Take an insecticide can and direct the nozzle around the perimeter of the roof. Apply a thin layer to the entire surface of your roof, concentrating on the areas near the wasp nests. If wasps come looking for a place to nest, they will avoid your roof and seek out another location.
When wasps build nests in or around your home, they create havoc. They will aggressively defend their territory if you approach a nest or attempt to disturb them.
Wasps are attracted to roof vents because they are covered and thus provide protection.
If wasps are not dealt with immediately after they begin nesting, an infestation becomes more likely. Eliminating wasps from roof vents requires vigilance to prevent their return.

How to Get Rid of Wasp Nest in Roof
Spray an insecticide into the vent to eliminate any wasps that may be present. To avoid inhalation, wear a breathing mask and follow all instructions on the package.
At dusk, when wasps are more likely to be dormant within the nest, spray.
For several days, cover the vents with plastic bags to prevent additional wasps from entering the system.
Inspect your attic for possible wasp entry points into the vents. Breaks in the insulation or small holes in the wood are frequently used entry points for wasps.
Any breaches must be sealed to prevent the entry of additional wasps. Protect yourself against stings by wearing long-sleeved shirts and long pants.
Consult a professional if wasp problems persist, as wasp stings can be dangerous, even more so if you are allergic to them.
The following are some products that you can use to treat a wasp infestation:
DeltaDust Multi-Use Pest Control Insecticide Dust: As the world’s first and only insecticide dust that is completely waterproof, this wasp-killing dust is effective in both wet and damp environments.
This 32-ounce bottle of Cutter Backyard Bug Control Spray Concentrate treats up to 5,000 square feet. Connect it to your garden hose and use it to spray the wasp nest from afar.
RESCUE! Yellowjacket Reusable Trap: If you prefer to purchase a wasp trap rather than make your own, this popular product is effective. It contains a non-toxic attractant and is therefore safe to use around pets and children.
Spectracide Wasp & Hornet Killer: This insecticide kills wasps, hornets, and yellow jackets using a 27-foot jet spray, including insects that return to the nest days later.

Safety is even more critical when dealing with wasps and bees than it is in general. When you are attacked and/or stung, you may experience a panic attack and act without thinking.
Wear protective clothing
To further reduce your risk of being stung, wear long-sleeved shirts, long pants, socks, gloves, shoes, a hat, and even a face covering and safety goggles. And this is true regardless of the season. There are no excuses for the heat outside.
Locate the Wasp Nest
If you noticed wasps entering through your soffit, they could be nesting in the eaves directly above the soffit or in the attic’s rafters.
Utilize the exterior entry point as a reference point for locating the nest. If wasps are present, the sound of wasps chewing wood during the day may direct you to the nest.
Approach the Nest Early in the Evening or Early in the Morning
It is critical to eliminate the nest while all of the wasps are ‘at home.’ While this may seem counter-intuitive, it is preferable to remove the nest while the wasps are dormant.
Spray the Nest with Water or Wasp Killer
If the nest is visible from the outside after removing the soffit, you may be able to spray the nest with water.
Ensure that the hose’s nozzle is set to the high-velocity setting. A pressure washer has the potential to cause damage to your roof.
Continue spraying the nest until it is completely soaked and destroyed by the water. Prepare an escape route in the event of an attack.
If you use a wasp killer, follow the manufacturer’s instructions.
Where are Wasp Nests usually Found?
Typically, nests are discovered and constructed in sheltered areas. These frequently include wall cavities, roof spaces, sheds, and gardens. You can locate a nest by observing the return flight path of wasps.
How NOT to get rid of a wasp nest
There is a wealth of information available online about the most effective ways to get rid of wasp nests without using professional products. This is not recommended and will almost certainly result in serious injury to you or whoever is removing the nest.
Using a hose pipe or a bucket of water
Water is another frequently used method for attempting to destroy a wasp nest. However, if your wasp nest is located indoors, using water may actually result in increased property damage.
Additionally, flooding the nest will not eliminate wasps; it will only increase their aggression toward you, resulting in painful stings.
Destruction of the nest
Using fire to exterminate wasp nests is both dangerous and ineffective.
Wasp nests are constructed of a thin chewed wood pulp substance, which is extremely flammable and thus extremely dangerous in and around your home.
Additionally, the fire will not eliminate the wasps and will only increase their aggression.
Utilization of a baton/physical force
Brave individuals may resort to using a baton-like tool, such as a baseball bat, or even physical force, in an attempt to destroy their wasp nest.
This is the most dangerous method of all because it requires you to be in close proximity to the nest, putting you at risk of being stung and harmed.
If the nest is in the loft, you could use a smoke bomb instead of removing any flying wasps from the area before treating the nest.
How to Remove a Wasp Nest
Now that you know how not to get rid of a wasp nest, we’ve put together some effective steps for safely and effectively removing one.
Before approaching the nest, ensure that you are wearing protective clothing, including gloves and a wasp veil.
