Eco-Friendly Pest Management: Natural ways to control houseplant pests

Understanding houseplant pests

Houseplants can bring a touch of nature and vibrancy into your living space, but they can also attract unwanted guests in the form of pests. These tiny invaders can wreak havoc on your beloved plants, causing damage to leaves, stems, and roots. Exploring natural ways to control houseplant pests is the first step in developing an effective and eco-friendly control strategy.

Some of the most common houseplant pests include:

  • Aphids: These sap-sucking insects can quickly multiply and leave behind a sticky residue known as honeydew, leading to sooty mold growth.
