Common Cannabis Pests and Early Signs

Spider mites, aphids, thrips, fungus gnats, and whiteflies top the list of troublemakers. Look for yellow spots, webbing, sticky residue, or tiny bugs under leaves.

From experience, catching them early saves harvests.

I like to inspect my plants daily, look at the under side of a few leaves…prevention is always better then treatment!

Prevention: The Best Natural Defense

Strong plants resist pests better. Keep airflow good, avoid over-watering, and quarantine new clones.

I’ve used sticky traps and regular inspections in my grows—they work wonders.

Diatomaceous earth around soil bases can be a great deterrent.

Companion Planting for Built-In Protection

Plant marigolds, basil, or nasturtiums near cannabis. Marigolds repel nematodes and aphids; basil deters flies and thrips.

In my outdoor setups, companion planting, healthy plants, and a healthy environment have created biodiversity that controls pests easily.

It’s free and boosts garden health!

Beneficial Insects: Nature’s Pest Hunters

Release ladybugs for aphids or predatory mites for spider mites. They devour pests without harming plants.

I’ve introduced ladybugs indoors—they have helped clear infestations.

In 2025, bio-controls like these are becoming more popular, as folks begin to realize the dangers of chemical treatments.

DIY Organic Sprays and Remedies

I am not big on spraying anything on my plants but water. And I have used a strong spray of water to blast bugs off of plants before.

That being said many growers will use oils to clear infestations, and they can be very effective.

Neem oil mixes (dilute with soap) disrupt pest cycles safely. Insecticidal soap or garlic/chili sprays repel soft-bodied bugs.

• Mix 1 tsp neem + dish soap in water; spray as needed…even weekly.
• Test on a limb or two before spraying your entire plant

Some genetics handle pests better—robust indicas or landraces often do.
