Spider Eggs in Plant Soil - How to Remove Them Quickly

The presence of spider eggs in plant soil indicates that your pot will soon be overrun by these creepy insects. For this reason, you need to discover the quickest method for getting rid of these eggs.

Additionally annoying are spider webs, which are unsightly and might give the impression that your home is not well-kept. Only destroying the soil-based spider eggs has little benefit.

You must also eliminate spiders from your home. To get rid of a spider infestation, you must destroy both the spiders and their eggs.

Thankfully, careful monitoring and the provision of the appropriate kinds of products can be used to control spiders and their eggs. Information on eradicating these pests is provided below.

What Do Spider Eggs Look Like?

Do spiders lay eggs? is a question I receive a lot. Clearly, the answer is a resounding YES.

The sacs of spider eggs are typically tiny, sphere-shaped objects in white or vivid colors that resemble grapes. Usually a silk sac is used to protect these eggs.

The sac is typically no bigger than a quarter.

What Are Spider Eggs in Plant Soil?

Spider eggs in your plant's soil might be from large, full-sized species of spiders or they might be from mites. Despite being tiny pests of houseplants, these mites are also arachnoids and belong in the same class as spiders.

They grow in your soil for a number of reasons, but the main one is that they feel safe and able to develop well there.

You're interested in learning more, right? Take a look at the sections that follow.


Spiders like to bury themselves in the ground and lay their eggs there. What about the appearance of spider eggs? The round, creamy white sacs containing these eggs are wrapped around them.

Some of the sacks can be smooth while others look raggedy depending on the type of spider in question. These sacs are almost all incredibly small and have a jelly-like consistency. It will be difficult for you to locate it.

Depending once again on the type of spider, each sac also holds a different number of eggs. On average, spider eggs per sac range from 150 to even thousands of baby spiders.

Spider Mites

Because they are so tiny, it is difficult to see these mites with the naked eye. If you want to properly identify spider mites, you may need to use a magnifying glass; otherwise, all you will see are tiny dots moving. As a result, their eggs are completely invisible to the naked eye.

Unlike ordinary spiders, a spider mite infestation can be disastrous for your plant. They are unwanted guests who will suck up all the beneficial fluid passing through your plant. The plant's leaves will start to drop and turn yellow as it begins to wilt.

You can identify an attack on your plant and its soil by looking for these symptoms. Look under a leaf you've picked up; you'll find a lot of these spider mites gathered close to the nodes.

Why They Lay Eggs in Houseplant Soil

Spiders and spider mites usually lay their eggs in the soil because they deem it a safe spot for their babies to grow. As it aids in the hatching of their eggs, the soft, warm, and moist surroundings are also ideal for them. In addition, the soil and plant provide their larvae with an abundance of nutrition as they develop into adult insects.

Where Do Spider Mites Come From?

The unfavorable aspect of spiders is that they can appear anywhere.

Keep in mind when purchasing a houseplant that if it has a few spiders or spider eggs in its potting soil, you will quickly develop a spider mite infestation.

Before repotting the plant, it's also essential to clean the pot thoroughly. Growing your plant outdoors in the summer may result in it having some spider mites when you bring it inside. You are aware of what will happen next.

The difficulty is that spider eggs are not readily apparent to the unaided eye. They therefore go unnoticed until their population skyrockets.

How to Remove Spider Eggs from Soil

To remove eggs from spider and spider mites in your soil, you can try drying the soil or using natural or chemical insecticides. Insecticide, peroxide, and vacuum cleaners are other options. But our favorite pest control techniques are still biological ones.

Ahead are all the specifics.

Work towards Drying Your Soil

Because of the moisture in the soil, spiders find it convenient to lay their eggs there. They look for soils that are warm, muggy, and moist, which is typical of most soils. For this reason, the first step in getting rid of them is a good idea: drying the soil.

You must stop watering the plant until the soil becomes thoroughly dried. The eggs will deteriorate and eventually die as a result of this. Dry soil also eliminates pests like millipedes and springtails, which serve as mites' primary food source.

