A few sciarid fly larvae are rarely a problem that belong in the earth like plankton into the water. The earth is more of a problem, and mass proliferation of sciarid fly larvae must be prevented; Below you will learn more about both problem areas:
Mourning mosquitoes and sciarid fly larvae recognize
Adult Mourners see you, small dark flies on a distinct zig-zag course, but you do not see them very long because they only live a few days. These days the sciarids have nothing in mind except reproduction, and besides the pleasant side also laying as many eggs as possible - in the soil of your houseplants belongs.
The haunting flying adults (adult mourning gnats) is over soon, you just do not know for sure whether the large grief-gray horror is growing up in their flowerpots and you have to break out into hectic mourning-fighting.
How to get to the bottom of the threat:
Sciarid fly larvae hatch 4 to 8 days after the black-billed female has laid its eggs, but are once transparent, impossible to see in the potting soil. When they are "big," it does not get much better, still glazed, as long as a matchstick head is wide, and the famous black head capsule - oh stop it, that's a point on the stroke in matchstick width, and who looks his potting already under the microscope? Normal-sighted people need other clues, and they are also available:
  • Slime with silver shimmer on the substrate surface = Mourning mosquito
  • Tiny "lint" on uncovered roots = sciarid fly larvae
  • Tiny "lint" on the surface of completely submerged pots = sciarid fly larvae
Everything is obviously more visible in case of really bad infestation, but if the larvae further down the pot "go to the toilet", maybe there are no mucus threads at all. And very young cuttings can harm the exposure of the roots or a full bath.
In case of suspected sciarid fly larvae you might try to sink a strip of paper at a safe distance from the roots in the potting pot, for example through a stiff straw, the feeding marks on the paper should identify the larvae... but you can do that in principle also let it be the same and hope that this generation of sciarid fly larvae will find enough organic matter in the potting soil, so as not to completely erode the roots, because to combat them you would have to uncover the roots.
Fighting on suspicion

You only have to endure adult sciarids with Torkel flight for a few days (incidentally, the zigzag course during flight should be based on the fact that sciarid mosquitoes simply can not fly very well). Half of the crew can wag their way through the open window to look into the distance, most of the other half lands on the instant yellow stickers. If a few remaining black-billed females are still able to smuggle a few eggs into your potting soil, the following happens: The hatched larvae eat up every organic residue in their flowerpots before they get to the plant roots. If you keep your plants in a self-mixed soil with many organic ingredients, the larvae will find enough of them, until they become again Mourners mosquitoes and thus stop feeding... to the larvae of plastered organic material include mushroom spores in the potting soil, and an occasional purge in this regard does a lot of houseplants very well.
The much-described horrific grief-infestation is a grateful article topic, but for people who have already discovered the diversity of nature, rather scared, but rather normal...
Sciarid-free plant culture
If you pull rare young plants whose roots should better not get to see a single sciarid fly larva, a little more effort is needed, the following options are open to you:
1. Own cultivation soil
If you have an ecologically well-balanced garden, you should assemble your own nursery soil, using the ingredients that such a garden offers:
  • 1/3 compost, very ripe
  • 1/3 cleaned and washed (quartz) sand
  • 1/3 garden earth with rock flour
  • Ev. some charcoal against excessive mushrooming
  • Everything well and mix
You do not need charcoal against mushrooms in a compost that is really mixed with many plants, because the mushroom types in compost produce antibiotics that kill harmful fungi and bacteria. The Institute of Plant Diseases at the University of Bonn found active ingredients against apple scab and salad rot, the University Exeter antibiotics for root rot of beans, white rot of onions, potato brown rot, root and stalk rot, the Institute of Agricultural Research Illinois mushrooms against insecticide resistant flies - who knows what Your compost has everything to offer.
If the plants are later to be placed in pots of self-mixed soil or in the garden, such not entirely germ-free potting soil is the best preparation for the soil, which later expects the seedlings. If the rare seedlings later get a special soil, you can sterilize this seed soil (see 2. below), but the healing ingredients in the compost kill you with it.
