Mosquitoes in summer

Do-it-yourself insect repellent, tips and tricks against mosquitoes – this year in particular, the little creatures are expected to be especially active after the long, damp early-summer period.

First, the most important question: Why do mosquitoes bite some people more than others?

Whether someone gets bitten more by mosquitoes depends on several factors. The CO2 content of exhaled air, individual body odour, skin colour and clothing all play a role. Mosquitoes can detect living beings from more than 100 m away; the CO2 content signals to them that they are dealing with a living creature. They cannot see well, but they react very strongly to contrast. This means white or black clothing is very attractive to mosquitoes. Colours such as pink or light blue are therefore recommended (especially during exercise, when CO2 output is high). The last important factor is individual body odour. Blood sugar plays no role here; what matters is the bacterial environment on the skin. Bacteria and their colonisation break down fatty acids and so create the individual scent every person has.

Last but not least: contrary to popular belief, mosquitoes, unlike moths, are not attracted to light.

So what can you do about these annoying pests?

Insect repellents
Pharmacies offer plenty of choice. It is best to ask your pharmacist for advice based on your skin type and travel destination.

If you would like to make your own mosquito repellent:

Base blend

• 4 drops thyme linalool
• 8 drops lemongrass
• 4 drops lavender
• 4 drops peppermint
• 2 drops tea tree oil
• (Optional: 3 drops lemon eucalyptus)

Roll-on: Mix 10 drops of the base blend with 15 ml carrier oil

Spray: If you prefer a spray, mix 10 drops of the base blend with 1 tablespoon witch hazel or 2 tablespoons vodka and 45 ml water in a spray bottle. Shake well before use.

Additional tips

• Wind: a small fan can help blow the insects away and makes it harder for them to pick up body odours.
• Showering: sweat in particular attracts mosquitoes. It is therefore a good idea to shower before spending time outdoors at dusk. Using perfume, fabric softener and sweet-smelling deodorants sparingly is also recommended.
• Garlic and vitamin B: are said to help produce a scent that mosquitoes find unattractive.
• Clothing: Light-coloured, looser clothing also offers better protection, as mosquitoes prefer dark, tight-fitting fabrics.
• Insect nets: fitted to windows or around the bed can also help.

What if you have been bitten anyway?

It itches, but what can you do? Home remedies for the itch: place a slice of lemon or half an onion on the bite. Cucumber slices, calendula ointment, tea tree oil and aluminium acetate gel also relieve itching. And of course any form of cooling, such as a damp cloth or cooling patch.
