Amblyseius cucumeris - Sachets - Thrip Preventative System

Number of Sachets

Amblyseius cucumeris are small predatory mites that feed on thrip larvae and their eggs. They feed mainly on the small or first instar larvae of Western Flower thrip (Frankiniella occidentalis).

Each predator will consume many thrip young and eggs, moving around the plant and flowers in search of their prey.

Amblyseis will feed on flower pollen which allows their introduction before pests are present. With predators on the plant at all times, any news signs of thrip will be killed before they can take hold. Each sachet will release fresh predators for 3-4 weeks. We advise using these sachets as part of our preventative system rather than as a cure for heavy infestations.

If thrip is present in large numbers already (signs of leaf damage and numerous thrip) we advise switching to our curative system. This consists of loose Amblyseius swirskii and loose Amblyseius cucumeris applied together every 7-10 days until control is achieved.

Please ensure you have read the appropriate conditions for using cucumeris before purchase, these can be found below.
