Black bug in the vegetable garden
This insect is very voracious: this is why it is better to remove it from the garden. If you have ornamental plants, it may end up in your house too. With its sucking apparatus it quickly empties the plant cells causing serious damage to the plant.
THEsymptomsof an infestation fromblack bed bugsthey are various and depend on the extent of the infestation itself. From small alterations of the leaf surface to more serious breaks, splits, yellowing of the leaves, vegetative decay to even affect the fruits where surface alterations are visible.
ThisAsian parasiteit affects many plant species, including fruit trees and open field crops (such as soy, corn, sunflower fields ...), it attacks many common horticultural species such as tomatoes, peppers and legumes.
With our climate, fortunately, it is able to perform one reproductive cycle per year. In the country of origin it takes between 4 and 6 generations. The real problem is that being an "alien species" on our territory there are not enough natural predators able to decimate it. Insectivorous birds able to prey on it are discouraged from approaching agricultural fields due to pollution and the massive use of pesticides.
In our garden, theblack bedbugit is most active between July and September.
Black bedbug in the house

The black bug in the house should not cause you to be alarmed: this plant is harmful to the garden but does not attack humans. Of course, it is not pleasant to have plant parasites in the house, however, it becomes easy to remove it even mechanically.
How to get rid of the black bug
The colonies of black bed bugs they can reach important densities. Every single colony can give rise to large invasions that are difficult to manage in the garden. Due to this feature, theAsian bedbugit is considered a potential threat to local agriculture.
Each colony is made up of dozens and dozens of individuals and, under favorable conditions, infestations can reach even more impressive numbers.
For the treatment ofblack bedbugthe chemical fight with ad hoc pesticides is foreseen. As always, we support the use of natural remedies such as the use of a liquid solution given by water and natural Marseille soap. Prepare a highly concentrated aqueous solution to spray on infested plants. After 30 minutes of action, sprinkle water to rinse.
I remind you that like any water-based treatment, this too must be done away from the hot hours: perform the treatment early in the morning or in the evening.
Among other natural chemical remedies you can use againstAsian bedbug, there is neem oil which has an intense antiparasitic action, very useful in the vegetable garden. Neem oil is widely used in agriculture.
If you buy pure neem oil, remember that it must be diluted in water before use. Where to buy neem oil? At agricultural consortia or by taking advantage of online sales, for the various proposals and to find out the price and opinions of farmers on neem oil, read the user reviews on "this Amazon page".
