It’s that time of year when wasps whizz about, stressing out unsuspecting diners in restaurants and gardens. Here’s why wasps are so numerous right now and what you can do to banish them.
Lovely! I’m sitting at a patio bar with a cold Coke and a juicy saltimbocca, looking forward to an enjoyable evening. Unfortunately, I’m not the only one with that idea. As I take my first bite, I’m joined by uninvited guests: wasps.
The gall! There they sit, right in the middle of the piece of meat on my fork, and refuse to budge. The waiter tells me that someone’s been getting stung almost on the daily lately, «even in the mouth». I can’t say I’m surprised. Wasps are particularly intrusive in late summer. So, it’s high time for a few tips for dealing with the pesky buggers that you can also use at home.
Plants such as lavender, mint and lemon balm are also beautiful and functional table decorations. Herbs with a strong scent, such as basil or oregano, also act as a wasp deterrent. Surprisingly, the same goes for the tomato plant. It exudes such an intense odour that is even said to repel mosquitoes.
Of course, you could go for the straightforward solution: pesticides. But this is best left to the professionals. Nests in particular can quickly become dangerous for us laypeople. Traps are also only recommended to a limited extent, as they usually only attract older wasps and will hardly decimate the active population.
Natural deterrents are preferable, except in extreme cases. As much as you may not like to hear it, wasps are, in fact, useful. They eat flies, mosquitoes, spiders, caterpillars, aphids and numerous other pests. And they themselves are food for birds and various mammals. They also recycle dead animal material and pollinate plants in search of sugar.
Here are some tips for how to coexist as peacefully as possible and avoid getting stung.
If you do get stung by a wasp regardless, it’s important to act quickly – especially if you were stung in the mouth or throat area, which can swell up and hinder breathing. Suck an ice cube, wrap your throat in a cool compress and consult a doctor to be on the safe side. In the event of an allergic reaction, grab an adrenaline pen and call an emergency doctor stat.

I love anything with four legs or roots - especially my shelter cats Jasper and Joy and my collection of succulents. My favourite things to do are stalking around with police dogs and cat coiffeurs on reportages or letting sensitive stories flourish in garden brockis and Japanese gardens.

Show allYou’re likely familiar with oranges studded with cloves from Christmastime. What smells heavenly to most of us is reportedly an olfactory nightmare for wasps (link in German). You might therefore want to try placing some citrus fruits on your garden table. Hey, it looks just as pretty four months before Christmas.
Speaking of fragrances, essential oils reportedly also repel (link in German). In tests, clove, lavender, mint, rosemary, thyme, lemongrass and tea tree have proved particularly effective. You can use a fragrance lamp or an electric diffuser to waft the fragrance about. Besides, lavender oil is said to have a calming effect and reduce stress in humans.
Coffee grounds aren’t suitable for the table, but you can place them nearby. Put them in a fireproof bowl and light them, and the wasps should disappear. Mind you, experts such as the biologist and wasp researcher Lars Krogmann (link in German) say this only helps to a very limited extent.
Students at «Jugend forscht», which encourages young talents in STEM, made the discovery that overripe grapes are a real magnet for wasps. You can place the fruit at a safe distance away and combine it with pears and a jam of your choice. But treat this tip with caution; you run the risk of attracting even more wasps. What’s more, it’ll take one to two weeks for the wasps to accept the grapes as an alternative feeding place.
