Garlic kills fungus gnats
How does garlic work against the fungus gnat?
When you heard that the cloves can be used against the fungus gnat, you probably first thought of the strong smell of the garlic bulb. However, the aroma hardly plays a significant role in combating it. Rather, it is the allicin it contains, which not only drives away the pests, but kills them.
Allicin is a sulfur-containing acid found in high concentrations in garlic. It has a toxic effect on the fungus gnat.
application
There are two ways of releasing the allicin it contains:
version 1
- Cut off the tip of a clove of garlic with a sharp knife.
- Stick the entire bulb into the substrate of the affected plant.
Variant 2
- Peel a garlic bulb.
- Separate each toe from one another.
- Then roll them.
- Spread the garlic cubes over the potting soil.
How effective is garlic?
Compared to other home remedies against the fungus gnat, garlic is only recommended for a minor infestation. The allicin content of each individual garlic bulb is subject to natural fluctuations. The substance is not always present in such a high concentration that it really kills all the little animals. If the application does not bring any visible success, you should combine the garlic method with other home remedies against the fungus gnat. It is important that you always choose biological methods. Chemicals not only harm the fungus gnats, but also your plant.
