Fungus gnats are typically the small, slow flying gnats you find gracefully flying around plants that have been overwatered or are unhealthy, or simply from contaminated soil you purchased. Although the adults are relatively harmless, the larvae of fungus gnats are actively feeding on the plants’ roots. This can expediate the decline of the plants’ health and eventually aid in killing the plants.

Fortunately, Stratiolaelaps scimitus is an excellent predator to fungus gnats and one application for the life of the plant should be all that is needed to eradicate the infestation and prevent further infestations from arising.

Two-spotted spider mites will enter a “red phase” when they go into diapause, most often triggered by day length.  When they do, they need to find a place to “hibernate”, which is typically down in the soil. In greenhouses, they often utilize ground penetrations like plumbing or posts to easily get down to a safe depth for this vulnerable stage of their life.

Fortunately for growers, Stratiolaelaps scimitus will easily locate and feed upon these spider mite refuges.  For growers in greenhouses, it is recommended to give a 25ml scoop of Stratiolaelaps scimitus media to each ground penetration, and then broadcast the remaining product along the floors of the greenhouses during the off-season.  This will give next season’s crop a huge advantage.

Symphylans typically consume decaying vegetation, but can do considerable harm in agriculture by feeding on seeds, roots, and root hairs.

Thrips are a common pest.  Like spider mites, their damage is quite visible and permanent, which can be devastating for some crops.  In a thrips life-cycle, their pupation occurs in soil. This is where they’re most vulnerable and eaten by Stratiolaelaps scimitus.  Research shows a grower can see an 80% reduction of thrips by only using Stratiolaelaps scimitus in the soil.

Root weevils’ eggs are usually the only stage of their lives that are small enough to be consumed by Stratiolaelaps scimitus, but trials have indicated it is enough to break the cycle and give years of control.

Or woodlice.  Wikipedia: Although woodlice, like earthworms, are generally considered beneficial in gardens for their role in controlling pests,[35] producing compost and overturning the soil, they have also been known to feed on cultivated plants, such as ripening strawberries and tender seedlings.[36]

Woodlice can also invade homes en masse in search of moisture and their presence can indicate dampness problems.[37] They are not generally regarded as a serious household pest as they do not spread disease and do not damage sound wood or structures.

Woodlice have many natural predators, some specialized predators, and are seldom a major pest problem.  But for those times when they do target your plants, Stratiolaelaps scimitus is one of the naturally occurring predators that can remedy the problem.

Like fungus gnat larvae, Root Aphids suck the life out of your plant through the root.  Being soft-bodied aphids in the soil, they’re an easy prey for Stratiolaelaps scimitus. Get Stratiolaelaps scimitus in early in the crop, ideally at propagation, to keep on-top of pest populations like these, so they never have the opportunity to stunt or damage your plants.

Like root aphids, if these get into high-enough numbers they can kill your plant.  And like root aphids, they are easy targets for Stratiolaelaps scimitus. Get the Stratiolaelaps scimitus into the pots as soon as planting or seeding to get a head-start.

Decades ago, researchers found that Stratiolaelaps scimitus is an excellent control method for bulb mites.  The Stratiolaelaps scimitus will make their way into and around the bulbs and eliminate the bulb mites.

There is quite an elaborate Wikipedia page on Springtails: https://en.wikipedia.org/wiki/Springtail  

Stratiolaelaps scimitus feed on and control Springtails.  Due to the abundance of Springtails all over the world, it is in many ways thanks to Springtails that low levels of Stratiolaelaps scimitus can be maintained in your garden once they have eradicated the target pests, and can remain established for years to come.

Beneficial or not, nematodes are very sensitive to humidity and temperature and need to live within that small window to remain alive/established, typically no longer than 1 month outdoors.  Typical pest nematodes found in garden are common targets for Stratiolaelaps scimitus.

Beneficial nematodes can be used to knock down a heavy pest infestation, but it is always much more economical to use Stratiolaelaps scimitus as they persist for multiple years, as opposed to weeks.
