What are spider mites?

Spider mites are tiny arachnids that resemble spiders. They are not insects but rather belong to a different group of animals called Arachnida.

Spider mites can cause a sizeable amount of damage to plants and crops and can be difficult to get rid of. They are often introduced into a home or garden through potted plants or flowers.

These tiny pests typically feed on the sap and leaves of plants and can cause significant damage in large numbers. They thrive in hot weather and can cause significant damage to crops and gardens.

While you can control them with pesticides, it is important to catch them early and take preventative measures to stop them from spreading.

One of the most commonly observed types of spider mite is the two-spotted spider mite, which can be identified by the characteristic black spots on its body.

What are the Early Signs of Spider Mites?

Spider mites are a highly common pest that can quickly infest and damage plants. They are extremely tiny and difficult to see with the naked eye, but you can use a magnifying glass to identify them.

If you spot any of the following early signs, it is likely that you have spider mites in your house. In fact, these are the most common early signs of spider mite infestations –

– Yellow or brown spots on leaves

– Webbing between leaves

– Mite droppings (tiny black dots)

If and when you do notice these early signs, it is crucial to take prompt action against these pests before they infest your potted plants!

What do spider mites look like?

Spider mites are small, red, yellow, black, or brown moving dots that can be difficult to see with the naked eye. They often go unnoticed till the point that there is a large infestation.

Typically, until your plants or house is infested with spider mites, your chances of being able to spot them are next to negligible. However, using a magnifying glass to spot these pests can be an easy way to identify their presence on your plants or in your home!

Visible damage caused by spider mites

Spider mites are tiny arachnids that feed on the sap of plants. Here are the top early signs of spider mites in your home and your plants.

Discoloration of leaves

Spider mites are usually difficult to detect with the naked eye, but they can be detected by their webbing and feeding damage. They cause damage to our plants by sucking out the cell contents, which leads to small dots or stippling on plant tissue.

This damage can stunt the growth of plants and even kill them. The leaves could turn into colors like bronze and yellow rather than being green in color.

Severe damage to plants

Spider mites are essentially tiny arachnids that can cause extensive damage to plants before they’re even visible. The first sign of a full-blown infestation is usually damaged leaves, which can be caused by the spider mites sucking sap from the plant.

If you think you might have a spider mite problem, it’s crucial to take action as soon as possible to prevent further damage.

The presence of webbing around the leaves and stems of your potted plants

Another tell-tale sign of the presence of spider mites is any webbing around the leaves and stems of your potted plants. If the webbing is still in its developing stages, it might be challenging to spot.

However, if you can spot elaborate webbing around your plant’s leaves, you are most likely dealing with a spider mite infestation. This webbing can also help you distinguish between other plant pests like fungus gnats or aphids and spider mites.

Life Cycle of a Spider Mite

Spider mites have a life cycle that consists of four stages: egg, larva, nymph, and adult. The larvae eat the host plant for a few days and turn into eight-legged nymphs before turning into an adult. Female spider mites lay eggs on the underside of leaves, and the eggs hatch in two to three days.

Spider mites are an extremely common pest that can cause significant damage to plants. What’s more, they can complete their life cycle in as little as one week, meaning they go from being a tiny egg to a full-grown adult in a very short amount of time.

This makes it extremely necessary to keep an eye out for early signs of spider mites and take action quickly if you see them.

Although spider mite populations tend to grow more slowly during cooler and wetter weather, they do not disappear altogether in colder weather. In fact, even if the weather is too cold or wet, their populations can still grow larger as they struggle to survive.

Spider mites are at their best in hot, dry weather, and their populations can rapidly increase under these conditions. They may have been around your beloved plants all along.

Still, numbers don’t become noticeable until weather conditions become favorable or infested plant material or shoes and clothes of workers blow in with the wind. If you see tiny and yellowish spots on the leaves of your plants, this is an early sign of spider mite damage.

Controlling and Managing Spider Mite Infestations

Spider mites are a common problem in both indoor and outdoor plants. They can be eliminated using different types of pesticides, but some are safe for plants. Biological control is an alternate method that uses predators to take care of the spider mites.

Below, I have highlighted the best principles that you can use to eliminate spider mites entirely from your house and your indoor garden.

Observe the spider mite hotspot

It is important to monitor the target area before you treat it for spider mites. Checking for signs of spider mites and other pests will help you avoid further damage.

You can monitor areas where you’ve already seen spider mites in your house. A good-quality magnifying glass can be a handy tool that you can use to observe the presence of spider mites. 

After you’ve located the hotspot for spider mites, your next step should be to choose an effective mode of treatment. There are three primary ways to treat spider mites: biological control, chemical control, and cultural control.

Biological control uses predator insects or mites to eat the spider mites. Chemical control kills the spider mites with pesticides. Cultural control changes the environment so that the spider mites cannot survive.

Biological mode of control for spider mites


Spider mites can be eliminated with the help of predatory mites. Predators are more effective in the early stages of an infestation and should be used before chemical controls.

Biological control, using predator mites, is often the best solution for eliminating spider mites. Predator mites are available for purchase and can be released into the environment where spider mites are present.

These tiny creatures will feed on the spider mites until they have eradicated them from the area. Once predator mites have established themselves, they may reproduce and provide residual control over spider mite populations.

Chemical mode of control for spider mites

Regular insecticides like carbaryl do not necessarily kill spider mites. In fact, spider mites have been proven to thrive in the presence of the chemical. To utilize chemical modes of control for spider mites, you need to use strong miticides. 

Further, miticides need to be applied in the right kind of weather and environment. Applying it in the sub-optimal environment could lead to simply aggravating the spider mite population and bringing them out in the open.

Cultural mode of control for spider mites

There are a variety of cultural control methods that can be used to help reduce spider mite populations. One of the most vital aspects of taking care of your plants is watering them regularly and deeply. You can also spray your potted plants with water or insecticidal soap.

The reason this works is that spider mites prefer living in arid and dusty environments. If you don’t allow such an environment to exist, your chances of being able to expel spider mites from your plants are pretty high. 

Many people also rely on cultural control methods such as vacuuming or washing the leaves of the plant, but these methods may not always be effective. Insecticidal soaps or oils can also be used to kill spider mites, but it is important to test them first before use in case they harm the plants.

What environments are ideal for the growth of spider mite populations?

Spider mites do their best in hot and dry conditions. They are more likely to be an issue in indoor growing areas that are underwater.

Therefore, typically, the two major reasons that encourage the growth of spider mite infestations in your plants are a lack of proper watering practices that leave the plant dry and using unnecessarily excessive amounts of nutrients for your plants.

Further, spider mites will also thrive in environments with high levels of nitrogen. When there is an abundance of these compounds, the spider mite population will grow exponentially.

In order to prevent spider mites from taking over your garden or house, you must be mindful of the conditions that favor their growth and take steps to mitigate them.

How did my plant get spider mites?

Spider mites are more likely to infest indoor growing areas, as the climate is more hospitable to them. They can be introduced to your garden by bringing in infected plants or through contact with other objects that have spider mites on them.

They could also infest your plant if you’re in the habit of applying too many nutrients to your plants and their leaves!

What does an infestation of spider mites look like?

An infestation of spider mites will typically look like tiny little specs on the leaves of the plant and usually cluster around the stem. An early-stage infestation of spider mites will look like tiny spots on the top of leaves that turn yellow as the spider mites suck out the chlorophyll.

If you see these signs, it is important to take action quickly to prevent an infestation. There are quite a few number things you can do to help prevent spider mites, including, but not limited to, spraying your plants with water regularly, using horticultural oil or insecticidal soap, and removing any infected plants from your garden.
