How to Get Rid of Soil Mites — Tricks to Keep These "Friendly" Bugs Under Control

Gardening can be quite a relaxing and therapeutic process for many, but when little creepy crawlies start invading your space, the peaceful process can turn into a rigorous one.

There are a range of different bugs that love to roam around your backyard, some of which are beneficial garden insects for your beloved plants — soil mites being one of those.

They’re tiny, but somewhat mighty. Soil mites are small arthropods often found in soil, leaf litter and organic matter. Plant expert, Tony O’Neill from Simplify Gardening tells us, these little creatures are actually ‘important contributors to the decomposition process in ecosystems and they belong to various families, with most being harmless to plants’.

Although soil mites are not harmful in smaller groups, if their population becomes excessively high, experts says they might start impacting young plant roots or tender organic matter. So, what would be the best way to prevent this from happening? Here is everything you need to know.

How to get rid of soil mites

If you are fed up of these mites squirming their way into your soil, there is an effective way of getting rid of them. Tony says you should follow these 5 steps to eliminate them from your backyard and plant pots.

1. Identify the affected area - Analyze your soil and see where you notice excessive soil mites.

2. Dry out the soil - A little bit goes a long way. Tony says drying out the soil will help keep these insects away as they thrive in moist conditions. So, reduce watering to manage the moisture level.

3. Apply a neem oil solution - Tony suggests you 'mix 2 teaspoons of neem oil with a quart of water and a squirt of mild soap, which helps emulsify the mixture. Apply this directly to the soil, not the plant foliage'. You can also buy readymade sprays, like this neem oil from Walmart.

4. Repeat the previous step - The plant expert says you should 'apply neem oil once a week for at least three weeks to ensure all mites and their larvae are affected'.

5. Monitor the soil - Be sure to do this 'regularly and maintain lower moisture levels to prevent future infestations'.

Last, but not least, Tony tells us to 'increase soil drainage and reduce watering frequency to make the environment less hospitable for mites'.
