### 4. **Diatomaceous Earth (DE)**
Diatomaceous earth is a natural powder made from fossilized remains of diatoms. It works by physically damaging the exoskeleton of aphids, causing them to dehydrate and die. DE is safe for humans, pets, and most beneficial insects, making it an ideal choice for organic gardening.
#### Ingredients:
– Diatomaceous earth (food grade)
#### Instructions:
1. Lightly dust the diatomaceous earth onto the affected plants, especially on the undersides of leaves.
2. Reapply after rain or watering, as moisture can wash it away.
**Tip:** Wear a mask while handling diatomaceous earth to avoid inhaling the fine powder.

### 5. **Rubbing Alcohol Spray**
Rubbing alcohol (isopropyl alcohol) is another effective natural pesticide that works by breaking down the protective outer coating of aphids and other pests. It can kill aphids on contact, making it an instant solution for a heavy infestation.
#### Ingredients:
– 1 part rubbing alcohol (70% isopropyl alcohol)
– 1 part water
#### Instructions:
1. Mix equal parts rubbing alcohol and water in a spray bottle.
2. Shake well to combine.
3. Spray directly onto aphids, making sure to coat them thoroughly.
4. Reapply every few days until the aphids are gone.
**Tip:** Always test the rubbing alcohol solution on a small part of the plant first to ensure it won’t cause any damage, as alcohol can harm sensitive plants if overused.
