How to Get Rid of Aphids and Identify Small Black Dots on Cannabis PlantsUpdated 2 months ago

Aphids can quickly infest cannabis plants, causing damage by feeding on sap and weakening growth. If you’ve also noticed small black dots, these could be aphid droppings (honeydew), fungal spores, or insect eggs.

How to Eliminate Aphids

1. Neem Oil Spray – A natural pesticide that disrupts aphid reproduction.
2. Insecticidal Soap – Safe for plants, this washes away aphids and prevents further infestation.
3. Ladybugs & Predatory Insects – Releasing beneficial insects helps control aphid populations naturally.
4. Strong Water Spray – Blasting leaves with water can knock aphids off and reduce their numbers.
5. Diatomaceous Earth – Sprinkling food-grade DE on leaves and soil creates a barrier against pests.

Addressing Small Black Dots

• Aphid Waste (Honeydew & Mold): Wipe leaves clean and improve air circulation.
• Fungal Infections: Treat with a mild fungicide or organic treatment like diluted hydrogen peroxide.
• Eggs or Other Pests: Inspect closely and remove any visible eggs or insects manually.

Regular monitoring and preventive care will keep your cannabis plants healthy and free from aphids and other pests!
