- Prevent first, repel with scents, trap foragers, use targeted sprays on small nests at night, and call a pro for large or hidden colonies.
- Keep patios clean, seal any gaps, and place traps a safe distance away from seating areas.
- Major nests near people = professional removal.
How can you get rid of wasps in Calgary without making things worse? It’s a question many homeowners ask when summer arrives and outdoor spaces become crowded with buzzing invaders. It is not a smart act to spray randomly. Instead, you are making wasps more aggressive, leaving the queen untouched, which means the colony bounces back.
The smartest way to get rid of wasps is to use prevention first, like keeping food covered and sealing gaps. Then use natural repellents, simple bait traps, and careful sprays for small nests. For big or hidden nests, call a professional.
Why Wasps Are a Problem (and When to Leave Them Alone)
Wasps can sting repeatedly and become aggressive in late summer, so nests near people need removal.
Wasps are common in Calgary during the warmer months. They usually start building nests in spring and expand rapidly through summer. By late July or August, colonies can contain hundreds of workers, and it is during this time that they become aggressive. A single wasp sting is painful, but multiple stings can be dangerous – especially for children, pets, or anyone with allergies.
Wasps build their nests in Calgary, typically in these spots:
- Under decks or eaves
- In sheds or garages
- Inside attics and wall voids
- Burrowed underground in lawns
However, not every nest requires action. If a small nest is far from human activity, it may be safe to leave it alone since most colonies naturally die off by fall. However, if a nest is located near doors, patios, or play areas, removal is the best choice.
What Are The Smart Preparations You Need Before Any Act
Before removing wasps, always protect yourself, choose the right time, and plan carefully.
Do not rush into wasp control without preparation, as it is risky. Wasps defend their nest aggressively, and multiple stings are no joke. For your complete protection, take these steps first:
- Wear protective clothing: Wear long sleeves, gloves, closed-toe shoes, and eye protection to reduce the risk of stings.
- Work at night or dusk: Wasps are less active, and most are inside the nest during these hours.
- Plan an escape route: Always know how to retreat safely in case wasps attack.
- Identify nest type:
- Aerial nests hang from trees, roofs, or eaves.
- Ground nests are often hidden in soil burrows or lawn holes.
- Hidden nests may be inside walls, attics, or hollow logs.
- Gather your tools: You may need a spray, a homemade trap, a flashlight with a red filter (which is less visible to wasps), or a sealable bag for disposal.
How Can You Get Rid of Wasps? Proven Methods
Use natural and DIY methods for small problems, and escalate to chemical or professional solutions for larger nests.
Natural & DIY Methods
These methods are safer and often enough for smaller wasp problems in Calgary.
- What Smells Do Wasps Hate?
Wasps have a strong sense of smell. Some scents confuse and repel them, making your space less attractive for nesting.
- Peppermint – It is one of the strongest natural repellents.
- Clove – It has a sharp-smelling substance that wasps dislike.
- Lemongrass – Its fresh scent works well outdoors.
- Eucalyptus – This tree adds protection around patios and gardens.
How to use: Mix 10–15 drops of oil with water in a spray bottle and mist around windows, eaves, and sitting areas. You can also plant mint or lemongrass in pots near outdoor spaces. Cotton balls soaked in essential oils placed near entrances also help.
These smells don’t kill wasps but act as a natural barrier, discouraging them from nesting near your home.
- Wasp Trap Bait Recipe
It’s a simple DIY trap that can catch wasps before they bother your family. This trap lures worker wasps searching for food. It won’t wipe out a whole nest, but it helps reduce activity around high-traffic areas.
Recipe:
- 1 cup fruit juice or sugar water
- 1 tablespoon vinegar (keeps bees away)
- 1 drop dish soap
Steps:
- Cut the top off a plastic bottle and flip it upside down into the base to make a funnel.
- Pour the bait inside.
- Place the trap a few metres away from patios, doors, or dining areas.
- Empty the bait and refill regularly.
- Soapy-Water Spray (Small nests only)
Use dish soap and water; it kills on contact. Use at night.
A mix of dish soap and water clogs the breathing holes of wasps, which eventually kills them quickly. Spray directly at night onto small nests or individual wasps. Do not forget to maintain a safe distance.
- Decoy / Fake Nests
Hang some decoy or fake nests early in spring to discourage new colonies.
Wasps are territorial. When you hang fake nests in spring, it will discourage new colonies from forming nearby. These are inexpensive, reusable, and innovative prevention tools.
- Physically Remove the Nests (Only for tiny, early nests)
You can bag, detach, seal, and bin – only when nests are golf-ball size.
For very small, early-stage nests (golf-ball size), you can bag and remove them. Place a thick bag over the nest at night, detach it carefully, seal it, and dispose of it. Do not try to remove large or active nests.
Chemical & Professional Methods (Use With Caution)
Sometimes DIY isn’t enough. For medium to large nests, chemical products or professional help may be required.
- Aerosol/jet sprays: Spray from a safe distance. Never stand directly under a nest. If the nest is knocked down, wasps can fall on you.
- Dust treatments: Puff dust at the entrances of the ground nest. Workers carry it inside to the queen. Works best at night.
- Hidden nests (walls/attics): If you see wasps flying but cannot find the nests, then it’s a professional job. Trapped wasps chew new exits, often into living spaces.
- Professional Pest Control: It is the safest choice for large nests, hidden colonies, or aggressive species, such as yellowjackets. Major Pest Control Calgary uses safe equipment, guarantees removal, and prevents re-infestation.
What Should You Do To Prevent Their Return After Removal
Wasps are resourceful. If your yard has food or shelter, they may return. Prevent this by:
- Remove old nests: When a nest is no longer active, remove it and dispose of it properly. Don’t leave “starter pieces” behind.
- Seal entry points: Fill cracks and gaps in siding, soffits, fence posts, under decks, and around pipes or cables.
- Control waste: Keep bin lids tight. Rinse sticky bottles and cans. Keep the area under the bins dry.
- Reduce sweets: Pick up fallen fruit, wipe drink spills, and keep outdoor drinks covered.
- Use plants and scents: Place mint, marigold, or lemongrass near doors to create a pleasant aroma. Refresh essential oil sprays weekly during peak season.
- Do a spring check: In April or May, look for tiny, thumb-size starter nests and remove them early.

FAQs
Does killing one nest attract more wasps?
No, removing one nest does not pull in more wasps. But other wasps may still visit if food and shelter are around. Keep bins closed and clean up spills. Seal gaps to reduce shelter.
Can I block a nest entrance?
No, do not block it. Wasps will chew a new exit and can enter your home through it. Treat the colony instead, or call a professional.
Do wasps reuse old nests?
No, they build new nests each year. The same area can still attract new queens. Remove old nests and seal cracks to prevent a repeat.
Will traps or sprays harm bees?
Sugar and vinegar traps are less attractive to bees. If you spray broadly near flowers, it can hurt them. Use targeted treatments and avoid blooms.
How soon can I use my yard after treatment?
Usually after 24 hours. Check the product label for exact timing. If a pro treated your yard, follow their guidance.
