What pests does it target?

Lost Coast Plant Therapy effectively targets a wide range of soft-bodied pests, including spider mites, aphids, thrips, whiteflies, and more. It also controls mold, mildew, and fungal diseases on contact.

Can it be used during all stages of plant growth?

Yes! Lost Coast Plant Therapy is safe to use during all stages of plant growth, from seedlings to harvest. For flowering and fruiting plants, ensure proper application by saturating leaves and stems while avoiding excessive moisture on blooms or fruit.

Does it leave any harmful residue on plants?

No, it does not leave harmful residue. Lost Coast Plant Therapy is biodegradable and designed to dry quickly, usually within 15 minutes. This ensures your plants remain clean and free from unwanted chemicals.

Can it be used indoors and outdoors?

Absolutely! Lost Coast Plant Therapy works effectively in both indoor and outdoor environments. For indoor use, apply when lights are off and ensure proper ventilation. Outdoors, apply early in the morning or evening when temperatures are below 80°F.

Can it be used on edible plants?

Yes! Lost Coast Plant Therapy is safe for edible plants, including fruits, vegetables, and herbs. Its natural ingredients ensure no harmful residues, even when used right up to the day of harvest.

How long does it take to see results?

You’ll often notice results immediately for soft-bodied pests like aphids and whiteflies, which are suffocated or dehydrated on contact. For mold, mildew, and more stubborn infestations, results are typically visible after repeat applications over 3–5 days.

Amazing company, owned by first-rate folks! I've been using the products here in MI for 2 years, and it is outstanding both indoors and outdoors as a treatment or preventative, right up to the day of harvest. This stuff knocks out aphids extremely quickly and easily. I can treat 20 mature plants in under 30 minutes with a backpack sprayer. The first treatment kills 95% of the aphids, and the second treatment gets all the stragglers that were tucked away and left to wander without a food source.

Your spray is the only product that has proven itself to actually be safe to use on plants at all stages. We have over 200 strains of plants. Several of them do not like anything sprayed on them. We tried pesticides both natural and unnatural and all of them have been a waste of time, money and have caused serious damage to some of our sensitive strains. Lost Coast Plant Therapy works and is a permanent product in our facility!

Lost Coast Plant Therapy is our most-used and go-to product for protection from pests, both for the intake of new plants into the garden and for preventative maintenance for all of our clones throughout the year. It is essential for our customers to start their crops with clean plants free of pests or pathogens. LCPT is our go-to spray for our Vegetative Integrated Pest Management System. Highly recommended! Thank you, Lost Coast!

I sprayed all my plants last night with the lights still on at 50%. They were all looking happy and praying for light this morning with zero signs of stress, plus it has a very therapeutic peppermint smell! Bugs do not feed on plant material with the LCPT solution on it. This is a winner and worth every penny!

Ever seen a gift from heaven? Well its Lost Coast Plant Therapy. It started with a free sample that saved my outdoor from caterpillars and mites to absolutely demolishing mites and Powdery Mildew indoors. I am NOT sponsored by them, its real recognize real. Organic and safe up to harvest. This stuff is the last thing you'll need to buy. Especially indoors.
