House flowers are not immune to pests. Thrips are considered frequent guests in the apartment. They are omnivorous insects, so they live on a variety of plants in the house. It is necessary to fight them without slowing down, as they actively reproduce. Let's consider what remedies for thrips on indoor plants are used at home.

Thrips - who are they?

Insects that grow on average to 1.5-2 mm, with an elongated body and wings, are thrips. There are more than 6,000 different species. All of them are omnivorous insects, and all indoor plants in an apartment or private house suffer from their appearance. They lead an active lifestyle in summer and winter. Thanks to the presence of powerful wings, they easily move from one flower to another and are able to carry infections that are dangerous to plant life.

These pests belong to sucking insect species. Thanks to their proboscis, they easily pierce plant leaves or young shoots and suck out the juice. They reproduce by laying eggs; they consider the underside of the plant leaves to be a secluded and safe place. It takes 1.5 months for one larva to grow to adulthood. After which the adult lives for another month.

Thrips on indoor flowers are divided into several types, but you won’t be able to determine which one has settled in the house on your own. This will require the help of an experienced insect specialist. But to combat thrips, it is not necessary to know the exact species. After all, all means are designed to combat the general class, and not individual subspecies of insects.

Causes of thrips

The main question most often asked by home flower lovers is the following: where do thrips come from on indoor plants? A list of reasons why they may appear is given below:

1. Thrips prefer poorly ventilated areas. They consider musty rooms to be a favorable environment.
2. They are attracted to rooms where the air temperature is 24 degrees Celsius or higher.
3. When a new plant appears in the house, it must be carefully inspected. If the plant has been infected, then rapid reproduction of thrips will not take long.

Insects can get into the house from the street on any plants or clothing. If you have your own summer cottage, you should treat all plants more vigilantly. In summer, it is recommended to inspect plants for possible pests at least once a week.

How to recognize thrips in the house

It is difficult to recognize thrips on indoor flowers at an early stage. They are almost invisible because most of the time they live on the underside of the leaves. Due to the fact that they drink juice from domestic plants, visible changes occur in the structure of the leaves, and in general their condition worsens:

• pale stripes appear on the surface of the leaves, they are located in a chaotic order;

• small circles with holes form on the leaf, from which thrips drank juice;
• black clogged areas are easily visible on the leaves - pest feces;
• damaged leaves and flowers wither and fall off;
• young shoots of an infected flower become distorted.

Thrips reproduce quite quickly; one individual can lay up to 300 eggs.

The sooner you can apply a thrips remedy on indoor plants, the greater the chance that the plant will not die. There are ways that can help recognize pests on plants:

• Take a white piece of paper and carefully shake off the leaves of the flower over it. If the plant is infected, there will be adults or larvae on the leaf.
• It is recommended to carry out a visual inspection of the plant with a magnifying glass. This method helps to identify pests at an early stage.

It is necessary to carry out timely treatment with anti-thrips agents on indoor plants, without giving a chance for further reproduction.

Set thrips traps. They are made from a colored sheet of paper with a layer of glue applied to the top side of the sheet. They need to be placed close to the flowers, no higher than 1 m above the ground. Blue or yellow paper is suitable for traps.

Preventing the appearance of thrips on flowers

The earlier a pest is detected, the more likely it is that simple remedies will help deal with it. Before any event, diseased plants are separated from the rest and quarantined. The remaining flowers are carefully examined. It would be useful to sanitize the place where the flowerpots stood. This is usually done with a household solution. soap Even if there are no visual traces of the presence of thriposv, the top layer of soil (2–3 cm) is removed. Parasite eggs may already be laid there.

Observe precautions:

1. Keep newly purchased flowers separately for at least 2-3 weeks (this will keep your home collection healthy).
2. Once every 7-10 days, bathe all plants under a warm shower (this will help get rid of not only dust, but also possible mites, aphids and other pests).
3. Excessive dry air creates “resort conditions” for the reproduction of insects.
4. Regular inspection of indoor plants (do not forget to look under the leaves and at the very roots).