If you are unable to access the nest entrance, we recommend using a wasp nest killing spray such as the Digrain Wasp Nest Destroyer.
You may prefer to treat the nest entrance with a powder formulation if you have access to it. Both Residex P and Ficam D are highly effective, but they require an applicator, such as a Pest Pistol Powder Duster or a Dustick Duster.
Make your way to the nest
Approach slowly and carefully at a time when the nest is least active. This is most likely at dusk or very early in the morning.
If you must approach the nest in the dark and use a torch, avoid shining it directly on the nest and make a plan for access and escape.
Apply your spray or powder
Once you are in a position to spray the nest, grab your preferred product and thoroughly spray the entire structure.
Puff the wasp killer powder directly into the nest and around the entrance if using one. This will ensure that any wasps returning to the nest following treatment bring the product with them.
Re-apply if necessary
Once the product has been applied to the nest, vacate the area and wait to determine if the treatment was successful.
How to Remove a Wasp Nest from the Roof
If you have a wasp nest in your roof or another difficult-to-reach location, you will need a different set of products.
The Dustick Duster is indispensable for treating wasp nests at height or in difficult-to-reach locations. Alternatively, a wasp smoke bomb can be used to reach nests located at a height or in an enclosed area.
How to get rid of a Wasp Nest in a Bush / Shrub
If you have a wasp nest in a bush, you will most likely need to spray the nest from a distance.
A spray, such as the Insecto Wasp Nest Destroyer, is a foam solution that kills wasps instantly from a distance. Alternatively, you could use Digrain Wasp Nest Destroyer, which has been shown to effectively destroy wasp nests.
How to get Rid of a Wasp Nest in a Loft
Eliminating wasp nests in lofts is difficult because they are typically located in inaccessible, difficult-to-reach areas.
As with a wasp nest in the roof, you will require a specialized set of products. If you are confident that you can safely spray the nest, we recommend the Digrain Wasp Nest Destroyer.
If the nest is inaccessible, you can use the Dustick Powder Duster, which enables you to spray insecticide directly onto the nest from a height due to the expandable pole solution.
Another method for eradicating wasp nests in lofts is to employ a Wasp Fumer. As long as there are no open areas in the loft, a wasp bomb will fumigate the entire structure and instantly kill wasps.
How to get rid of a Wasp Nest in an Air Brick
Due to the difficulty of safely applying product to wasp nests in air brick, a new set of challenges can arise.
We recommend using a wasp killing powder such as Ficam D and applying it from a distance through holes in the air brick using a Polminor Insect Powder Duster.
Applying wasp powder directly to the nest is far more effective than spraying from a distance.
How to Prevent Wasp Nests
As is always the case, prevention is preferable to cure, and this is especially true when it comes to wasp nests.
Prevent wasps from becoming a nuisance this Summer by following some of these simple yet effective tips.
Check for nests on a proactive basis
Check your home and garden for wasp nests during the Summer months. The sooner you identify a nest, the easier it will be to eradicate.
Examine common areas such as sheds, roofs, voids in roofs, lofts, and bushes.
Eliminate food sources
As the Summer months progress, we spend more time outside, frequently leaving sweet food out, instantly attracting wasps.
Ensure that food preparation areas are kept clean and that any leftovers are disposed of promptly. If wasps continue to feed successfully, they will continue to search for food in the same area.
Wasp proof areas of your home
Wasps can fit into the tiniest cracks, holes, and gaps, so sealing these areas significantly reduces the likelihood of wasps building nests.
If this is not done, nests may form in lofts, attics, roof voids, and other difficult-to-reach areas.
Kill visible wasps indoors
Wasp activity is known to be high during the Summer months, so it’s a good idea to keep a wasp killer spray on hand for dealing with wasps that find their way indoors.
Eliminating these wasps will help reduce the likelihood of a larger infestation forming.
Maintain and clean waste / garbage bins
Rubbish bins, both indoors and outdoors, are a major source of wasps attracted to your home. Empty these bins regularly, especially during the warmer months, to avoid a buildup of waste food.
If outdoor bins are attracting a lot of wasp activity, you may want to consider moving them further away from your property. The closer they are, the more likely they are to enter your home.
How are Wasps Introduced into a Home?
Wasps are drawn to the sweet aromas of flowers and plants, as well as to food sources such as pet food, crumbs, and spills. They will enter your home if it has an easily accessible entry point in search of a safe space to establish their nest.
Are there any Natural Wasp Repellents?
Yes. Wasps despise pungent herbs like spearmint, thyme, citronella, and eucalyptus, as well as essential oils like clove, lemongrass, geranium, and lemon. Additionally, you can use natural sprays, traps, or solutions to eliminate or deter wasps.
What Distinguishes Wasps from Bees?
While wasps and bees both belong to the Hymenoptera order of insects, bees can sting only once, whereas female wasps can sting multiple times.
Both are critical to our ecology and should be killed only if they pose a threat to your health.
