How can I identify a houseplant bug for proper identification and treatment?

To identify a houseplant bug, carefully inspect the plant for any visible pests such as aphids, spider mites, or mealybugs. Use a magnifying glass if needed. Look for signs of damage like yellowing leaves or sticky residue. Once identified, research the specific bug to determine the best treatment method, which may include using insecticidal soap or neem oil.
