How To Prevent Spider Mites

Spider mites seem like tiny white spiders that make webs on houseplants, and they are incredibly destructive pests. It may be difficult, but do not worry, you will get rid of spider mites on indoor plants and eliminate them for taking goods. Here in this article, I will tell you how to prevent spider mites.

Damage to The Plant:

Most of the symptoms could be confused with drought. Here is the resulting damage which spider mites cause to the plant.

  • They use piercing-sucking mouthparts to feed the underside of leaves and needles.
  • As a result, injury produces tiny white, yellow spots or stippling on leaves and needles. 
  • The plant looks bronzed and includes a yellowed discoloration.
  • Webbing indicates a spider mite infestation.
  • They also damage the leaves and flowers of the azalea plant.
  • In a vegetable garden and bedding plants, severe infestations may cause plants to die.

Steps to Prevent Spider Mites:

Here are the following steps which you have to follow to prevent the attack of spider mites.

Monitoring of Spider Mites:

Being able to prevent the spider mites effectively starts with proper spider mite monitoring. Good mite detection begins with viewing the plant. Mites are tiny and difficult to detect. You will usually notice the following plant damage before you see the mites themselves.

  • tiny red spots on the leaves that move.
  • White, cottony webbing that appears on the underside of the leaves.
  • You will need a hand lens to spot them. To watch mites more closely, shake off some leaves onto a white sheet of paper. Once they disturbed, they will move around rapidly.

If you found any of these symptoms, you have to take measures to prevent the spider mite attack. Make sure mites are present before you treat them. Sometimes the mites are elapsed when you notice the damage; plants will often recover after mites have left.

Natural Control:

Getting rid of spider mites through natural control is typically done in one of two ways.


The first way is to isolate the plant then spray the leaves and stems of the plant with pressure water like from a hose or faucet. Spray soon as much of the plant as possible. The spider mite natural control will need to be repeated several times to be effective.

Quarantine And Inspection of Seedlings:

The two-spotted spider mite usually introduced on infested bedding and house plants. When purchasing new plants, carefully inspect the lower leaf surface for any signs of mite activity. New house plants should be quarantined from other plants until you are sure that no mites are present.

Cultural Control:

Cultural practices can have a significant impact on spider mites. Dusty conditions often result in mite outbreaks. Apply water to pathways and other grimy areas at regular intervals.

Periodic hosing of plants with a forceful jet of water can physically remove and kill many mites further as remove the dust that collects on foliage and interferes with mite predators. Disruption of the webbing also may delay parturition until they produce new webbing. Sometimes slight changes where mite susceptible plants located or how they watered can significantly influence their susceptibility to spider mites damage.

Water stressed trees and plants are less tolerant of spider mite damage. Make sure to supply adequate irrigation. Midseason washing of trees and vines with water to get rid of dust may help prevent late-season severe mite infestations. If it requires more control to use insecticidal soap or oil in your spray, but test the product on one to two plants to take care, it is not damaging to them.

Biological Control:

The next to natural control is to introduce natural predators to the infected plant. Ladybugs and other parasitic mites that will kill spider mites are purchased from reputable nurseries. Confirm that the insect you will be able to eliminate spider mites and appropriate for the plant and season you may be using.

Specific Predator:

Spider mites have many natural enemies that limit their numbers in landscapes and gardens, primarily when undisturbed by pesticide spray. Some foremost important predatory mites include the western predatory mite Galendromus occidentalis and phytoseiulus mite species. Predatory mites are about the identical size as plant-feeding mites but have longer legs and are more active than spider mites. They are more teardrop-shaped than spider mites.

Other Predators:

Various other insects are also essential predators, like six spotted thrips named as scolothrips sexmaculatus. The larvae and adults of six spotted thrips also act as a destroyer to lady beetle and the larvae of various general predators like minute pirate bugs, big-eyed bugs, and lacewing larvae. 

Western flower thrips, also named as Frankliniella occidentalis is a vital predator on spider mites eggs and larvae, but this species will inflict severe damage to plants if mites are not present on which to feed.

Establishment of Predator:

The purchase and release of predatory mites are often useful in establishing populations in extensive plantings or orchards—still, the most straightforward results achieved by creating favorable conditions for present predators.

Avoiding dusty conditions and insecticide sprays is the basic tactic.

The primary predator mites commercially available for release are the western predatory mite and phytoseiulus. The western predatory mite is more practical under hot, dry conditions. 

These predators do not take advantage of foliage or become pests; thus, if pest mites are not available when predatory mites are released, the predators starve or migrate elsewhere.

Establishment Of The Predator in The Heavily Infested Area:

If you want to determine predators in an exceedingly heavily infested orchard or garden with few predators, use a soap spray or selective miticide to bring pest mites to a lower level than release predatory mites.

A general rule applied that one predator is required for each ten spider mites to provide adequate control over one application of predatory mites required if you would like to cut back pest populations rapidly. Concentrate the release of the predator in hot spots where mite numbers are highest. Once established on perennials, predatory mites may reproduce and supply biological control indefinitely without further augmentation it applies unless nonselective insecticides that kill the predators.

Chemical Control:

Getting rid of spider mites using chemical control also has two ways.

Organic Pesticides:

For effective treatment in mites, it is important to use selective materials, preferably insecticidal soap or insecticidal oil. Both petroleum-based horticultural oils and plant-based oils like neem, canola, or cottonseed oils are acceptable. There are a variety of plant extracts formulated as acaricides that exert an effort on spider mites.

These include garlic extract, clove oil, mint oils, rosemary oil, cinnamon oil, and others. Do not use soaps or oils on water-stressed plants or when temperatures exceed 90oF. These materials may injure some plants, so check labels and test them out on some of the foliage several days before applying for coverage, especially on the undersides of leaves. It is important to keep repeat applications as; usually, it required.

Point to Remember:

Sulfur sprays may be used on some vegetables, fruit trees, and ornamentals. However, this product will burn cucurbits and other plants sometimes. Do not use sulfur unless it is shown to be safe for that plant in your locality. Use liquid products like sulfur and potash soap combinations instead of sulfur dust, which drift easily and may breathe in.

Do not use sulfur if temperatures exceed 90o F, and do not apply sulfur within 30 days of an oil spray. Sulfur could be an irritant to skin, eye and may also cause respiratory hazard so always wear appropriate protective clothing.


Conventional insecticides usually kill spider mites, so make sure to test the pesticide label to determine if the designation miticide is present. Pesticide claiming for mite suppression is often weak miticides and cannot perform well or may require repeated applications.

At present, there are not any true Miticides registered for over the counter, so most growers use insecticidal or miticidal soaps and oils. Miticides that do not have restricted use only may be purchased by the homeowner but only from a professional supplier.

If you are using chemical controls, remember that they will kill all insects, not just the spider mites. Ensure that the chemical should interact with spider mites to kill them, and the plant is thoroughly covered with the chemical to be effective.

Spider mites treatment frequently becomes a controversy after applying insecticides. Such outbreaks are frequent because of predator killing off and natural enemies, but also occur when certain pesticides stimulate mite reproduction. For example, spider mites exposed to carbaryl within the laboratory are shown to breed faster than untreated populations.

Carbaryl, some organophosphates, and a few pyrethroids also favor spider mites by increasing the amount of nitrogen in leaves. Insecticides applied during weather conditions usually appear to own the best effect, causing dramatic mite outbreaks within some days. So it is preferred to control them by all-natural and organic insecticide because they do not have any damaging impact.

By all the above means, you can prevent the spider mite from attacking and also prevent them from damaging plants if they attack the plant. Click to read more Spider mite related articles on
