How to get rid of cobweb and shell mite on orchids

Pest Description

To learn how to help orchid in the fight against pests, it is worth knowing the types of parasites. The use of the right actions and preparations saves the flower from death.

There are 2 types of pests that can start on the phalaenopsis. The first is a carapace tick, and the second is a spider mite or flat-bodied. Spider mites on the orchid pose a threat to the life of the flower, and shell mites harm indirectly, because they feed on the substrate.

Spider web

Spider mites are so small that it is difficult to replace how they appeared among the leaves. Adults are 0.1-0.3 mm long and look microscopic. Among the signs, white and gray, yellow with brown spots or pure white are also distinguished.

The main habitat of pests is the reverse side of the leaf, on which it is easier for them to gain a foothold and not fall when watering. They lay eggs on green leaves, although they move throughout the plant. Masonry is done along the veins on the sheet, from the inside. From the masonry, white paths are formed. Spider mites crawl slowly along the flower, mostly they spend time immobilized.

The first sign of the appearance of ticks of this kind on the phalaenopsis are white dots and a small web. A white coating forms on the inside of the sheet. Often an orchid is infected from other flowerpots with flowers or with a pest entering through a window. It multiplies rapidly, because the period of full development is from 4 to 6 days.

Panther mites on orchids are not uncommon, you need to deal with them urgently: a bug quickly destroys the plant.

The body of the shell mite is colored red, brown, sometimes almost black. Its length is 0.7–0.9 mm. The pest moves quickly, does not like bright light. He runs all over the plant, but lays eggs on the dead parts of the orchid, rotten roots and branches.

Bugs give preference to damp, moist soil. They grow to a fully adulthood over a period of 3-4 weeks to several months.

They do not eat the living tissue of flowers, but feed on a substrate, fallen leaves and petals.

The carapace tick carries helminth and nematode eggs, fungus and bacteria.

Methods of struggle

The approach to combating tick species is unique. The plant will have to be treated not only for pests, but also for the ailments that they carry: bacteria, fungi.

Fight against spider mites

To get rid of the spider mite on the orchid, the flower pot is taken out to the balcony or loggia: you need good access to fresh air. The stem, foliage and buds are treated with an acaricidal or insectoacaricidal agent from a spray. To enhance the action of the solution, the stem with leaves is wrapped in a package for several days, reducing the flow of oxygen to insects. It is impossible to overheat the pot: this is fraught with the appearance of root rot.

Control measures include getting rid of larvae. The preparation for adults does not harm the eggs and newly hatched individuals; therefore, the control procedure is repeated at least 3 times with an interval of 4-5 days. Next, orchids are treated with a fungicidal solution in case the pest has managed to infect the plant with a fungus.

Methods of dealing with different types of ticks

Fighting the Shell Mite

To cure a flower from an armor-mite, the first step is to remove the old substrate: the root tick on the orchid lives there. Then the orchid roots are cleaned of the remaining ticks. Using chemicals, they process the roots, stem and leaves, soaking them in a solution of acaricide. To remove the carapace tick on a flowering orchid, apply:

  • Fitoverm;
  • Nisoran;
  • Vermitek.

After falling asleep, fresh substrate and transplanted a flower.

The application procedure is repeated after 2 weeks, alternating drugs: so the tick does not have time to adapt. When replacing the substrate, treatment with antifungal agents is not required.


You can not be afraid of pests in phalaenopsis if you take preventive measures.

To prevent the appearance of an armor tick, the soil in the pot is periodically dried: the pest prefers a moist, moist substrate.

Pest Prevention

When spraying orchids monitor the amount of moisture that has fallen on the leaves. Excess water collected between the stem and leaflets in the sinuses is wiped with paper towels or cotton pads. Controlling the humidity of the substrate within the optimal norm, exclude the presence of root rot, and the carapace mite on the orchid eats precisely dead particles of the plant. Maintaining cleanliness in the pot, while removing the fallen leaves and petals, the possibility of the appearance of oribatids is excluded.

The spider mite on the orchid, unlike the carapace, prefers warm places with low humidity. In apartments with central heating, the air is often overdried to a level of 35-40%, which increases the risk of pests.

Be sure to monitor the degree of humidity in the substrate, develop a schedule of watering and spraying. One of the simplest methods of prevention is wet wiping of the petals and the stem of the orchid.


No one gives guarantees that the orchid will never encounter pests at home, but the treatment started on time easily eliminates the pest. To avoid problems, they use preventive safety measures, observe all care regimes, and control the indoor microclimate. As a result, one does not have to be afraid of the appearance of a red carapace tick on orchids.
