Neem oil is a natural, multi-purpose pesticide that’s effective against many common houseplant pests. To use:

Chemical Pest Control Options

When natural methods aren’t enough, you may need to resort to chemical treatments:

2. Pyrethrin-based Sprays

Derived from chrysanthemum flowers, these sprays are effective against many pests:
