Is this whatyou're seeing?

Houseplant pests are tiny and hide under leaves, in new growth and in the soil, so most people notice the damage before they notice the bugs.

Not seeing any of these? That's the best time to start.

Most pests start as eggs and tiny nymphs you can't see, and mildew starts as spores you can't see either. By the time you notice webbing, fluff or streaks, they've already spread. Spraying on a schedule is always easier than a rescue.

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!

Your favorite plants are their favorite too.

The plants everyone wants are the ones pests love most. Big tender leaves, tight new growth and leaf joints give them plenty of places to hide.

Monstera

Monstera

Usually bugged by

  • Thrips
  • Spider mites
  • Mealybugs

Silvery patches and scarred new leaves are classic thrips. Check the backs of leaves.

Protect my Monstera
Alocasia

Alocasia

Usually bugged by

  • Spider mites
  • Thrips
  • Mealybugs

Known as a spider mite magnet, especially in dry winter air. Look for fine webbing and speckled leaves.

Protect my Alocasia
Orchids

Orchids

Usually bugged by

  • Mealybugs
  • Scale
  • Aphids

Mealybugs and scale hide at leaf bases and along flower spikes. Spray the leaves and spikes, and don't let water sit in the crown.

Protect my orchids
Fiddle leaf fig

Fiddle leaf fig

Usually bugged by

  • Spider mites
  • Scale
  • Mealybugs

Big leaves mean big hiding spots. Brown bumps on stems or sticky leaves usually point to scale.

Where pests hide on a succulent
Succulents and cacti

Works on succulents and cacti too.

Plump leaves and tight rosettes make perfect hiding spots. Pests tuck in where you can't see them, and the dry, sunny spots succulents love are exactly what spider mites love too.

  1. 1
    Deep in the rosette

    White, cottony mealybugs tuck into the center where new leaves form.

  2. 2
    Leaf joints and undersides

    Mealybugs and scale cling where leaves meet the stem.

  3. 3
    New flower stalks

    Aphids crowd onto fresh bloom stalks and buds.

  4. 4
    Sunny, dry leaves

    Spider mites leave pale speckles and fine webbing.

  • Echeveria
  • Jade
  • Aloe
  • Haworthia
  • String of pearls
  • Christmas cactus

Succulent tip: spray, then tip the pot so no water sits in the rosette.

How Lost Coast Plant Therapy works.

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

Just shake, mix and spray.

1 ozof concentrate makes 1 gallon of spray
  • Fresh peppermint, not chemicalsIt smells like fresh peppermint, so you can spray in the living room without a harsh chemical smell.
  • Covers the whole plantCoats pests and eggs on leaf undersides, stems and new growth, wherever it lands.
  • Leaves no harmful residueBiodegradable, and fine on kitchen herbs up to the day you pick them when used as directed.

Early action matters.

It starts with one plant.Then it's the whole shelf.

Indoors, plants sit close together and pests move easily from leaf to leaf. Catch it on one plant and you protect all the others.

  1. One new plant

    A new plant or cutting comes home with a few hidden hitchhikers.

  2. Hiding in plain sight

    They feed under leaves and in new growth, the places you don't look.

  3. Moving next door

    Mites, thrips and whiteflies spread to the plants touching it.

  4. The whole shelf

    Sticky leaves, webbing and yellowing show up across your collection.

Why indoor pests take over

Indoors, pests have it easy.Your plants need backup.

No rain to knock them off. No ladybugs or birds to eat them. Warm rooms all year, and dry air from the heater in winter, which spider mites love.

Coverage reaches the pests there today. Repeat sprays reach what hatches next.

What houseplant pests cost you

  • A Monstera you've raised for years, scarred with silver streaks
  • Sticky leaves, and sticky floors under the pot
  • Gnats flying around your desk and kitchen
  • Webbing across the Alocasia you just repotted
  • One new plant spreading pests to the whole shelf
  • Tossing a plant you loved because nothing worked

I have used Lost Coast Plant Therapy for years now. I’ve had spider mites and aphids, got rid of the adults as well as the eggs. I use it as a preventative and my crop is squeaky clean. Works great on powdery mildew too.

We love plant therapy. It works great for so many reasons. Smells amazing too. It’s like aroma therapy. Employees fight over who gets to foliar spray it because of the relaxing effect it has when used.

Houseplantquestions.

Yes! It's made with natural and organic ingredients and smells like fresh peppermint, so there's no harsh chemical smell hanging around your home, and there's no waiting period to re-enter the room.

Yes, it's made with natural and organic ingredients and can be used in homes with kids and pets when used as directed.

On contact, it controls thrips, spider mites, russet mites, mealybugs, aphids and whiteflies, along with their larvae and eggs. It also controls adult fungus gnats and helps control scale insects, which are easiest to reach while young. Plus it controls powdery mildew, mold and botrytis on leaf surfaces.

The label rate is 1 oz of concentrate per gallon of water. Shake the concentrate before measuring, and shake the sprayer as you go.

For thrips, spider mites and whiteflies, spray daily for 3 to 5 days, then as needed. For aphids, spray daily for about a week, then as needed. Each time, cover the tops and undersides of the leaves, the stems and the new growth until they glisten.

It controls adult fungus gnats on contact. Spray the soil surface, the pot edges and the lower stems, and you can also use it as a soil drench at the same rate. Gnat larvae live in wet soil, so let the top of the soil dry out between waterings too.

Always test on one plant first, as the label says, especially on delicate or thin leaves. Spray under low light, never above 80°F, and let the leaves dry before bright light returns.

It's a smart habit! Many houseplant pests come home on new plants. Check under the leaves, keep the new plant apart for a couple of weeks, and give it a full spray before it moves next to the rest of your collection.

No spray can repair leaves that were already damaged, so old spots and streaks will stay. Judge progress by the new growth. When new leaves come in clean and you find fewer pests, you're on track.

Every size is the same concentrate. The 4 oz makes 4 gallons, about 16 refills of a 32 oz spray bottle, which is plenty for a few plants. The 12 oz is our most popular size and makes about 48 refills, plenty for a plant shelf or a few rooms. The 32 oz makes about 128 refills and is the better value for a home full of plants.

Your plants can looklike this again.
