Please Note: All our biological pest control options are special order items since they are alive and would rapidly loose effectivity if stored for longer than a few days. Due to this, Predators are ordered specially for you from the manufacturer so there is a slower delivery on this item with an average lead time of 7 days.

What Are Spidex Predator Mites?

Spidex Predator Mites is a Spider Mite predator larvae product aimed at attacking spider mite infestations.

Spider Mite nymphs (young) and adults feed on plant cells, removing chlorophyll, which is necessary for the plant to maintain proper metabolic processes. Yellowing of the leaf will occur in smaller infestations, while plants may die in the worst cases.

Predator Mites are the natural enemy of spider mites. They feed on spider mites, reducing numbers until all mites are killed, at which point the predatory mites migrate off the plant.

What Do Spidex Predator Mites Target?

Spidex Predator Mites target the common two spotted spider mite (Tetranychus urticae). They attack all stages, but prefer the younger mites.
The predatory mite can only survive on two spotted spider mites (Tetranychus spp.).

Storage and handling
Biological Beneficial’s have a very short life expectancy and therefore need to be introduced into the crop as soon as possible after receipt. Storing them for a period can have a negative impact on their quality and is only possible under the conditions described below. Koppert B.V. is not liable for any loss of quality if the product is stored for longer than recommended and/or under incorrect conditions.

Mode of action
Adult predatory mites and nymphs search actively for their prey and suck them dry.

Visual effect
Adult red spider mites that have been eaten change colour from brown to black (in tomato) and can be identified as tiny black dots on the leaves. This should not be confused with living, light-brown to dark-red spider mites.
