Griefs are not among the most dangerous pests, but their tanning can cause mischief. The good news is that there are several solutions to get rid of this annoying insect. For some, we are not even dependent on chemistry or other interventions that could endanger our crops or health.

We encounter small black insects, which make our lives uncomfortable with their constant flying, especially where there are houseplants and greenhouse plants. The more plants in the home or greenhouse, the greater the chance of the presence of this pest. The mourners choose flower pots for their temporary home, from which they set out for regular raids. However, apartments and greenhouses are not the only places where they are used to living. Some species also feel good in the garden.

How do we recognize sadness?

  • These are small black flies, 2 to 4 millimeters in size.
  • Black box headers are a typical feature.
  • Thanks to 2 pairs of wings, they can fly tirelessly.
  • The larvae are slightly larger, they can be 7 millimeters long.

How does sadness get to us?

In the vast majority of cases, saddle transfer is caused by the purchase of substrate. A clever little insect lays eggs in it, from which the larvae hatch very quickly and adults fly out of them after about 2 to 3 weeks. We unknowingly bring home sadness ourselves. Under suitable conditions, such as higher humidity, we can inadvertently attract them without buying a substrate. They first arrive at a household where many houseplants are grown.

Where do sadness’s do best?

  • In rooms with cultivated seedlings and houseplants.
  • In closed greenhouses, where a higher temperature is maintained.
  • The larvae have the best conditions in humus substrates.
  • Wet to soaked soils are especially suitable for the multiplication of mourning.

Damage is also done by larvae and adults

Flying an adult is far from the only problem that sadness causes. Although they can transmit pathogens of various harmful fungi to plants by flying, they are not as dangerous compared to larvae. It is the young larvae hidden in the clay that reach the roots of the plants, which persistently bite. They can damage them to such an extent that nutrition stops flowing to the plants, which makes them much more prone to fungi and other diseases.

How to eliminate grief without chemistry?

There are several non-chemical solutions to eliminate grief. However, their effect may not be 100%. Griefs are quite difficult to eliminate and, in most cases, leave the temporary home only when they do not have any pots with clay and plants where they could continue to reproduce.

Use of parasitic nematodes

The use of parasitic nematodes is one of the most proven biological methods of eradicating mourning. The whole method consists in infesting the larvae with these nematodes. These enter their body through the respiratory or digestive openings and gradually kill them.

Drying of the substrate in the oven

While parasitic nematodes are used in the already identified presence of mourning, the drying of the substrate is approached as a precaution against them. This can be done by heating the soil in a baking oven or in a microwave oven, where the larvae hidden in the clay will be killed. At the same time, the substrate dries a little, which will make it less attractive for mourners.

Irrigated with caustic soda

Stinging nettle can be used in various ways. When applied to a substrate in a pot, it serves as a biological disinfectant. The extracts of nettle in such a lye are very toxic to the larvae of mourning. At the same time, they also have a repellent effect on adults, which will thus avoid planted plants or seedlings.

Insect stickers

Traps in the form of adhesive labels are not entirely non-chemical, but at the same time they cannot be classified as harmful methods based on chemistry. Their goal is to attract mourners to a hung or loosely placed label coated with a layer of glue, to which they stick and no longer fly off.

How to mourn by chemical spraying?

Even the use of chemical sprays is not 100% effective, but in the case of an overgrowth of sadness, it becomes a last resort. In addition, in the production of higher-quality sprays, the composition of the substances used has been taken into account for a long time. The individual preparations are thus less harmful to plants from year to year.

Non-traditional methods of disposal

In addition to the above methods, there are also lesser-known folk tricks that also bring the desired effect. In some cases they are not the healthiest, in others the emphasis is on the healthiest and most gentle disposal based on “bio”.

  • Flushing the soil with a solution of hydrogen peroxide.
  • Pouring the liquor into the substrate, which suffocates the mourners.
  • Insertion of garlic repellent cloves into the substrate.
  • Cut the potato and place its half in the pot.

When observing sadness in the apartment or in the greenhouse, it is recommended to intervene as soon as possible. There will be other individuals in the space and it is only a matter of time before they start flying. It is necessary to act immediately, especially because of their rapid reproduction. Although females live only a few days, they can lay dozens of new eggs in a short time.

Preventive TIP at the end…

The transfer of grief in the purchased substrate can be avoided by choosing a suitable type of soil. Not all substrates are suitable for annoying insects. For example, they do not stay at all in the organic coconut substrate. They have a problem withstanding even in soil with a higher concentration of peat. Quite effective in protecting the soil from mourning is also the classic manure, but only if it is not too moist.
