Spider Mites: How to Spot, Stop, and Prevent These Tiny Terrors

Signs You Have Spider Mites

One day, your plants look fine. The next, the leaves are speckled with tiny pale dots. That’s how fast spider mites work.

Hold a leaf up to the sunlight. See a faint webbing near the veins? That’s a red flag. Check the undersides—you might spot what looks like moving dust. Those aren’t specks of dirt; they’re feeding mites.

Left unchecked, spider mites can defoliate a plant in days.

What Causes Spider Mites?

Hot, dry conditions give mites the perfect breeding ground. If you’ve been watering less and the air feels parched, they’ll move in fast.

They also hitch rides on new plants, clothes, and even the breeze. Once they land, they multiply like wildfire.

How to Get Rid of Spider Mites

Blast Them Off

A strong jet of water knocks mites loose. Spray every leaf, especially underneath. Do this every few days to keep young mites from settling in.

Introduce Predators

Ladybugs and lacewings feast on mites. But the real killer? Phytoseiulus persimilis, a predatory mite that hunts them down.

Use Neem Oil or Insecticidal Soap

Neem oil disrupts their life cycle. Insecticidal soap suffocates them. Coat the leaves but avoid applying in full sun to prevent burning.

Try Rubbing Alcohol

Mix one part alcohol with three parts water. Wipe down affected leaves or spray lightly. This dehydrates the mites on contact.

Prevent Spider Mites from Coming Back

  • Increase humidity—Mites hate moisture. Mist plants regularly or set out trays of water.
  • Inspect new plants—Quarantine for a few days before introducing them to your collection.
  • Keep plants healthy—Stressed plants attract pests. Water consistently and fertilize as needed.
  • Prune infected leaves—Dispose of them away from your garden to avoid reinfestation.

The key is persistence. Miss a few mites, and they’ll rebuild. Stay ahead of them, and your plants will thank you.
