When you’re dealing with bed bugs, the first instinct is often to look for the quickest and cheapest solution. That’s why bed bug bombs—also known as foggers—catch people’s attention. They’re easy to buy, simple to use, and the promise of filling a room with insect-killing mist sounds like an instant fix. But before you rush out and buy one, the question you probably want answered is: how much is a bed bug bomb, and is it worth the price?
The cost isn’t just about the money you hand over at the shop. It’s also about what you get in return—whether it actually clears the problem or ends up costing you more down the line. Let’s break it all down, so you know what you’re paying for and what to expect.
What exactly is a bed bug bomb and why do people buy them?
A bed bug bomb is a small canister filled with insecticide. When you activate it, it releases a fog or mist that spreads across the room, settling on surfaces and killing insects on contact. The idea is simple: press the button, leave the room, and let the chemical do the work.
People buy them because they’re widely available, inexpensive compared to professional treatments, and marketed as a quick fix. If you’ve just spotted bed bugs in your bedroom, it feels tempting to grab a bomb and blast them out.
But here’s the catch: bed bugs don’t live out in the open. They hide in seams, cracks, and tight spaces. The fog from a bomb doesn’t penetrate those hiding spots very well, so while it might kill the bugs you see crawling on the surface, the rest of the colony often survives. That means cost isn’t just about the price tag—it’s about how effective it actually is.
How much do bed bug bombs cost on average?
The average price of a bed bug bomb is usually between £10 and £30 per canister, depending on the brand and size. Most are sold individually, but you can also find packs of two, three, or more. The coverage of each canister varies, with some designed for small rooms and others for larger spaces.
Several factors influence the price:
- Brand name: Well-known pest control brands charge more than lesser-known alternatives.
- Size of the canister: Larger canisters that release more fog and cover more space cost extra.
- Ingredients: Some bombs contain stronger active ingredients or additional chemicals like insect growth regulators (IGRs), which affect how effective they are.
- Special features: A few products are marketed as “extended kill” or “residual action,” and those tend to be on the higher end of the price range.
On the surface, it seems affordable. But remember, the cost depends on how many rooms you need to treat and how many times you’ll need to repeat the process.
What’s the difference between budget, mid-range, and premium bed bug bombs?
To really understand value, it helps to compare different categories of bed bug bombs.
Budget options
Budget bed bug bombs usually cost around £10–£15 each. They’re the most basic products, often smaller in size and covering just one small to medium room. They contain common insecticides such as pyrethrins or pyrethroids, which can kill bed bugs on contact but don’t always affect eggs or bugs hidden away in cracks.
If you’re only dealing with a suspected light problem in a small room, you might be tempted by the low price. But if the infestation is established, you’ll almost certainly need more than one, which means the cost quickly adds up.
Mid-range options
Mid-range bombs usually fall between £15–£25 each. These are typically larger canisters or products from well-known brands. They may claim to cover bigger areas or offer a longer residual effect, meaning the chemical continues working for a short time after application.
They’re popular because they feel like a balance between cost and effectiveness, but again, the main issue is that fog rarely reaches where bed bugs actually hide.
Premium or specialist options
Premium bed bug bombs can cost £25–£30 or more per canister. These might include additional chemicals such as insect growth regulators, which stop young bugs from maturing, or be marketed as more powerful formulas.
Some come in multi-packs aimed at whole-house treatments. While the features sound appealing, it’s worth asking whether the extra money is justified if the method itself has limitations.
What hidden costs should you think about?
When calculating the cost of bed bug bombs, it’s important to think about more than the sticker price. There are hidden costs and risks that might make them more expensive in the long run.
- Multiple canisters: Most people need more than one bomb, especially if they live in a house with several bedrooms or large spaces.
- Repeat treatments: Because bombs don’t always kill all the bugs, you may need to repeat the process several times. That’s more cost and more inconvenience.
- Wasted money: If the bombs don’t work, you’ve spent money without solving the problem, and you’ll still need another solution.
