Identification card icon Identification

Soil-dwelling mite Stratiolaelaps scimitus (Hypoaspis miles) is a native species, which feeds on thrips (prepupa and pupa), fungus gnats, root scales, root aphids, mealybug crawlers, spider mites in greenhouses, hydroponic and mushroom crops. This product is perfect for an in-depth “cleaning” of the soil before starting the season.

This voracious mites have also been recommended as a biological alternative for poultry red mite (Dermanyssus gallinae) and for the reptile mites (Ophionyssus spp) in tropical and semi-tropical habitat.

Adults are light brown and less than 1 mm long. They move quickly at the soil’s surface. After mating, the female lays eggs in the growing medium. Juveniles are also predators and feed on the small pest they find in the soil.

Targeted crops

stratiolaelaps scimitus (hypoaspis miles)

Sprinkle Stratiolaelaps scimitus directly on the ground. It can live in different types of substrate such as potting soil, coconut fiber, rock wool, etc. In indoor production, this predator is known to establish well in crops planted directly on the ground or in potted plants. Stratiolaelaps scimitus is easy to establish and helps maintain permanent pressure on pests until the cold of winter. A single introduction is generally sufficient at the start of the season.

Compatible with other soil biocontrol agents such as Dalotia (Atheta) coriaria, beneficial nematodes , and with entomopathogenic fungus-based bio-insecticides such as BioCeres.

Chicken Mites

Bological control against red poultry mites

The red poultry mite (Dermanyssus gallinae) is a parasite that feeds on the blood of birds. It feeds on the animal at night and, after feeding, hide in cracks and crevices away from light sources, where they mate and lay eggs. Red poultry mites are found around the chests and legs of birds. The buildup of bites can cause irritation and reduced egg production. Once properly established, red mites are difficult to get rid of. They can even survive for up to 10 months in an empty chicken coop.

To prevent the apparition of red poultry mites or reduce their numbers, introduce the predatory mite Stratiolaelaps scimitus directly to the places where these parasites are the most present (on the ground, corners, nests, cracks, and the underside of perches). This natural predator lives on the ground, in the soil, in cracks and crevices where it actively searches for new prey to eat. It hates the light and can attack all stages of the red poultry mite.
