Good Bugs and Bad Bugs
To create the perfect growing environment for your Hydroponics project, and to ensure the optimum growing conditions to produce a beautiful, tender, dirt-free, flavorful product.
Although bringing in good bugs to eliminate a bad bug problem might not always solve the problem, you might have to resort to a pesticide. In cases like this, our staff is very educated and can direct you to the best product to use.
When possible, it is always recommended to use these guys to fend off the "Bad Bugs" that might take home in your hydroponic garden. The important thing to remember is that these bugs are a protector of your plants and you do not want to eliminate them.
The Good Ones...
Aphid Predators
Each Aphid Predator larva must eat 10 aphids to reach full development, but will happily eat many more if they are available. Great for indoors because they do not fly toward the light. For a small indoor garden, one release of 100-250 predators will get you started.
White Fly Parasites
Many commercial green-houses use Whitefly Parasites as their only whitefly control. These eggs are glued to small cards and shipped ready to hatch and parasitize pest larvae. Use 500 parasites up to four times to control whitefly infestations in a small home greenhouse.
Ladybugs
An adult Ladybug can eat thousands of aphids and other pests in its lifetime. Good for small and large areas.
Green Lacewing
This excellent all-purpose garden predator devours aphids, mealybugs, soft scale, whiteflies and the eggs of other insects such as spider mites and thrips. Shipped as eggs, these beneficials are best applied 5,000 eggs per acre.
House Fly Parasites
Controls many species of flies by killing their pupae before flies hatch. In its 3-4 week lifecycle, each parasite kills 50 flies. Use anywhere nuisance flies breed. Release 5000 every two weeks for a large compost pile or 3-4 head of livestock.
Mealybug Predators
Predators of small insects, these tiny black ladybugs are effective, proven beneficial insects that have been used commercially for over 100 years. They really enjoy mealybugs but will eat aphids and scale when the mealies get scarce. Apply 2-5 per infested plant or one for every two feet of planted area. Repeat about twice a year as needed.
Pirate Bugs
Pirate Bugs (Orius insidiosis) are used on many crops to control thrip, aphid, spider mite and whitefly populations. Release 5-10 per 100 square feet. For extreme thrip infestations, use in conjunction with Thrip Predators.
Praying Mantis
A Praying Mantis can grow to be four inches long in just one season and will feed on almost any insect it can overcome. Allow several weeks of warm weather for hatching
Spider Mite Destroyers
Spider Mite Destroyers breed twice as fast as spider mites and eat up to five mites or 20 mite eggs every day! Over time, your spider mite populations will dwindle. To control spider mites in six weeks, estimated use is one predator for every 20 spider mites.
Whitefly Predators
Whitefly Predators are fast eaters; they eat one whitefly larva in just 30 seconds. Imagine what these hungry helpers can do for your garden as they munch up to 600 whitefly eggs every day! 300-500 predators cover 1,000 square feet. To use, just shake the predators out of their package onto plant foliage. Predators do best between 65-90 degrees
Fungus Gnat Predator
Nature's alternative to chemical insecticides, Fungus Gnat Predators feed on the larvae of fungus gnats and other small soil-dwelling creatures including thrips, mites, and springtails. Five thousand predators treat up to 200 square feet of growing surface
Predator Mites
Predator Mites usually gain control of spider mite infestations after 4 weeks. Release 100 mites per 25 square feet. Predator mites will be effective in a wide variety of conditions: from 55-90 degrees Fahrenheit and from 45-90% relative humidity.
Thrip Predators
These predators feed on immature thrips (soil and leaf pupating) and an occasional spider mite as well. Use 100-500 per plant or 200,000 per acre to control thrip infestations. For maximum effectiveness, humidity must remain between 70% and 85%.
Beneficial Nematodes
Beneficial Nematodes control over 250 different insects in the soil, including weevils, loopers, borers, moths, and fleas. They are harmless to earthworms and leave plants alone. Not to be confused with pest nematodes, beneficial nematodes are parasitic, and invade the bodies of their prey, leaving behind the dead insect carcasses. One batch fits onto a small, 2" sponge and will cover up to 2,000 square feet. To use, submerge the sponge in water and soak into soil with a watering can or pressure-sprayer. Nematodes may also be injected into borer holes with a syringe. If necessary, Beneficial Nematodes may be stored in the refrigerator (40-50 degrees F) for up to 2 months.
Watch Out For These Guys
Aphids
Description: They are very small with light colored bodies. They leave a sticky residue on the leaves.
Treatment: Remove damaged leaves, wash plant leaves with warm water for a week then spray an insecticidal soap onto leaves.
Caterpillars

Treatment: Pick off by hand.
Cockroaches
Description: Small dark colored insects with beetle like bodies.
Treatment: Pick off by hand if you can catch them. Remove any organic debris from the base of the plant. Set out roach traps.
Cutworms
Description: Small worm type insects that curl up into a ring shape. They eat through plant roots and topple the plant.
Treatment: Not too common in hydroponics - if found, spray with insecticide.
European Corn Borers
Description: Small, 1 inch long caterpillars who bore into plant stems and eat them from the inside out.
Treatment: Spray with insecticide.
Fungus Gnats
Description: The hatched offspring of tiny black flies. The maggot offspring attack plant roots.
Treatment: Discard any damaged plants, spray with insecticide. Not too common in a hydroponics garden.
Leaf Hoppers
Description: Small, 1/8 inch long, wedge shaped insects that suck the sap through the plant leaves.
Treatment: Pick off by hand and apply insecticide if needed.
Mealybugs
Description: Small bugs create white, powdery masses on leaf stem joints.
Treatment: Scrape off and spray with insecticide.
Root Maggots
Description: Fly larvae that hatch at the base of the plants and eat the roots.
Treatment: Not too common in hydroponics gardens. If found, spray with insecticide.
Scale
Description: Tiny waxy growths on the underside of leaves and on stems.
Treatment: Scrape off and isolate plant, if possible. Wash leaves with warm soapy water and apply insecticide if needed.
Striped Cucumber Beetle
Description: Small, very destructive, striped back beetles 1/4 inch long. As adults, these plant pests eat leaves, and as larvae eat roots.
Treatment: Use insecticidal soap.
Tarnished Plant Bugs
Description: Small beetles about 1/4 inch long with tarnish-like markings on it's back. They inject plants with a substance that deforms leaf tips and stem joining.
