4. Use Neem Oils

Neem oil is another effective solution to deal with a lot of harmful insects and soil fungus, which always eat our plants’ leaves and roots. It is one of the best organic choices, according to many gardeners. 

Neem oils contain a toxic (Azadirachtin) component, which acts as a mind disturber for spider mites and other insects. Due to this, most insects forget to eat and do not remember the multiplication activities. It also prevents their eggs from reaching up to the hatching stage, and their colonies die out.

But unfortunately, many of us don’t know how to use it correctly. Due to a lack of information, we don’t get the perfect result. 

For the best possible result, we should use neem oils before our plants and soil get affected. You should use them as a preventive measure at least twice a month. 

Make sure you use agriculture base neem oil as they are more organic than medically preferred neem oil.

Before using neem oils, water the plants and soil properly, make agriculture base water soluble neem oil. For that, create a mixture by adding 1 liter of tepid water, 1/2 tsp of use agriculture base neem oil, and 1 tsp of insecticidal soap. 

Make sure you don’t create an unbalanced proportion to prevent hurting plants and soil. Spray the solution evenly to the affected soil areas and the plant’s leaves.

When should you spray this water-soluble oil?

Many people use it when the sun has already risen, and the temperature is also high. But it is actually the wrong method. Oil also gets warm along with the increasing temperature. And, when we use neem oil during his condition, it starts damaging our plants and soil. 

So the late evening or early morning is the right time to use neem oil. It will help the soil and plant to have enough time to absorb it without any harmful effects.

The Prevention of Spider Mites

Everybody knows the proverb,

“prevention is better than cure.”

Your priority should be on preventing your home plants and plant-soil from the attack of spider mites. 

Whenever you bring a new plant to your garden, do a white paper test. It will help you to know the presence of spider mites. Plants that are attacked by spider mites will kill them gradually and make soil unproductive. That’s why you should avoid purchasing plants that have spider mites. 

Additionally, try to keep your plants and soil healthy. Healthy soil will ensure better functionality for plants and help plants to grow fast.  

To ensure healthy soil, you need to water the soil routinely but not overly. Your plant soil needs to hold a standard amount of water. As spider mites love to crawl over dry, warm places, soil with a high moisture level will prevent their growth.

What are Spider Mites?    

Spider mites are the cousin of scorpions and ticks, and they are not insects but particular arachnids. They mainly use indoor plants and pot soil for their accommodation and sources of food. But they live in outside plants and dirt too.

These tiny bugs are as minor as one piece of grain sugar. They have an egg-shaped body structure and eight legs. Though most of them are white, some also show up as black, red, or tan color.

Spider mites are so tiny that you can’t identify them without using a magnifying glass or microscope. You can realize their presence when you see webbing on plants initially. These tiny creatures are mostly seen crawling around your houseplants and nearby soil.

These whiteflies love to live in warm and dry environments. That’s you will find their indoor plants and pot soil during the winter season.

One thing you should not misunderstand is that spider mites may not live on your houseplant soil. Instead, it could be fungus gnats, which damage houseplants and seedlings.

There are different types of spider mites available on earth

But the two-spotted spider mite is the most common one, which was initially discovered in Europe.

This mite is an occasional pest and has orange-yellow color on the body with a single dark mark on both sides. These bugs can severely damage some plants during hot, dry weather.

Spider Mite Lifespan

Spider mites merely do any hard for humans, but they are pretty harmful to plant life and soil. These scale insects live around 3-4 weeks on average. 

However, their small lifespan doesn’t prevent them from reproducing mites. When they live in a favorable environment, their sexual reproduction boosts. Their population may reach double within a couple of weeks. 

A tiny spider gets the breeding power within five days or a maximum of 1 week after birth. Adult females can lay hundreds of eggs within a couple of weeks. Then, the eggs start to hatch within three days and finally come out as mites. Their reproductivity reaches doubles or more within a short period.

It is common not to discover them on naked eyes in soil and plants until their population has exploded. They move from one place to another, inside to outside, and plants to plants based on environmental conditions.

Where Do Spider Mites Come From?

It is hard to discover where spider mites come from. So it isn’t unsurprising to see them at any place. As they are difficult to spot, you can never track their presence until they do some damage to your home plant’s soil or the plant leaves.

However, here are some common varieties of places where you can spot spider mites.

  • Purchasing plants from the nursery that have mites
  • Mixing new soil to old unsterilized soil 
  • Shifting plants to the outside environment
  • Moving plants to inside from outside
  • Coming through windows and doors

Damages to Houseplants by Spider Mite

There are many deadly houseplant pests available in the world, and spider mites are a well-known one. They either attack directly in pot soil or the houseplants. They extract food sources and nutrition from the soil and make it unfertile.

These harmful bugs also attack houseplants and damage heavily or even finish their life within a brief time. Initially, they will make the leaves flecked, discolored, and wizened. After a particular time, the ravaged leaves will fall, and finally, the houseplant will die.

These two-spotted spider mites act more unkindly for indoor plants than outdoors. As a result, you need to take quick action to remove them from soil and plants as early as possible.

Other Facts About Spider Mites 

Can spider mites survive in soil?

Spider mites have the appearance of tiny spiders, which mainly eat plants. When the winter season comes, they prefer to rest in the soil. In the summer season, they crawl up in different places and eat throughout the year.

At what temperature do spider mites die?

Spider mites prefer to crawl around warm temperatures, and they have a high tolerance level. It makes it challenging to get over them easily. Whether it is a cold or warm condition, they can cope up with the situation easily. 

There is no specific temperature that kills mites. But when you use a natural or chemical solution, temperature and other things come in unfavorable conditions. They find it hard to exit for days and finally die.

How long do spider mites live in soil?

As they can easily cope up with soil temperature, they live through their life cycle. We have already known most adult spider mites can live four weeks on average.

What types of plants do spider mites like?