Advice. Gesneriaceae (Saintpaulias, Streptocarpus, Gloxinias) are bathed “head down”. The plant with the pot is turned over so that water does not get into the outlet. Lightly hold the soil in the pot with your fingers.

Pest control methods

At the first sign of thrips appearing on indoor plants, you have to act immediately. If you postpone the control process, there is a risk of their numbers increasing and affecting more house plants. At an ideal room temperature (22-25 degrees Celsius), they will reproduce within 6 days and double their numbers.

Thrips love flowers with blue buds. Their favorite types of flowers are:

• peonies;
• chrysanthemums;
• violets;
• ficus.

The main primary ways to get rid of thrips on plants is to quickly react and make immediate decisions:

1. Isolate all infected plants. It is recommended to transfer flowers without unnecessary shaking, so that the larvae do not fall from the bush.
2. Wash the plants - this is done with a warm shower.
3. Remove all flowers and buds from the plant. It is in these places that thrips prefer to lay eggs.
4. To get rid of larvae in the soil, it is better to remove the top layer of soil or replant the plant in a new post. When replanting, it is recommended to thoroughly wash the flower's measles system.

Having identified the flower varieties most often susceptible to infection, they can be divided in the table according to the favorite habitats and breeding places of thrips. Thanks to this information, it is easy to recognize thrips on indoor plants at an early stage (photos and the fight against them are described below).

After the initial steps have been completed, the plants should be treated with chemicals.

Preventive measures

In order not to have to deal with thrips on the very first day after purchasing a plant, it must be chosen very carefully. Arriving home, he should be placed in a separate room and his condition monitored for two to three weeks. To prevent pests from spreading to other plants in your home, you must regularly carry out the following activities:

regularly inspect plants, paying particular attention to potential signs of pests; maintain optimal humidity in the room; keep sticky traps in the indoor plant growing area; Keep plants clean with a warm shower.

It is not always possible to completely destroy triops the first time. The fact is that after the measures taken, the larvae of this pest can remain outside the plant for a certain period of time, and subsequently can return again. Therefore, it is recommended from the very first day, when a houseplant appears in your home, to begin taking preventive measures, so that later you do not spend a lot of time and effort fighting these pests.

How to act correctly when treating with chemicals?

Chemicals are dangerous in their pure form for humans and animals. It is better to put the purchased product out of the reach of children and animals before use. Before use, it is recommended to study the instructions and dilute the product in the required proportions according to the rules.

Treatment is carried out in a well-ventilated area or outdoors if the thrips attack occurred in warm weather.

It is necessary to protect the respiratory organs with a mask (in extreme cases, use a scarf or gauze), and put gloves on your hands.

If the processing period occurred in the winter, then it is better to process the flowers in the bathroom. After spraying, it is not recommended to take out flower pots immediately; it is better if they stand behind a closed door for several hours.

It is prohibited to use products in the presence of children.

After completing the treatment procedure on indoor flowers (it will not be possible to get rid of thrips the first time, you will need a second one), it is recommended to wash the floors. It is necessary to remove any remaining product from the floor and possible fallen larvae, and also wash your hands with soap.

The treatment procedure must be repeated after 1-2 weeks, but if after the second treatment the pests have not disappeared, then you immediately need to change the product and repeat the entire process of spraying with poison in a new way.

Safety precautions when processing plants

The use of chemicals requires compliance with safety measures to avoid harm to the human body. That's why:

• In summer, it is better to process the plant outside, and in winter in the bathroom.
• To protect the respiratory system, you must use a gauze bandage or scarf.
• In the case of processing in the bathroom, it is better to place the flower with a pot on the bottom of the bath, after which all the leaves are carefully processed. After this, the flower should be left in a closed bath for some time. After processing, it is not recommended to immediately transfer the flower to its place.
• After the flower is removed from the bathroom, it must be ventilated and then washed thoroughly.
• After a week, it is better to repeat this process for greater effectiveness.

