Nothing ruins a summer afternoon faster than the sound of wasps buzzing overhead. You step into your loft to fetch something, and within seconds you hear that unmistakable hum coming from a dark corner. Maybe you’ve spotted wasps slipping in and out through a gap in the roof tiles, or perhaps you’ve found a nest forming in your garage. Whatever the case, the presence of wasps around your home is more than just annoying – it can be genuinely frightening, especially if you have children, pets, or anyone with allergies in the house.
That’s why so many people turn to wasp foggers. These smoke bombs or fumigators fill a room with a fine insecticidal fog that spreads into every corner. Unlike sprays, you don’t need to chase individual wasps around with a can – you set off the fogger, leave the space, and let it do the work. The right fogger doesn’t just kill the wasps you see but also clears out hidden nests and stops infestations before they take hold.
But the challenge is knowing which product will actually work for you. Some foggers are better suited for large lofts, others for small sheds or outbuildings. Some are designed for all-round insect control, while others focus specifically on wasps. To help you make the right choice, I’ve reviewed a range of the best wasp foggers available now, focusing on how they perform, what benefits they bring, and which situations they’re most suited to.

What makes a wasp fogger effective?
Before diving into the reviews, it helps to understand what you should expect from a high-quality fogger.
Fast action matters most because wasps become aggressive when disturbed, and you need a product that can knock them out quickly. Wide coverage is another key factor since wasps love to hide in roof beams, loft insulation, and awkward spaces you’d struggle to reach with sprays. Consistent results are also important, because no one wants to waste time on multiple treatments.
Safety plays a big part too. These products are intended for enclosed spaces where people do not remain during treatment, so following instructions carefully is vital. Used properly, a fogger can give you a clean, wasp-free environment and a huge sense of relief.
Pest O One® Smoke Bomb Professional Strength Fogger
The Pest O One® Professional Strength Smoke Bomb is a strong choice if you want more than just wasp control. This two-pack fumigator targets not only wasps but also fleas, moths, cluster flies, spiders, and even poultry red mite.
The appeal is its professional-grade strength. When ignited, it releases a dense smoke that seeps into cracks, beams, and roof voids. This gives you the reassurance that you’re not only tackling the wasps you see but also reaching the ones hiding out of sight.
Because it comes in a pack of two, you can cover a larger space or save one for later in the season. If you live in an older house where multiple insect problems crop up together, this product is a great all-rounder. It feels like something a pest control expert would use, only packaged for homeowners to handle safely.
CritterKill Cluster Fly and Wasp Killer Smoke Bomb Fogger
If you need something to handle a wide area, the CritterKill 5g Smoke Bomb Fogger is designed for the job. Each unit covers up to 640 cubic metres, making it perfect for large lofts, barns, or high-ceilinged garages.
What stands out here is how well it works in hard-to-reach places. Wasps often build nests in awkward corners, and this fogger spreads smoke into those spots with ease. The four-pack offers flexibility too: you can treat multiple spaces at once or keep some in reserve for future infestations.
This option is particularly useful for rural properties where wasps and cluster flies return year after year. It gives you reliable coverage and the confidence that you’re dealing with nests hidden far out of reach.
Deadfast Garage and Loft Wasp Fumigator
The Deadfast Garage and Loft Wasp Fumigator is a practical, straightforward option for the two spaces wasps love most. Lofts and garages are warm, dry, and usually undisturbed, making them ideal nesting grounds.
The fumigator is simple to use. You light it, set it down, and let the smoke do its work. Within minutes, it spreads and clears the space. It’s not overcomplicated and doesn’t demand lots of preparation, which makes it a good choice if you want something quick.
Sold as a twin pack, it’s handy if you want to cover both a loft and a garage or keep a spare for the future. Since wasps often return to the same nesting spots each season, that second bomb is likely to come in useful.
Insectokil Smoke Bombs
The Insectokil Smoke Bombs come as a four-pack of mini foggers that can handle both flying and crawling insects. They’re not limited to wasps, which makes them a flexible choice if you’ve also got issues with cluster flies or spiders.
Because they’re smaller, you can target specific areas more precisely. That’s useful if you don’t want to fog an entire loft but just need to treat one section. You can also spread them across different areas of the house, tackling more than one problem at the same time.
The four-pack gives you good value and plenty of room for follow-up treatments. For homes where wasps keep coming back, having multiple units on hand makes managing the problem far less stressful.
Smoke Bomb Midi Fogger Fumigator Shredder
The Smoke Bomb Midi Fogger Fumigator is larger and heavier than the mini versions, at 15.5g each. This size makes a real difference when you’re dealing with a bigger infestation.
The thick smoke it produces spreads quickly and widely, making it highly effective in larger lofts, barns, or commercial spaces. If you’ve struggled with smaller foggers not finishing the job, the added power here gives you more confidence that one treatment will be enough.
Sold in packs of two, it provides a strong balance between coverage and convenience. You can double up for a particularly stubborn infestation or keep the second for later in the year.
Insecto Mini Smoke Bomb
The Insecto Mini Smoke Bomb is the smallest option at 3.5g, but it fills an important role. Sometimes you don’t need a large, powerful fumigator – you just want something to deal with a shed, a small room, or a single outbuilding.
Its compact size makes it perfect for targeting early infestations. If you spot wasps beginning to take hold in a smaller space, setting one of these off can stop the problem before it grows into a full nest. It’s also a useful option for people who want to save larger foggers for bigger jobs while keeping something smaller on hand for quick fixes.
Which fogger is right for you?
The right choice depends on both the size of the space and the scale of the infestation. If you’ve got a large loft or barn to clear, the CritterKill 4 Pack or the Midi Fogger Fumigator will give you the reach and power you need. If you want a product that handles a wider range of insects, the Pest O One® or the Insectokil Smoke Bombs are ideal. For quick, simple use in a loft or garage, the Deadfast Twin Pack is a safe bet. And if you’re only dealing with a small area or an early problem, the Insecto Mini makes perfect sense.
Final thoughts
Wasps bring anxiety and discomfort into your home, but with the right fogger you can take control. Each product reviewed here has a clear strength, whether it’s sheer power, wide coverage, or the flexibility to deal with more than just wasps.
The key is to match the fogger to your needs. Don’t use a heavy-duty bomb for a small shed, and don’t expect a mini fogger to handle a large loft buzzing with activity. By choosing carefully, you’ll save time, avoid frustration, and get the results you need.
Always remember to follow the instructions closely, leave the area while the fogger is active, and ventilate thoroughly before going back inside. Used properly, these products can bring peace of mind, letting you enjoy your home and garden without the constant worry of wasps.
