Fungus Gnat Predator (Hypoaspis sp.)
A tiny brown predatory mite which lives in the soil.
The female lays her eggs in the soil in the area
that the fungus gnats as well as springtails and thrips
live. The nymphs and the adults both feed on these soil dwelling
pests. A very short life cycle of about 10 days means
that you should apply several times for best control. For maximum control use with beneficial nematodes like Bio -Pest -B-Gone

Black Scale Parasite (Metaphycus helvolus)
An other parasitic wasp that is very effective against
several soft scale species including brown scale. Most
effective in semi-tropical conditions.

a tiny parasitic wasp that attacks
Praying Mantis (Tenodera sp.)
The Chinese mantis was first introduced into the United
States in 1896. The mantis captures, holds and devours many
different pests; bothers some insects as well
as beneficials. A very helpful insect in the
vegetable garden or around the house if controlled; otherwise it
can cause damage to the beneficial
populations as well. Used mostly in science projects in schools. OK for indoor use.

a parasitic wasp, attacks armored scales females including
California red scale, yellow scale, San
Jose scale and Oleander scale.

Whitefly Predator (Delphastus pusillus)
a tiny black ladybug which just loves whitefly eggs!
The most abundant and important predators for a
healthy garden are the two-winged Flies,
the Wasps and the Green Lacewings. Parasites will
attack insects in all stages of their
development. The host does not die
immediately but provides nourishment until the larva of the parasite is nearly grown, after which the host dies.
These predators prey on a wide variety of
insect species. They lay their eggs in the host body, which provides
the young with a source of food. Compsilura concinnata is a
fly that was imported from Europe to combat the gypsy
moth. Flesh flies have varied
habits: Some are flesh eaters, while others eat only insects.
More about Wasps
Wasps feed mostly on other insects. Their favorites are caterpillars such as the armyworm.
There are many varieties of parasitic wasps. Wasps
are generally quite social, with males, females and sterile workers
making up the family. Some species of parasitic wasps
attack only certain insects.

nematodes and simulate naturally
occurring soil organisms. They should be tilled into the soil
before planting, and then applied every year after that. They also can be
used as a side dressing as needed.