- Damage or residue: Some bombs leave chemical residue on surfaces, which you may need to clean. That’s more time and effort.
- Health risks: If used incorrectly, the chemicals can affect pets, children, or even adults. Misuse might mean paying extra for medical help or professional cleaning.
When you factor in these costs, the cheap initial price may not seem so cheap anymore.
Are bed bug bombs really effective?
The honest answer is: not very. Bombs are designed to release chemicals into the air and onto exposed surfaces. But bed bugs are experts at hiding in places the fog doesn’t reach—inside mattresses, behind skirting boards, in tiny cracks in furniture, or under carpets.
You might kill a few bugs wandering out in the open, but the majority often survive. Worse, there’s evidence that foggers can actually scatter bed bugs, pushing them deeper into walls and further across the home. That can make the infestation harder to control.
So while the cost seems low at first, the limited effectiveness means you may end up spending more overall as you try different products or eventually call in professionals.
What alternatives should you consider instead of bombs?
If you’re thinking about cost, it’s worth comparing bed bug bombs with other treatments. Some alternatives may cost more up front but save you money and stress in the long run.
Sprays
Bed bug sprays cost between £10 and £20 per bottle, depending on size and brand. Unlike bombs, you can apply sprays directly to seams, cracks, and hiding spots. This targeted approach makes them more effective, though it still requires thoroughness and persistence.
Powders (like diatomaceous earth)
Natural powders such as diatomaceous earth cost £10–£15 for a tub, and they work by dehydrating bed bugs when they crawl over treated areas. They don’t kill instantly, but they’re long-lasting and safe if used correctly. The cost is low, and the effectiveness is often higher than bombs when applied carefully.
Heat treatments
Heat is one of the most effective ways to kill bed bugs. You can use steam cleaners at home, which cost more initially but provide reliable results. Professional heat treatments are expensive—often hundreds of pounds—but they’re one of the few guaranteed methods to wipe out an infestation completely.
Professional extermination
Hiring professionals usually costs £200–£500 or more, depending on the size of the property. It’s a big investment, but when compared with spending money on multiple products that don’t work, it can actually be the cheaper option in the long term.
How do you choose a bed bug product wisely?
If you still want to try a bomb, or any other product, the key is to choose wisely. Look closely at the label and consider:
- Is it specifically designed for bed bugs? Some bombs are general insect killers, which may not target bed bugs effectively.
- What’s the coverage area? Make sure the canister matches the size of the room you want to treat.
- What chemicals does it use? Look for ingredients proven to affect bed bugs, and check for insect growth regulators if available.
- Are there safety warnings? Always follow instructions carefully to avoid health risks.
It’s also smart to read reviews, but remember that experiences vary. What worked for one person might not work for another, especially if the level of infestation is different.
Is a bed bug bomb really the best value option?
When you weigh it all up, bed bug bombs might seem cheap, but they often aren’t the best value. They can give you a false sense of security, making you think you’ve solved the problem when the bugs are still hiding and breeding. That means more money spent on repeat attempts and potentially bigger infestations later.
Sprays, powders, and heat treatments may require more effort, but they tend to deliver better results. And if the problem is serious, calling professionals straight away could save you hundreds in the long run by stopping the infestation before it spreads further.
Final thoughts: price matters, but results matter more
So, how much is a bed bug bomb? On average, you’ll spend £10–£30 per canister, with bigger or more advanced products costing more. That might seem like a bargain compared to other options. But the real question isn’t just “how much does it cost?”—it’s “how much does it solve the problem?”
If a bomb only kills a handful of bugs and leaves the rest untouched, the true cost is higher than the price tag. You’ll waste money, time, and energy, and you’ll still be dealing with the infestation.
If you’re dealing with bed bugs, think about long-term value. Prevention, careful inspections, targeted treatments, and sometimes professional help are better investments than relying on a fogger alone. Price is important, but effectiveness is what really counts when it comes to bed bugs.