2. Purchased cultivation soil

Purchased potting soil (also potting soil) is often interspersed with sciarid fly larvae (you can read in the article "What remedies help against sciarids" about how exactly the sciarids spread over the world). It is usually not really Earth, in the sense of a living defensible organism, but a mixture of (waste) substances (with environmentally harmful peat), which are of material consistency suitable to store water and root tissue stop. In the article "What remedies for sciarid mosquitoes help" there is also a small insight into what may be put into potting soil (and what may be put into it is also put into it), experienced gardeners mix their potting so far as possible.
Cultivation soil with LUFA seal (seal of the agricultural research and research institutes of the countries) guarantees sterility, but no other composition of the earth. So if you read as a tip to prevent the grief of mosquitoes, that you should sterilize the soil in the oven or in the microwave, you can do that: "fry" in the oven for half an hour at 200° or for a quarter of an hour "full load" rotate in the microwave. The larvae are then killed safely, any other useful microbe in the earth also, but really much was in the purchased earth probably not going on anyway.
An earth that is allowed to call itself earth and does not thrive in the sciarid mosquitoes does not exist, would be somehow illogical, because sciarid mosquitoes belong to the most important "producers of earth".
If you want to grow your plants in a "growing medium" (that's the name of the commercially available "earth" mix, presumably the misleading name "earth" is banned there), which mimics "earth," but can not guarantee exactly living functions - It is not logical to buy this substrate first and then kill it completely... Then you could also grow your plants in sterile substrates, which you put together at no cost from your own waste (and the energy for the earth in the soil) Oven you also save):
3. Novel substrates
You are free to grow plants or indoor plants in all sorts of substrates, it does not have to be a commercially available growing medium with potentially dubious ingredients; but also no garden soil, if there is no garden in front of your door. There is currently a powerful movement focused on urban self-sufficiency with unloaded plants. Whenever this cultivation is to take place in the urban living environment, real earth is less well suited than if someone in a rural environment has a garden in front of the door.
Since plants are drawn in a variety of substrates, quite well in waste materials, but usually with less disgusting than body residues from mass animal husbandry - because this whole movement is part of a concept that wants to oppose the escalating madness phenomena of our modern world something and so z. B. against factory farming is.
In the field of urban gardening, the cultivation of plants is generally experimented with. Singapore, with one skyscraper next to the other, the world's highest density population, already covers nearly 10% of its 5.5 million fresh-food needs with vertical farms such as sky greens, and a skyscraper can also wp-content / uploads / 2013/09 / singapore.jpg look.
Hydroculture is plant husbandry in inorganic substrates such as the known expanded clay, but also gravel, basalt, perlite, pure sand, charcoal, coconut fiber or rockwool; The Nutrient Film Technique (NFT) and Deep Water Culture (DWC) drive the substrate even further back, aquaponics breeds fish and crops with little substrate and in a closed circuit, aeroponics can do without any substrate.
If you are concerned with how plants grow "without soil", as a gardener with a garden in front of your door, you learn a lot about the growth of plants. If the house with garden in front of the door becomes a city apartment because of the job, this home gardener may be one of the first to harvest their daily vegetables from the bed on the facade, which they pull up in front of the kitchen window if necessary (vertical methods should be compared to traditional cultivation) to yield ten times higher yields).
You no longer need to fear the scary mosquitoes that starve in inorganic substrates or ungodly cultures...
No chemicals allowed against scary mosquitoes
Because mourning gnomes are relatively unhelpful to useful, can be kept comparatively well without chemicals in tolerable populations and the German citizens are increasingly running against "chemical contamination" storm, are in the house and allotments only products with neem (herbal active ingredient from the neem tree ) authorized.
Even in commercial cultivation, it has become thinner since the authorization for the active substance thiacloprid has been withdrawn for all applications except ornamental plants in the greenhouse due to bee danger. See pre-court-against-bayer-in-dispute-about-bee-pesticides-pesticides,
