There’s nothing like firing up the grill or lying out a picnic blanket under the summer sun. Whether it’s a backyard BBQ with friends or a peaceful lunch in the park, outdoor gatherings are a highlight of the season. But just as you’re ready to dig into your favourite dishes, a buzzing intruder shows up—wasps.
These uninvited guests aren’t just annoying—they can be aggressive, persistent, and even dangerous for those with allergies. The good news? With a little planning, you can keep your BBQ or picnic wasp-free and enjoyable for everyone.
Why Wasps Love Your Picnic
Wasps aren’t crashing your BBQ just to be rude—they’re on a mission. These buzzing scavengers are naturally drawn to the things that make your picnic appealing.
- Sugary drinks like soda, fruit juice, and sweet cocktails are wasp magnets. The sugar provides quick energy for their active foraging.
- Grilled meats are packed with protein, which wasps collect to feed their larvae back at the nest.
- Bright-colored outfits, floral prints, and scented lotions or perfumes can easily confuse wasps, making you look like a walking bouquet.
As summer progresses, especially from late July to early September, wasps become more aggressive and desperate for food. Their colonies are at peak size, and natural food sources become scarce, making your outdoor spread the perfect target. Understanding what attracts wasps is the first step to keeping them away. Next, let’s look at the common mistakes that might be accidentally inviting them to your event.
Mistakes That Invite Wasps
Even the best-planned picnic can go south if a few small details are overlooked. Wasps are opportunistic, and certain habits or setups can unintentionally roll out the red carpet for them. Here are some common picnic mistakes that practically invite wasps to join your meal:
- Leaving food uncovered: An open fruit bowl, meat platter, or dessert tray is an irresistible buffet for wasps. Once they find it, they often return—and bring friends.
- Throwing food waste into open trash bins: Leftovers, sticky plates, and sweet wrappers tossed into an exposed garbage can quickly become a wasp magnet. The smell alone can draw them from a distance.
- Wearing floral-scented perfumes or lotions: While you may love that summery fragrance, so do wasps. Scents that mimic flowers or fruit can confuse and attract them.
- Wearing bright, patterned clothing: Wasps are visual hunters. Bright yellows, oranges, and floral prints can make you look like a giant flower—and a target.
Avoiding these common mistakes can drastically reduce your chances of a wasp invasion. But to enjoy a peaceful, sting-free gathering, you’ll need to take proactive steps before the event begins.
Pre-Picnic Prevention Tips
The best way to stop wasps from invading your BBQ or picnic is to keep them from showing up in the first place. A few simple precautions before guests arrive can make all the difference between a relaxing afternoon and a buzzing nightmare. Here’s how to prepare:
- Set up citronella candles or torches: The strong citrus scent naturally repels wasps (and mosquitoes, too). Place them around your seating and food areas for a safe, effective barrier.
- Place wasp traps far from the eating area: DIY or store-bought traps lure the pests from where you’re gathering. Position them at the far end of your yard or picnic site to redirect attention.
- Prepare food covers and sealed containers: Mesh covers, lids, or even upside-down bowls can shield food and drinks from wasps while still keeping them accessible for guests.
- Avoid sugary marinades if possible: Sweet sauces like honey BBQ or teriyaki are tasty, and wasps, if you can, go for savoury or herb-based options to reduce attraction.
- Keep drinks in closed bottles with lids. Wasps love sugary beverages and can slip into open cans or cups unnoticed. To prevent unpleasant surprises, serve drinks in bottles with caps or use cup covers with straws.
Taking these steps before your event starts will create a much less tempting environment for wasps—and a far more comfortable one for your guests.
During the Picnic: How to React
Even with the best preparation, a wasp or two might still sneak into your outdoor gathering. How you handle their presence can distinguish between a minor annoyance and a full-blown panic. Here’s how to keep things calm and under control if wasps show up mid-picnic:
- Don’t panic or swat aggressively: Sudden movements can trigger defensive behaviour in wasps. Stay calm, move slowly, and avoid swatting—this can make them feel threatened and more likely to sting.
- Keep a handheld fan or diffuser nearby: Wasps dislike moving air. A small battery-powered fan or essential oil diffuser (especially with peppermint or citronella) can gently steer them away from your space without provoking them.
- Assign someone to monitor trash disposal: Overflowing garbage is a wasp hotspot. Have someone regularly tie up and seal trash bags and place them away from the eating area.
- Quickly wipe up spills and crumbs: A little soda spilled on a table or a sticky juice ring on a cup can quickly attract wasps. Keep paper towels and wipes handy to clean as you go.
Staying alert and calm during your picnic will prevent wasps from getting too comfortable and keep your guests relaxed and safe.
Natural Wasp Repellents That Work
If you prefer to keep your outdoor gatherings chemical-free, you’re lucky—nature offers some powerful tools to help keep wasps at bay. These DIY, non-toxic remedies are safe for people and pets and surprisingly effective at deterring unwanted winged visitors.
- Peppermint oil spray (DIY mix)
Wasps strongly dislike the smell of peppermint. Mix a few drops of peppermint essential oil with water and a splash of dish soap in a spray bottle. Spritz it around picnic tables, seat edges, and food prep zones. - Clove, geranium, and lemongrass oil blend
This powerful trio is proven to repel wasps. Add 10 drops of each oil to a small diffuser or mix with water in a spray bottle. It smells great to humans, but not to wasps. - Vinegar and water trap
Mix equal vinegar and water in a bowl or jar, and add some sugar. Cover with plastic wrap and poke small holes in the top. Wasps crawl in for the sugar and can’t escape. - Fresh cucumber slices
Wasps hate the bitterness of cucumber peels and flesh. Place a few slices around serving trays or near drinks as a natural, scent-based deterrent.
These natural repellents are easy to make, affordable, and highly effective—especially when combined with smart preparation and real-time awareness.
When to Call a Professional
While DIY solutions work well for occasional wasp visits, there are times when it’s safer—and smarter—to bring in the experts. Knowing when to call our professional can protect your health, prevent property damage, and give you peace of mind.
- Signs of a nest nearby
You likely have a nest on or near your property if you notice a steady stream of wasps flying in and out of a specific spot (like under a deck, in a tree, or a wall crevice). Do not attempt to remove it yourself.
- Large swarms gathering repeatedly
A few wasps are normal. But if dozens keep returning to the same area, it’s a sign of a nearby colony—and a professional inspection is crucial.
- If someone in your group is allergic to stings
One sting can become a serious medical emergency for someone with allergies. If you regularly host outdoor events and someone is at risk, professional wasp control is a smart preventive step.
