Maintaining a vibrant, professional environment is a priority for Business Owners & Executives and HR Professionals. Whether it is a sprawling living wall in a corporate lobby or a collection of potted ferns in a home office, greenery signals health, productivity, and luxury. However, nothing spoils that aesthetic faster than an infestation. Learning how to get rid of bugs on indoor plants is not just about aesthetics; it is about protecting your investment.
Discovering indoor plant pests on your interior or exterior plants can be both disappointing and frustrating, leaving you to wonder how you can save them. The good news is that there are some fantastic, natural options to get rid of these creepy crawlies without harming yourself, your employees, or your plants.
Why Do Plant Pests Target Your Office Greenery?
Just like outdoor plants, flowers and greenery inside your home or office can be prone to unwanted insects. Oftentimes, indoor plants are actually more susceptible than those in an outdoor garden for a multitude of reasons. We often invite pests indoors without even knowing it.
How Do Insects Get Inside?
Leaving a door or window open, purchasing fresh produce or flowers, bringing an outdoor plant inside, or using poor-quality potting soil are all ways we make our plants vulnerable to infestation. In a commercial setting, high foot traffic and HVAC systems can also inadvertently transport hitchhiking plant pests.
Pro Tip: New plants should be quarantined for 14 days before being introduced to your main collection to ensure they aren’t harboring hidden travelers.

Plant Pests and Diseases Identification: What Signs Should You Look For?
To keep your plants healthy and hearty, it helps to know what you should be looking out for. Be sure that your plant has strong stems that have non-wilted, nicely colored leaves with a consistent shape. Successful plant pests and diseases identification starts with a close inspection of the foliage. For a deep dive into specific Arizona-based species, the University of Arizona Cooperative Extension offers a comprehensive guide on diagnosing common indoor greenery issues.
If you notice a plant veering away from its original appearance, it may be time to do some further inspecting. Look for:
- Webbing: Often draped along the underside of leaves or where the leaves and stem attach.
- Sticky Residue: Known as “honeydew,” this is a byproduct of sap-sucking insects.
- Discoloration: Yellow spotting or “stippling” on the leaf surface.
- Deformation: New growth that appears curled or stunted.
Insects tend to lurk in hidden crevices, so be sure to search your plants thoroughly. If the task seems daunting for your office’s extensive plant collection, our Horticultural Service can keep your plants healthy and pest-free.
How to Keep Bugs Off Indoor Plants Naturally
There are many natural remedies for removing unwanted bugs from your plants, and they vary based on the type of species you’re dealing with. Below is a breakdown of the most common indoor plant pests and the professional-grade natural strategies to eliminate them.
1. Fungus Gnats
These look similar to fruit flies floating around a plant. You’ll be able to find easily identifiable, yet tiny white or black bugs on top of and in the plant soil.
Our warehouse team prefers to utilize Gnatrol and diatomaceous earth – both natural repellent products – to remedy this problem. It might be helpful to know that gnats are especially prevalent in the spring and summertime, and a good way to determine where they are most bountiful is to place sticky traps in various places throughout your home or yard. In Arizona, we typically see Gnats flying inside shortly after rainfall.
2. Mealybugs
Mealybugs can range in appearance from a light dusting of powder to a heavy coating of cotton on plant leaves. They are notorious plant pests that thrive in warm, moist environments.
Depending on the severity of the problem, we recommend beginning with a homemade solution:
- Mix two-parts water with one-part rubbing alcohol in a spray bottle.
- Add one drop of Dawn dish soap.
- Shake well and spray the entire plant once or twice a week.
In the most severe cases, you may consider dissolving a drop of Dawn dish soap in a spray bottle of rubbing alcohol without water. If this effort doesn’t suffice, you may wish to try Brand X Foliage Cleaner, which is naturally derived and commonly used by interior landscape companies like Plant Solutions.
3. Spider Mites
These creatures are a bit more challenging to identify when their infestation is in its beginning stages. They are microscopic arachnids that pierce plant cells to feed.
A great trick to identify them is to mix water and rubbing alcohol in a spray bottle, then mist the entire plant in a well-lit (but indirect sunlit) area. This method will reveal any webbing that would indicate the presence of spider mites. Treat these problematic plant pests with the same water and alcohol solution as stated above, and be sure to take the time to wipe each leaf down individually for maximum termination.
4. Scale
Identifying these small insects is fairly easy, as they leave behind little brown droppings that stick to foliage. Scale are hard-bodied and can be a little complicated to treat.
- Larval Stage: Insecticidal soap is a plant-safe option.
- Adult Stage: Rubbing alcohol applied directly but sparingly to the affected parts using a cotton swab.
- Severe Cases: Wiping the entire plant down with Brand X may be most effective.
The Strategic Importance of Professional Plant Care
For Office Managers and HR Professionals, the health of office plants correlates directly with employee well-being. According to research from Texas A&M University, plants in the workplace can increase productivity by up to 15%. However, a plant crawling with indoor plant pests has the opposite effect.
Can Insects Be Prevented?
It’s easier to rid plants of unwanted insects when there are fewer present, versus treating an entire infestation. It’s a good idea to get in the habit of proactively inspecting plants on a weekly basis to combat bugs before they become a problem – a quick scan may be all you need!
If you’re a Plant Solutions business or residential customer, we’ll take the guesswork out of maintaining your plants and keeping them pest and insect-free! Our skilled and knowledgeable warehouse team carefully cares for and manages an extensive plant inventory, implementing a program that begins with pest prevention and carries through with our regular maintenance practices.
Understanding the Lifecycle of Plant Pests
To truly master how to keep bugs off indoor plants, one must understand the biology of the enemy. Most plant pests have rapid reproductive cycles. A single female aphid or mite can produce hundreds of offspring in a matter of weeks. This is why “one-and-done” treatments rarely work.
The Role of Humidity and Airflow
Indoor environments often suffer from stagnant air and low humidity (especially in Arizona). This creates a vacuum where indoor plant pests like spider mites thrive. Increasing airflow and using a humidifier can actually act as a mechanical deterrent for many insects.
Soil Health and Pest Resistance
Plants are like humans; when they are stressed or malnourished, their “immune system” weakens. High-quality potting soil and proper fertilization ensure the plant can produce natural chemical defenses against plant pests. Over-watering is the leading cause of fungus gnat outbreaks, as the larvae feed on the organic matter in soggy soil.
Advanced Management for Commercial Spaces
Large-scale green walls and atrium installations require a different level of plant pests and diseases identification. When you have thousands of leaves to monitor, manual inspection is impossible for a busy Business Owner.
This is where Plant Solutions excels. Our horticultural experts utilize Integrated Pest Management (IPM), a sustainable approach that combines biological, cultural, and physical tools to minimize health and environmental risks.
