Which practice can help you manage indoor pest populations effectively?

Rinsing affected areas with a mild soap solution is an effective practice for managing indoor pest populations. This method works by physically removing pests from the plants and disrupting their ability to adhere to the foliage. The soap can suffocate soft-bodied insects like aphids, spider mites, and whiteflies, making it a non-toxic option for pest control. Additionally, this practice can help to cleanse the plant surfaces and provide a better environment for the plants to thrive.

The other practices listed do not directly target pest populations. Infrequent watering can lead to stress in plants, making them more susceptible to pest infestations. Using only organic fertilizers might improve plant health but does not address pest management directly. Adding more plants could inadvertently provide more hosts for pests, leading to an increase in pest populations rather than controlling them.
