Mosquitos should be eliminated

Five tips: How to drive away and control mosquitoes

High temperatures and rain alternate this summer. In the humid climate, the mosquito larvae have ideal conditions to develop. As soon as it is warm, they hatch. Anyone who is outdoors in the evening can hardly avoid the swarms. With simple means you can drive away mosquitoes. But be careful: Certain mistakes make the nuisances multiply even more.

Mosquitoes love small and large stagnant bodies of water, regardless of whether they are on the banks of the river, bathing lake or the rain barrel. Even water residues in the watering can serve as a breeding ground for the insects. In order to keep the populations in your own garden as small as possible, you should not leave any residual water open. This prevents the mosquito from laying its brood in the immediate vicinity.

Biological mosquito control with Bti

Tablets containing the active ingredient Bacillus thuringensis israelensis (Bti) can be used so that the rain barrel does not become a hotbed. The microbiological agent is available both in tablet form and in liquid form in hardware stores or specialist gardeners.

Since only certain mosquito species react to the agent, no other animals or even people are harmed. Bti is even used for large-scale mosquito control in nature reserves. The water from the domestic rain barrel can then be used for watering without hesitation.

Successfully drive away mosquitoes - five tips

  1. Some mosquitoes are attracted to dark blue and black. Prof. Thomas Löscher from the Professional Association of German Internists therefore recommends lighter, wider clothing.
  2. Anyone who uses personal repellants should choose products that contain around 30 percent of the active ingredient DEET (diethyltoluamide). They last four to five hours, after which they should be renewed. According to Löscher, they can prevent 90 to 95 percent of mosquito bites.
  3. Test.de names the active ingredient Icaridin as an alternative to DEET. This is also contained in many mosquito repellants.
  4. So that mosquitoes do not even get into the house Insect screens a good solution. Even simple nets that are attached to the window frame with Velcro can hold for a few euros insects remote.
  5. Home remedies such as essential oils and fragrant plants are controversial. Some swear by the natural defense, others consider it useless. Tomato plants should help, Fragrant pelargoniums and Catnip. The scent of lemons and lavender is also said to drive away mosquitoes.

What remains ineffective against mosquitoes

  • According to Stiftung Warentest, ultrasound devices and UV lamps have no effect.
  • The same goes for defense bracelets.
  • Stiftung Warentest also advises against using biocide vaporizers. The electricity-operated devices evaporate insecticides - this works, but can also be harmful to people and pets.

Some people prefer to bite mosquitoes

That is actually true, confirms Martin Geier, a biologist from Regensburg who has been researching the behavior of mosquitoes for many years.

The smell of the skin is responsible - everyone smells different, and mosquitoes have a fine nose for this. The mixture of substances such as lactic acid, ammonia and fatty acids is the decisive factor in whether a person is preferred to be stung or not. There is little you can do about it. Even showering only helps temporarily because it only conceals the body's own odor for a short time.

In some cases, however, you can take countermeasures: Warm skin, for example, is more likely to attract mosquitoes, says Geier. After exercising outdoors, it is better to take a quick shower or cool off in the lake.

Better not be the stale bread for mosquitoes

Mosquitoes are only really picky when it comes to groups of people. If you are never bitten among people, that doesn't mean that mosquitoes generally disdain you. This can be compared to hungry people: if there is a large selection of food, only eat what you like. If there is only dry bread, you will eat that too.
