Clean And Sanitize The Containers

Once the soil is in its final container, clean and sanitize the pot. If you are using a plastic or metal container to transport your potting soil, wash it thoroughly with warm soapy water. Rinse thoroughly before filling with fresh potting soil. 

For wooden or other porous materials, use a bleach solution to sanitize them after washing them well with soap and warm water (see below). Let dry completely before adding plant material.

Soak The Soil

Soak the soil in a bucket or tub for at least 24 hours before planting. The dryer your potting soil is, the more likely it is to have bugs in it. So you want to make sure that all of those little critters are killed off before you plant anything into your container. 

The easiest way to do this is by soaking your potting soil for an extended period of time (at least 24 hours), so that any bugs that might be hiding within will drown and die.

When it comes time to actually plant, simply drain off any excess water from the top layer of your soil mix until only moist remains—but not soggy! 

You don’t want any excess moisture lingering around once you’ve planted something because it can cause fungus growth on the roots and rot them over time if left unchecked.

Don’t Use Old Soil

If you have been using the same potting soil for a while, it’s time to get rid of it. Old potting soil can harbor insects and fungi that can cause problems for your plants. 

You will also want to keep an eye out for signs of insects or fungus in new bags of potting soil too, but since they aren’t as likely as older bags, there isn’t quite as much concern about this issue in general.

Choose Your Medium Carefully

If you’re going to use soil as your medium, make sure that the soil itself is clean and sterile. This means choosing a brand of potting mix that has been treated with heat, pesticides or natural remedies to kill off any possible pests.

If you don’t have access to a clean and sterile potting medium—or if you just want something different you can also use vermiculite instead of soil as a base for your plants. 

Vermiculite is made from mica ore and expands when it gets wet; this makes it a great option for growing seeds because it’s lightweight enough that they won’t root themselves into dense clumps of clay-like dirt.

Start With A Sterile Mix

To ensure that your soil is bug-free, start with a sterile mix. Sterile potting soil is free of pests and diseases (bugs), weed seeds, rocks and other debris, and organic matter.

You may be wondering why you should use sterile potting soil instead of regular garden dirt. Some people would argue that it’s better to get some fresh leaves in the mix to help enrich it. While this may seem like a good idea at first glance, there are several reasons not to do it:

The leaves themselves can carry diseases or pests that could introduce themselves into your new plant life if you have them around when adding water or fertilizer.

If the leaves were laying around near plants that were fertilized previously—or even just nearby—they could be contaminated with leftover fertilizer that could damage your new plants when added in later on down the line (the same goes for water).

The nutrients from decomposing organic matter can cause root rot in certain types of plants because they may not be able to handle them well; this results in stunted growth and eventual death of said plant(s).

Grow Plants In Their Natural Climate.

In general, you should try to grow plants in their natural climate. This way, the plants will be hardier and more resistant to pests. They’ll also grow faster and healthier since they’re used to a specific climate.

Heat treat the medium

Another way to make sure there are no pests in potting soil is by heat treating the medium. Heat treatment is a good way to kill pests, but it does not affect the soil itself. Heat treatment can be done in either a microwave or oven.

Heat treatments should be done at 120 degrees Fahrenheit for 30 minutes, which will kill any pests you may have brought into your home with your new plants or garden supplies.

Add Insecticides For Prevention

Use a natural insecticide. The best way to prevent pests is to use a pesticide that’s safe for plants, animals and humans. 

Many pesticides can be harmful to people, pets and the environment. If you have children or pets in the home, make sure that your choice of insecticides is safe for them too.

Don’t use an insecticide that causes adverse reactions in humans or pets (like vomiting or diarrhea). If it’s bad enough to make you sick, then why would anyone think it was okay for their plants?

Use Neem Oil Or Other Natural Remedies

If you’re really concerned about the possibility of bugs in your potting soil, you can always try a natural remedy. 

Neem oil is a natural insecticide that works by disrupting the life cycle of insects. It’s available in liquid and powder forms as well as concentrate, so you can choose which one best fits your needs. 

Neem oil can be used on both indoor plants and outdoor plants (just make sure to follow the directions for application carefully). In addition to preventing pests from attacking your plant(s), neem oil may also help repel other bugs like ants and spiders!

If you’ve found yourself with a bug problem after all this hard work, don’t worry—neem oil isn’t just limited to stopping pests—it also has other uses such as repelling mosquitoes or keeping slugs away from crops!

Don’t Crowd Plants

When you’re trying to figure out how to make sure there are no bugs in potting soil, remember that plant roots need room to grow. 

If you try to pack too many plants into one container, they’ll compete for nutrients and space. As a result, your plants may become stressed and die.

On the other hand, if you give each plant enough room to spread its roots—and place them next to other compatible varieties—you’ll prevent any cross-contamination between species (which can also be an issue). For example:

  • Alyssum won’t survive under cherry trees; they’re too shady!
  • Mint likes damp conditions but not warm ones; so it won’t do well with cacti or succulents!


There are a few things you can do to make sure your potting soil is bug free. First, buy it from a reputable source that uses clean processes when manufacturing their product. 

If possible, get some samples and examine them under magnification before deciding on a brand or product. Finally, always wash your hands after handling potting soil to avoid transferring any unwanted hitchhikers!