This method might not work for all the plants, though. Succulents can withstand dry conditions fairly well, but plants that prefer moisture, like pothos, cannot go for long periods of time without water. Don't worry; in this situation, you can try one of our other methods.

Spider Eggs in Plant Soil

Neem Oil as a Natural Insecticide

Neem oil is a wonderful ingredient in killing all sorts of plant pests. Whether they are fungus gnats, spider mites, spiders, or other pests, it is effective against all of them. Compared to insecticides that use chemicals, it is also better for the health of the plant.

One tablespoon of neem oil, one teaspoon of liquid soap, and one gallon of water are the proper amounts to mix it in. This mixture only needs to be poured into the soil once per week. Pour at cooler times of the day because hotter oil may cause the plant to burn.

This oil works because it disrupts the life cycle of the eggs in your soil. The eggs won't be able to develop into larvae. It will also eliminate an adult spider and spider mite.

Other Natural Insecticides

Since genuine neem oil cannot be found everywhere and at all times, we also offer you some other options. These are also natural alternatives that don't endanger the wellbeing of the plant.

Cinnamate, which is derived from cinnamon, can be applied frequently to kill spider and spider mite eggs. Furthermore, it ends the life of newly hatched eggs. Apply it every third day for two to three weeks without skipping a day.

All harmful mites are killed by the natural oil of rosemary without harming the good mites. Every week, spray it on the soil after mixing it with water.

Biological Control through Bacteria

To combat the spiders' eggs in your soil, you can use specific bacteria. Bacillus Thuringiensis Israelensis, or BTI for short, is the one to use in this situation. This bacterium kills the larvae once the eggs have hatched.

This type of insect egg control is available from any well-stocked nursery or gardening store. Prior to using this technique, you must thoroughly water the plant as a precaution. Pour the mixture of your BTI and the prescribed amount of water on the problematic soil, then take a seat and watch the bacteria at work.

Biological Control through Pests

You can introduce certain pests to eliminate the tiny white eggs in houseplant soil . In nature, spider mites can be successfully eaten by ladybugs, lacewings, and even other mites.

You can order them online or at your neighborhood farmer's market. Remove anything that would hinder these pests' ability to grow and survive before introducing them to the soil. This includes an excessive amount of mulch, leaves, and flowers.

What feature of this technique is the best? With no significant negative effects, it keeps your plant healthy. Additionally, it works to stop future attacks by spider mites.

Use Insecticidal Soap

This is one of the easiest methods for those who don't want to use harsh chemicals on indoor plants. In one liter of water, combine one teaspoon of insecticidal soap. This will cause a mild insecticidal solution to form.

In addition to spraying the plant, directly pour it on the soil. The eggs of spiders and spider mites will be greatly reduced by its weekly use.

Hydrogen Peroxide

To kill spider mites and spiders, especially their eggs, you can use peroxide, a chemical that is exceptionally potent and widely accessible. Without first dilution, it shouldn't be added to the soil. It's best to use three percent peroxide and add it to one whole spray bottle.

Spider larvae and eggs are killed by the fizz that is created when it reacts with water. They become incapable of surviving due to pH changes in the soil.

Go for Alcohol

You need to kill any potential eggs on the plant structure in addition to eliminating spider eggs in the soil. Rubber alcohol is useful in those circumstances. Simply take a cotton pad, dunk it in any household alcoholic beverage, and rub both sides of the cotton pad on the plant leaves.

Our favorite alcohol to use is 70 percent isopropyl alcohol. It has always done the job successfully.

Use a Vacuum Cleaner

This is one of the most innovative methods by which you can control spider populations within your soil. It works especially well when eggs, larvae, and webs are visible on the soil's surface or inside soil cracks.

Switch on your cleaner while directing it toward the soil's surface. Everything will quickly be sucked up by it. Then, you can dispose of everything as needed.