Prevention measures

To protect your plants from thrips in advance, you need to prepare. Having brought home a new flower, you should put it in a separate room, where it should stand for 2-3 weeks.

His condition must be monitored.

Every day you need to inspect the plant and pay attention to the above-described signs of the presence of insects. The temperature and humidity in the room should be optimal. It is necessary to place sticky traps around the room. The plant should always be clean; to do this, place it under a warm shower. It is not always possible to destroy thrips the first time: the larvae can fall out of the plant, but later they will return if they are not found and thrown out.

Immediately after the appearance of a new plant in the house, preventive measures should be taken so as not to spend a lot of effort fighting thrips.

Prevention

In order not to have to use chemicals and traditional methods of getting rid of thrips on plants, it is recommended to follow simple rules of prevention. They will not be able to accurately prevent the possible appearance of pests in the house, but they can reduce the likelihood of their reappearance and further reproduction:

1. New plants are placed in an isolated room for several weeks to monitor how they develop and whether they are infested with larvae. If they appear, since the flower is in quarantine, the spread of thrips to other plants is impossible.
2. Plants must be kept clean. Use a warm shower once every 2 months. If there is heavy dust, wipe the leaves from dust.
3. Monitor the room temperature and maintain moderate humidity in the rooms. Thrips prefer high temperatures and dry rooms.
4. Ventilate the room at least 2 times a week. Some flowers do not respond well to drafts and temperature changes; it is better to remove such pots from a ventilated room.
5. Inspect the plant for possible pests. The more often a visual examination is performed, the greater the chance of identifying an infection at an early stage.

When using remedies for thrips on indoor plants, you must remember that they cannot always help get rid of pests the first time. Sometimes it happens that the larvae do not fall into the zone of action of the poison, and then they can appear in the house again after a while.

3Folk remedies for thrips

If you are a supporter of traditional methods, then be sure to use our advice. They are no less effective against chemicals, but treatment of a houseplant may take longer.

• 150 g of dried medicinal chamomile flowers pour 200 ml. boiling water, leave for 24 hours, spray the plant with it once a day;
• pour turpentine into a deep container, place a flower in a pot in it, leave for 3 hours;
• Wash the leaves and stem in the shower with laundry soap;
• Grind the dandelions along with the leaves, add hot water, leave until the water reaches room temperature, spray the affected flower daily;
• Grate the onion on a fine grater, add 200 ml. warm water, leave for 3 hours and treat the houseplant.

Do not forget about prevention methods, keep the flowers clean, spray them regularly. Monitor the temperature and humidity level of the room where the plants are located.

Common mistakes made when fighting thrips

The most common mistakes made by inexperienced gardeners are when they try to remove thrips from houseplants in a way that is not required by the rules; this happens due to inexperience:

• processing is carried out once;
• during the daytime, flowers are treated with chemicals, which leads to burns;
• surface spraying of plants.

All these mistakes lead to ineffective removal of pests, and the period of combating them increases and becomes more complicated due to lost time.

Even if you follow all the rules and regulations for keeping house plants, there is no guarantee that thrips will not appear in the house. Therefore, the vigilance of the grower is the main weapon in the fight against them. Timely identified pests will not have time to cause severe harm to the plant, and they can be easily dealt with using traditional methods without the use of chemicals.

Reviews and advice from experienced flower growers

The most effective remedy that can cope with thrips is Actellik or Aktara. By following all the standards for treating plants and the room where they are located, you can get rid of pests from the first use.

You can get rid of thrips on indoor plants either by spraying or by immersing the plants in the prepared solution. This method is suitable for small potted plants.

The main thing is to remove all buds and flowers from diseased flowers. Otherwise, after a few days, a new generation of thrips may hatch from the eggs laid in them, and the treatment will have to be repeated.

Violet flowers do not particularly like moisture, so it is often not possible to spray them. Sticky traps and fly strips help control flying pests.
