Natural Remedies for Pest Control
1. Neem Oil
Neem oil is a potent natural pesticide derived from the seeds of the neem tree. It disrupts the life cycle of many pests, including aphids and spider mites. Mix one teaspoon of neem oil with one quart of water and a few drops of liquid soap. Spray this solution on affected plants every 7-10 days.

3. Diatomaceous Earth
This natural powder consists of fossilized algae that dehydrates pests. Sprinkle diatomaceous earth on the soil surface and around the base of your plants to control fungus gnats and crawling insects. Reapply after watering or rain.
4. Companion Planting and Repellent Plants
Plant herbs like basil, mint, or marigolds near your houseplants. These plants repel many common pests. Additionally, regularly inspect your plants for early signs of infestation to catch problems before they spread.