Keep in mind that this method is, of course, not 100 percent effective. Deep in the soil, eggs and larvae won't be destroyed. You must also employ additional supporting techniques.

Poison for Insects

This method is for spiders and does not work against a spider mite infestation. The majority of this is available as a powder that must be combined with a certain amount of water.

Along with some additional care instructions, this quantity will be noted on the instructions. Just be sure to purchase poison designed to kill spiders.

Chemical Insecticides

Chemical insecticides are undoubtedly the most efficient way to get rid of any pests in the soil, be they spiders, mites, fungus gnats, or anything else. The only concern they pose is that they are not the safest for plants, pets, and humans. We advise choosing an insecticide that can be diluted with water, such as one that is powdered or granular.

In accordance with the manufacturer's instructions, you can then pour this mixture onto the soil. You could also put a little of it in a spray bottle and mist the plant with it. Using it as directed on a regular basis will kill the parent pest, their eggs, and larvae.

Safety Precautions

Naturally, it would be best to keep yourself, your children, and your pets safe when using such harsh chemicals. Here we have compiled some precautions you must follow when using insecticides.

  • Before spraying, relocate the plant to a hidden space.
  • To prevent chemical burns, it is best to water the plant in advance.
  • To avoid unnecessary exposure, put on protective gear like gloves, clothing, and eye protection.
  • Wear a hat because your scalp can absorb chemicals from the air and transport them into your blood.
  • After applying the insecticide, keep kids, animals, and the plant away from each other for at least a few days.

Use Hydraulic Pressure

Again, this is not the most effective and total method of eradicating eggs and spiders from your soil. Utilizing this method intermittently will keep the spider population in check, though, if you are busy and short on time.

Use a jet nozzle to spray your soil vigorously with water. The soil's eggs and larvae will be ejected. Even worse, the pressure could cause harm or even death to some of them.

This is especially useful if you have spider sacs full of eggs over the surface. All it takes is one jet stream to send these sacs flying.

How to Control Spider Mites, Mealybugs, and Fungus Gnats?

  • Make sure to regularly dust the leaves and clean the plants.
  • A strong stream of water will effectively remove a few spider mites.
  • Spiders hate dry soil, so be consistent with your watering and keep the ground wet.
  • To maintain the ideal moisture level for your plant, use a humidifier.
  • To ward off spider mites, you can grow various outdoor plants in your gardens, such as chives or chrysanthemums.
  • For a while, keep new plants separate from the existing ones to avoid problems.


You've just learned everything there is to know about spider eggs in soil and how to get rid of them.

  • By letting the soil dry out, spider egg sacs can be killed.
  • To remove them from the ground, you can use a jet spray or a vacuum.
  • For an immediate response against these eggs, you can also purchase commercial insecticides or insect poison.
  • The most secure method is to introduce BTI bacteria or predatory pests like ladybugs.

You are completely prepared to take on those pesky eggs in your soil now that you have read this guide. To keep your plants healthy, you only need to pay closer attention to consistency rather than any particular method listed in the article.

Frequently Asked Questions About Spider Eggs in Plant Soil

Can I Use Bug Spray to Kill Spider Eggs in Soil?

Many different species of spiders and their eggs are killed by bug spray, but the problem is that both the arachnids and their eggs must come into direct contact with the spray. With spider eggs in plant soil, there is no practical way to do this other than to use a quantity of spray that is likely to pose a health risk to both plants and people.

Can I Use Bleach to Kill the Spider Eggs Found in the Soil?

Again, not really, and for the same reason that bug spray is useless against soil-borne spider eggs. The difficulty lies in the fact that the bleach must come into contact with the spider eggs. You can't stop the bleach from coming into contact with the plant, so you end up with a dead plant.

How Many Eggs Do Spiders Normally Lay?

A reasonable answer for many species is "around a thousand eggs". Because their hatchlings are stronger and more likely to live to adulthood, some hardier spider species only produce ten eggs in each sac.
