Bugged Out in the Desert: Identifying and Eliminating Common NM Cannabis Pests

Growing cannabis at home in New Mexico has its perks—abundant sunshine, low humidity, and long growing seasons. But it also comes with a not-so-welcome crew: pests that are all too happy to snack on your sticky stash. From tiny mites to flying invaders, your plants could be under siege before you even notice the damage. In this guide, we’ll break down the most common cannabis pests found in New Mexico, how to spot them early, and organic-friendly ways to send them packing.

1. The Usual Suspects: Common NM Cannabis Pests

Spider Mites

• What to Look For: Tiny dots on leaves, fine webbing under leaves or between buds, stippling (little yellow or white spots).

• When They Strike: Most active in hot, dry weather—basically peak New Mexico summer.

• The Damage: Suck chlorophyll from leaves, weaken plants, ruin bud aesthetics.

Aphids

• What to Look For: Clusters of soft-bodied green, black, or white bugs on stems and new growth; shiny honeydew residue; ants farming them.

• When They Strike: Late spring through fall, especially when plants are lush and leafy.

• The Damage: Stunt growth, spread viruses, attract sooty mold.

Fungus Gnats

• What to Look For: Tiny black flies buzzing around soil or base of plants; larvae in the topsoil.

• When They Strike: Overwatered containers and high organic matter.

• The Damage: Larvae chew on roots, which leads to nutrient deficiencies and stunted plants.

Whiteflies

• What to Look For: Small white insects that fly up when disturbed; sticky residue on leaves.

• When They Strike: Greenhouse or indoor grows with poor airflow.

• The Damage: Suck sap from plants, weaken overall health, invite mold.

Leafhoppers

• What to Look For: Fast-moving, wedge-shaped bugs; pale dots where they’ve fed; distorted new growth.

• When They Strike: Outdoor grows, especially in late spring and early summer.

• The Damage: Spread viruses and bacteria, sap nutrients.

Caterpillars / Budworms

• What to Look For: Chunks missing from leaves, frass (droppings), or chewed-up buds.

• When They Strike: Late summer, especially in flowering outdoor plants.

• The Damage: Direct bud destruction—these pests can ruin a harvest quickly.

2. Pest-Friendly Conditions to Avoid

• Dry, dusty air – ideal for spider mites.

• Overwatered containers – welcome mat for fungus gnats.

• Poor airflow – gives whiteflies and mold a safe haven.

• Too much nitrogen – encourages lush growth that pests love to hide in.

• Weedy or grassy surroundings – provide pest breeding zones.

3. How to Catch a Pest Before It’s a Problem

Routine Inspection

• Check under leaves with a loupe or magnifying glass.

• Monitor new growth, soil, and bud sites closely.

• Look for discoloration, spots, webbing, or residue.

Sticky Traps

• Yellow traps catch whiteflies and fungus gnats.

• Blue traps are effective for thrips.

• Place around the canopy and soil line to monitor population changes.

Companion Planting

• Grow basil, marigold, or yarrow nearby to deter pests.

• Dill and cilantro attract beneficial predators like ladybugs and lacewings.

4. Natural and Organic Pest Control Solutions

Neem Oil

• Best for: Aphids, spider mites, whiteflies.

• Use as a foliar spray in early morning or evening to avoid leaf burn.

Insecticidal Soap

• Great for soft-bodied pests like aphids and mites.

• Safe on plants when used according to label.

BT (Bacillus thuringiensis)

• Ideal for caterpillars and budworms.

• A naturally occurring bacteria that kills larvae but is safe for humans and pets.

Beneficial Insects

• Ladybugs for aphids.

• Predatory mites for spider mites.

• Lacewings for a broad spectrum of small pests.

• Release in the early evening or under shade cloth for better acclimation.

Diatomaceous Earth (DE)

• Sprinkle around the base of plants to deter crawling insects like fungus gnats and caterpillars.

• Be sure to reapply after watering or rain.

5. When to Go Nuclear (But Still Organic)

If an infestation gets out of control:

• Remove and bag heavily infested leaves or buds.

• Quarantine affected plants if growing indoors.

• Consider a full plant wash with a diluted neem solution or an organic pesticide like Spinosad.

• Use fans to increase airflow and decrease pest habitat.

6. Preventive Measures for Every New Mexico Grower

• Don’t overfeed nitrogen—it invites pests.

• Water only when the topsoil dries out.

• Sterilize tools and pots between grows.

• Install screens or mesh around greenhouse or patio grows.

• Rotate your IPM (integrated pest management) treatments every few weeks to avoid resistance.
