What is one method for controlling insect infestations of interior plants?

Applying rubbing alcohol with a cotton swab is a recognized method for controlling insect infestations on interior plants. This approach is effective because rubbing alcohol, or isopropyl alcohol, has properties that can kill certain pests on contact. When applied carefully with a cotton swab, it can target small infestations like aphids, spider mites, or mealybugs without causing extensive damage to the plant itself.

This method allows for precision in application, targeting only the areas where insects are present while minimizing exposure to the plant's foliage. The alcohol works by dissolving the outer protective layer of the insects, leading to dehydration and ultimately death. Additionally, since this technique does not involve harsh chemicals, it is a safe alternative for indoor environments where pets or children may be present.

Other methods to manage infestations, such as the options mentioned, may not provide the same immediate and focused relief from pest issues. Watering plants with hot water can harm the plant rather than help it, planting new seeds does not address existing infestations, and providing direct sunlight can stress plants that are already infested. Thus, applying rubbing alcohol with a cotton swab stands out as an effective and safe pest management strategy for interior plants.
