Red Spider, dangerous parasite, among the most dangerous and unwanted by plants and those who love them, given its high potential for infestation. This arachnid, mainly phytophagous, affects both fruit and ornamental plants and is able to reproduce very quickly, even within a few days, and generously. But it can be partly prevented, and fought, even with natural remedies.

Ragnetto Rosso: what it is

The Red Spider is a very small mite, in fact it is called "spider" can measure even just half a millimeter, in length, if females and, strange but true, males are even smaller. This terrible enemy, of plants and of us green thumbs, is red when in the adult stage but as a teenager it appears yellow or orange.

There are two different species, the one called Panonychus Ulmi and that call Tetranychus, the latter is also distinguished by the absence, on the sides of the back, of some white bristles that the Red Spider of the first category is proud of while destroying plants. This mite lays eggs, deposits over a hundred of them every year, and is therefore an insect of the oviparous category. To find out more, I recommend the article “Oviparous and Viviparous”.

To grow and feed, it eats the upper and lower edges of the leaves and shoots with its horrible pointed mouth with which it literally manages to "sting" the vital parts of our plant sucking nutrients.Vampire, this arachnid.

Red spider: remedies to remove it

The Red Spider, given that it is harmful and annoying, it can be removed with splashes of water because its presence is closely linked to a matter of humidity. The more the environment around the plants is humid, the more the Red Spider stay away. It is therefore easy to say that it is necessary, for the good of our plants, to increase irrigation, especially if they are particularly hot and dry days.

Leaves and shoots kept well wet and sprinkled may certainly not feel 100% safe but a little more than others. This also explains why when the climate is very arid the crops are ad high risk of infestations which become large enough to be included in the list of “horticultural” calamities.

Red spider in the house

If we have plants in the house that give bad signals but we are not sure that the culprit is our enemy Red Spider, here are some notes to recognize it. This mite mainly loves to affect the leaves: we see them discolor suddenly and all of a sudden, without understanding why. He knows why he turns the bright leaves of a healthy and cheerful little plant into leaves with the bronze upper margin, even dry until the final fall. Of the leaf.

The Red Spider it can also cause the appearance of whitish spots which are explained as residues and droppings of the larvae. It is not a good sign at all, if we see it: it is the unequivocal sign of colonization that has taken place. The Ragnetto won.

Spider Red tomato

The two varieties of Ragnetto the victims are divided, which are both herbaceous and shrubby plants, up to vegetables: the Tetranychus Urticae he prefers tomatoes, beans and various other legumes, and soy. The Panonychus instead he devotes himself to annoying fruit trees and grapevines.

The tomato, therefore, is the favorite of the species Tetranychus, when it falls prey to this annoying mite, it shows a sort of burn effect on the leaves. Not protected by the leaves, in turn i tomatoes are burned from the sun's rays that manage to hit them fully and for a long time.

Red spider of travertine

The good double of the little red spider and this Travertine spider: they look very similar physically but the second is completely harmless. It is called so, "del travertino" because it hangs near and on stone walls and stony ground. We must not stone him, however, because in the misfortune of looking like a very bad animal, he is totally innocent, he does nothing to plants or to man.

The only ones who have to shy away from it are some insects, eaten by it Travertine spider both from larvae and from adults. There is only one reason to be angry with this double: it dirty a lot and forever: if crushed it leaves stains that persist even on the stones.

Red spider and citrus fruit

Citrus fruits like both al red weaver spider (what we have more seriously called Tetranychus urticae) both al red spider said of the citrus fruits which is then the Panonychus citri. Both, deployed aggressive in colonies, attack defenseless shoots above all by pinching them on the underside of the leaves and along their ribs, causing them to lose their beautiful original color.

The danger Red spider for citrus fruits as for many other plants, it increases when we are in hot and dry climates, the only remedy is to use specific acaricidal products, or to try biological struggle.

Red spider: biological struggle

If we are faced with a rampant infection, we must give up for the sake of our plants and start a chemical fight to chase away the Red spider, but if it's not a dramatic situation yet, then let's try the natural fight. This strategy focuses on the predatory insects of this mite, above all others mites or ladybirds. Less harmful than chemical herbicides, we can also find online, a pack of 250 chrysopa larvae, or 500 eggs, to be unleashed against the Red spider.

As we have already seen, we can also try with natural "soft" methods of struggle such as splashing water on the infested parts because the Red spider hates water, but we do not trust in great results if the colonization is too extensive, and remember that this method certainly does not eliminate the eggs but only the Adult red mites.
