It is difficult to find out that thrips in your home are difficult one by one. It's all about the small size of the pest. Insect has a body length of several mm. The color of adult individuals is dark - from brownish to dark gray. Larvae are usually lighter. Recognize thrips can be, if you carefully look at the insect. Their bodies are elongated and divided into segments. Insect paws consist of 2 parts. At the end they have roundish formations similar to suckers. Larvae pest beige. Often they have wings. Also thrips can be recognized by the antennae and large eyes.

The danger of thrips is that their larvae develop in separate colonies. Sometimes they choose one plant. In this case, to spot them among other pots is very difficult.

There are several methods for determining plant contamination. In any case, better stock up on a magnifying glass. Pests are so small that sometimes they are difficult to see with the naked eye.

If the plant has blossomed, then pay attention to the flower itself. The first sign of thrips is peeling pollen. In this case, be sure to study the inside of the bud. To do this, you can gently open it with a toothpick. Another way is to shake the pot over a dark sheet of paper. When infected, you will immediately notice the pest. If there are small worms, then it may be future larvae. Remember that sometimes peeling pollen signals something completely different. It falls on the petals during intense heat or if the plant was transported. Sometimes pollen is a symptom of tick infestation.

Also look for thrips should be on the inside of the leaf plate. When infected, you will see the characteristic point-selection. If the insects have already begun to suck the sap of the plant, then the leaf surface in the affected area becomes grayish. This is due to internal exhaustion. Also in the places where thrips can accumulate, you can see the streaky lines. In consequence, they merge into single spots.

How to save the plant?

Treatment of plants for thrips should be carried out in accordance with the biological stages of insect development. In some periods, the pests are almost completely protected from the effects of insecticides. This happens due to the fact that chemicals enter the body of an individual only during the active stage. For example, they do not affect thrips eggs and during the molting of larvae. During this period, insects do not feed on plants. Therefore, the treatment is carried out not once, but at regular intervals.

Trips on houseplants are treated with any systemic insecticide. First you need to remove all the buds and buds. It is better to do this away from other colors. If possible, move the pot to the street. At the same time you will cause less harm to health by inhalation of chemicals.

Then spraying and spilling. If the pests were found in flowers, then the amount of the drug can be increased by 2-3 times. These thrips are the most difficult. After treatment, the plant is left to dry for several hours. Then it can be placed in a separate room and processed after a certain period of time.

Many flower growers have long established a method of treatment with the help of Aktara and ordinary animal shampoo. In the latter, there should be an ingredient such as permethrin. Aktara is interesting because it is a moderately dangerous insecticide. It works on thrips from 15 to 25 days. Besides, Aktar has no smell.

Treat plants with this drug and shampoo as follows. First you need to prepare 2 solutions. One is for irrigation, the other is for spraying. In the 1st case, we dissolve 1.4 g in a liter of water. Aktara. In the 2nd - also add an arbitrary small amount of shampoo. We process a plant. In parallel, we wash the window sill near the pot with a second solution. Repeat the procedure after a week 2 more times. In winter, we spray and spill the soil after 10 days.

Several features of pest control:

  • After treatment plants need to check all indoor flowers. Trips can be on them after treatment, which will lead to new infections.
  • When treating a plant, first remove the buds and inflorescences. The reason is simple - thrips prefer to develop colonies in them.
  • Try not only to spray the plant, but also to pour the chemical solution into the soil. Pests often settle even there. Sometimes experts advise flower growers to plant it after processing. In this case, it is noted that the roots must be washed from the clods of the previous soil.

Keep in mind that this type of pest has its own phases of development. Therefore, even on a treated plant, after some time, newly hatched thrips can appear. Therefore, it is better to repeat the treatment after some time.

This type of pest is considered one of the most dangerous. The reason is simple - Californian thrips females lay their eggs very deeply in the plant. This reduces the effects of chemicals. This pest looks almost the same as many other species of this class of insects. The size of thrips ranges from 1-2 mm. Adult individuals have wings. Often they settle in well-lit parts of the plant. Calculate them relatively easily. Gray leaves appear on the leaves. Then they merge. Along the edges of the formed sugar rim. Under the influence of the pest buds begin to dry and fall.

They struggle with Western California thrips just as they do with other species. Sometimes pre-set traps. Colored pieces of paper are pasted between the pots, on which substances attractive to the pest (for example, geraniol) are applied. This helps determine the extent of infection. Note that this pest breeds particularly strongly in summer. At low temperatures thrips die.

In order to keep the thrips on the flowers, follow simple preventive measures:

  1. All new plants are quarantined. For this pot is placed in a separate room for a couple of weeks. All this time it is necessary to monitor the state of the plant. You also need to put away bouquets from flowers that you have bought or picked yourself.
  2. Watch for humidity in the room. It is necessary to avoid excessive dryness on very hot days.
  3. Arrange preventive examinations of plants.
