Is this whatyou're seeing?

Spider mites are smaller than a grain of salt, so most people spot the damage long before they spot the mites.

It started with a 12 oz that saved my outdoor garden from mites, then it went on to demolish mites and powdery mildew indoors. I am NOT sponsored by them. Natural and safe up to harvest.

I sprayed all my plants last night. They were all looking happy this morning with zero signs of stress, plus it has a very therapeutic peppermint smell! Bugs do not feed on plant material with the solution on it. This is a winner and worth every penny!

How Lost Coast Plant Therapy works.

Lost Coast Plant Therapy is a 3 in 1 concentrate made with natural and organic ingredients. It coats spider mites and their eggs on contact so they can't breathe. Because it works physically instead of as a poison, mites can't build resistance to it.

Just shake, mix and spray.

1 ozof concentrate makes 1 gallon of spray
  • Coats mites and eggsThe spray coats mites, eggs and webbing wherever it lands.
  • Nothing to adapt toIt works physically, not chemically, so it keeps working spray after spray.
  • Leaves no harmful residueBiodegradable and usable up to the day of harvest when used as directed.

Why early action matters

No webs yet?Now is the time to act.

Spider mites multiply fast in warm, dry weather. By the time you see obvious webbing, the colony is already established.

  1. Early stippling

    A few pale dots appear while the mites stay hidden under the leaves.

  2. Colonies build

    Eggs, larvae, nymphs and adults start overlapping on the same plant.

  3. Webbing appears

    Fine silk shows up across leaves and stems as numbers climb.

  4. Plant decline

    Leaves bronze, dry out and drop early, and the plant loses growing power.

Why one spray isn't enough

Spider mites have a life cycle.Your plan needs one too.

Eggs, larvae, nymphs and egg-laying adults can all be on the same plant at the same time. One female can lay around 100 eggs, and in hot, dry weather the whole cycle can take 10 days or less.

Coverage reaches what's there today. Daily repeat sprays reach what hatches next.

Spider mitequestions.

Yes. Lost Coast Plant Therapy controls spider mites and their eggs on contact. That matters because most of a colony is eggs and young mites you can't see yet. Spray the undersides of every leaf, the stems and any webbing, and repeat daily for 3 to 5 days so you keep up with anything that hatches.

Usually for three reasons. Eggs survive a spray that misses them and hatch a few days later. Mites hide on leaf undersides and under webbing, where quick sprays don't reach. And spider mites build resistance to chemical miticides fast. Daily sprays with full coverage, using a product that works physically, deal with all three.

Spray daily for 3 to 5 days, then as needed. Each time, soak the whole plant until the leaves glisten, especially leaf undersides, stems and any webbing. For heavy pressure, the label allows a boosted mix of 2 oz per gallon instead of the standard 1 oz.

No. Lost Coast Plant Therapy coats mites so they can't breathe, instead of poisoning them. There's no chemical for mites to adapt to, which is why it keeps working spray after spray, even on mites that shrug off chemical miticides.

Mites the spray reaches are coated on contact. For stubborn infestations, results are typically visible after repeat applications over 3 to 5 days. Check with the tap test. Hold white paper under a leaf, tap it, and look for specks that move. Fewer movers and no new webbing means you're on track.

Yes. Lost Coast Plant Therapy may be used up to the day of harvest when used as directed. It is made with natural and organic ingredients, approved for use by California Certified Organic Farmers (CCOF), and approved for Demeter Biodynamic certified farms. As with anything you spray, read and follow the label.

Yes, Lost Coast Plant Therapy is safe for bees, ladybugs or praying mantises when used as directed. It works only on contact with soft bodied pests and their eggs. It is biodegradable and breaks down naturally, so it fits into a garden that relies on pollinators.

Yes. Along with spider mites, it controls russet mites, aphids, thrips, whiteflies and mealybugs, plus powdery mildew, mold and botrytis, all on contact. For russet mites, use the boosted mix of 2 oz per gallon and spray daily for about a week, then as needed.

Yes. Indoors, spray under low light and let plants dry before strong light returns. Take plants to a sink or shower if that's easier, and soak the undersides of every leaf. It smells like fresh peppermint, so it's easy to use inside the house.

Every size is the same concentrate, and 1 oz makes 1 gallon of spray. The 12 oz makes 12 gallons and suits most home gardens and houseplant collections. The 32 oz makes 32 gallons for big gardens and greenhouses at a lower cost per gallon, and it is our most popular size. The 1 gallon makes 128 gallons for market gardens and backpack or tank sprayers.
