Spider mites are eight-legged and closely resemble spiders and ticks. These spider mites are extremely tiny and often target the underside of plants, causing the plants to look yellow.

They generally make the infested leaf appear dull, which in reality is just the mites on the underside. Almost all adult spider mites lay eggs and they begin to eat and thrive on plant cells as soon as they hatch.

The most common type of spider mites is the two-spotted spider mite and the red spider mite. All the adults have eight legs and take three weeks to grow into full adults.

Can spider mites come from the soil?

Many people confuse soil mites with spider mites. Both species are two different kinds and damage your plants in different ways. Different kinds of pests require different methods of pest control.

You are more likely to have spider mites than soil mites, as soil mites can only spread to your plant if you use recycled soil. Soil mites are also harmless to your plants.

When it comes to spider mites, the story is very different.

They often target large plants, as they provide them with a large eating space. They prefer plants that produce more nitrogen, meaning plants with a greater amount of nitrogen and phosphorous are vulnerable to these pests.

They are so small that you might not notice them on your plant at all.

The first sign of having a spider mite infestation is yellow dead leaves with dark brown spots, which eventually kill the leaf as they feed on it. A spider mite might just have come to your garden through your pet or through you if you recently visited the woods or went on a hike.

They are so small that they cannot even be seen, which makes it easier for them to spread. A spider mite can come from anywhere, even you or your pet can bring them into your house or to your garden by coming into contact with plants that are infested with these mites.

By the time you realize that your plant is infested with this pest, they have already damaged a lot of leaves.

Because they are so tiny, you see the damage first and the pest second. Seeing webs is also a sign of an infestation, but generally most people realize they have a spider mite infestation after seeing the damaged leaves.

What plants do spider mites come from?

If you live in a hot and humid climate, there are more chances that you will be infested by these pests. Spider mites however look for large plants with large leaves, plants with excess nitrogen, carbohydrates, and enough plant protein.

You can get a mite infestation just as easily as getting ticks. These species are very similar to spiders and ticks and are much smaller in size.

Their small size is also the reason why they don't get caught easily. There are multiple reasons as to how they spread and how they can reach your garden. Due to their webbing behavior, they often escape from predators easily.

There are several ways through which you can get rid of spider mites in case of infestation. You can choose either organic or chemical methods, whichever is best for you plant.

Chemical methods involve anti-pest soap and various pesticides which can kill these pests. The sprays are also very potent. Giving your plant a good spray two times a day can help get rid of these mites which feed on the leaves.
