Houseplant growers often find pests soon after new plants arrive from nurseries and garden centers. Experts say insects can enter homes through soil, stems, and leaves, where small movements or thin webs may appear. Studies from plant centers show that checking plants before buying helps reduce later damage. Inspections should include leaves and roots to find early signs. These actions protect indoor plants and reduce the need for chemical treatments, which experts say are not always necessary.

Prevention starts with careful inspection and repotting to remove old soil and possible eggs. Fresh soil and clean pots reduce hidden insects and lower the risk of disease. Diatomaceous earth works on dry soil because it dries insects that walk across it, but water slowly reduces its effect. Bottom watering and short isolation periods help stop insects from moving between plants. Researchers report that these simple methods support healthy roots and protect plants from future pest problems.
