduce the number of workers hunting around your seating, and a spring trap may catch queens before they nest. It will not remove an established nest, and it will not stop wasps from a neighbour’s nest from visiting. We would treat a trap as a way to reduce annoyance rather than a cure.

Do fake wasp nests work?

The evidence is mixed. The theory is sound in that wasps are territorial and often avoid building close to another nest, but independent testing is scarce and none of the products reviewed here comes with proof. They are cheap and harmless, so they make a reasonable low-cost experiment if you hang them before spring.

When should I put out wasp traps in the UK?

Early spring, typically March to April depending on where you live, to target queens. Then again from late summer if workers are a nuisance. Traps put out in July and August will mostly catch workers.

Will a wasp trap attract more wasps to my garden?

It can, if it is hung near where you sit. The bait is designed to attract wasps, so place traps several metres from seating, play areas and doors, and ideally downwind.

Are wasp traps safe for pets and children?

The trap body is plastic, but the bait inside is a biocide. Hang traps out of reach, keep the lure liquid locked away, and read the label. Wasps trapped inside can still sting if the trap is opened, so empty it carefully with gloves.

Do wasps reuse old nests?

No. Wasp nests die off each autumn and are not reused the following year. A new queen starts a fresh nest. You can safely remove an empty old nest in winter, but it is worth sealing the entry point so a new queen does not move in.

Can I get rid of a wasp nest myself?

Small, accessible nests can be treated with a proper nest-killing product, used exactly as the label says and at dusk. Anything high, large or inside a cavity should be left to a professional. See our wasp nest guide for detail.

Seasonal activity: the UK wasp calendar

• Winter (December to February): Queens are hibernating. Seal gaps, clear sheds, and treat empty outbuildings if you choose to.
• Early spring (March to April): Queens emerge and search for nest sites. This is the time for decoys and spring traps.
• Late spring (May to June): Queens lay eggs and the first workers appear. Nests are still small and easy to deal with.
• Summer (July to August): The colony explodes. Expect wasps around food and drinks. Cover everything.
• Early autumn (September to October): Peak nuisance. New queens leave to hibernate and the old nest begins to die. Wasps become more desperate for sugar.
• Late autumn (November): The colony is gone. Clear traps and plan for spring.
