Lemongrass is a very robust plant that can be easily cultivated if you live up to the demands of light and warmth. Mourning mosquitoes, however, can seriously damage lemongrass.
The funeral gnat is not hidden from us. If you look closely while casting, sees the small insects fly up. Adult animals are harmless. A problem, however, represent the larvae of the funerary gnome. Even a small injury to the stems is sufficient and the pests can penetrate. The root can also be attacked. That's why you have to be extra careful when casting. The mourning mosquito prefers to lay its eggs in a moist substrate. That's why you should always pour moderately. It is also advisable to irrigate potted plants from below.
The larvae of the black-eared mosquito can generally damage the lemongrass in various ways. Thus, the mourning gnats can cause feeding damage to the leaves and growth damage through an attack of the roots as well as a crippled growth habit.
How do sciarid mosquitoes look like and how do you recognize an infestation?
The Mourning Gnat occurs worldwide. At the same time extreme living spaces are not avoided. The insects were detected in the Antarctic as well as in high mountain regions over 4,000 meters above sea level. Some species live in caves, and others live in the hot desert sun, burying themselves in the sand. Mostly, however, the black-eared mosquito lives in more substantial regions, namely in forests, on pastures or even in the home garden, where it seeks hideouts in the plants and foliage. Even in the flower pot on the windowsill, the sciarids are viable. Therefore, you must control the lemon grass especially during the winter more often.
The Trauermücke belongs to the family of the two-winged and counts, like about 1,800 further kinds, to the subordination of the mosquitoes. In Europe alone there are about 600 species of mosquitoes. The term Trauermücke can be attributed to the dark body and the dark wings. The mosquitoes are about five millimeters in size and have a slim body. The larvae, which are the real threat to the lemon grass, have a light to grayish color and have a fully trained head capsule.
By the way, the sciarid mosquitoes are well recognizable by their slightly prancing flight. The mosquitoes themselves die within a few days and have only the task of mating and reproduction. The larvae can eat mushrooms, bark or leaves. Their excrements turn serve microorganisms as food.
This way you can fight black-headed mosquitoes
The trade offers some pesticides against mourning mosquitoes. However, deltamethrin, magnesium phosphide or pirimiphos-methyl are environmental toxins that are not approved for use in gardens. The inhalation of the substances alone can lead to allergies and irritation of the eyes and mucous membranes. Contact with water can even lead to explosions. These substances are therefore a real danger to children, pets and all living organisms. Therefore, do without the chemistry club. Mourning gnats can also be effectively controlled with natural remedies.
Einsetzen Use yellow stickers against scary mosquitoes:
In the case of yellow or yellow panels, there is talk of color plates that are provided with glue. These panels can be made of paper or plastic. The trade offers different models. Most of the adhesives used are made of polymers. Some products have a coating with polyisobutylene. That's why the yellow stickers appear damp. Less sticky act gel boards, which are provided with hot melt adhesive. These adhesives are harmless to health and are also used, for example, to attach the labels to apples or oranges. Some panels can also be cleaned with gasoline after use and reused. Here more about yellow boards.
You can use the yellow sheets both indoors and outdoors. Yellow stickers for outdoor use should be as heat-resistant as possible and should not contain water-soluble substances. Insects are known to like colors. Especially yellow it seems to have done to them. But there are also stickers in green and blue available, which exert a similar attraction. When approaching the stickers the funerary gnat sticks to the boards. Depending on the size of the plant, several stickers can be used. You should check the plates weekly and replace them if necessary.
Einsetzen Use home remedies for scary mosquitoes:
|quartz sand||If you put quartz sand on the upper layer of earth, the soil appears dried out and the sciarids are kept from laying eggs on the dry ground. Small pebbles can be used as well as bird sand.|
|matches||Put a few matches with the dome down around the plant in the ground, the sulfur-containing components dissolve through the tap water. The larvae die off and the sciarids are prevented from re-oviposition.|
|nutmeg||Nutmeg contains the active ingredient myristic acid as an agent which is comparable in its effect with an insecticide.|
|Carnivorous plants||Placing carnivorous plants (such as the Venus flytrap) near lemongrass will help fight these sciarids. However carnivorous plants are powerless against the larvae.|
Einsetzen Use nematodes against sciarids in the bucket:
A particularly effective and also natural method of combating the fungus mosquitoes are nematodes. These are worms that are invisible to the naked eye and are simply added to the irrigation water. They strike the earth and infest and then kill the grizzled larvae. For this you have to water several times. It may then take a few weeks for all the larvae to be killed.
Prevent infestations with mourning mosquitoes - That's how it works
Since the weeping mosquito prefers to lay its eggs on a damp underground, you should ensure that the earth can dry well after casting. A layer of sand or pebbles also has this effect. Always remove stagnant water from plant pots, as lemongrass does not tolerate waterlogging.
When buying potting soil you should also pay attention to quality. Low-cost products often already show an attack with black-headed mosquitoes. Infested soil should be replaced immediately. You can dispose of the soil on the compost, provided you do not use the compost as a natural fertilizer for indoor plants.
By the way:
Little promising is the method favored by some plant lovers to heat mosquito-infested soil into the microwave for a certain period of time, with the aim of killing the larvae. The Earth also loses important nutrients during this process, which ultimately makes it unsuitable as plant soil.
