You released predatory mites. Now give yourself a useful record of what happens to the pest problem.
Photograph a few affected leaves and note the date, the pest being treated, and where fresh damage appears. Those same areas will give you something to compare with later, without relying on your memory of how the whole plant looked.
Keep the comparison consistent
Revisit the affected foliage and nearby growth. Follow confirmed pest activity, fresh webbing where relevant, and whether new areas develop damage. Record uncertain observations as uncertain and ask for identification help when needed.
For flying pests such as thrips and whiteflies, appropriately placed sticky cards can provide another record. Compare equivalent periods with the cards in consistent positions. A card follows flying stages; it does not describe every stage elsewhere on the plant.
Old damage stays
Feeding scars and stippling can remain after pest activity declines. Compare newly developing injury with your earlier photographs, and watch new growth when the plant is actively growing. A plant that is not producing leaves can still be assessed by changes in pest activity and damage on existing foliage.
Respond to the pattern
There is no single deadline for every predatory mite, pest, and growing environment. Follow the species-specific release guidance and reassess promptly if the infestation or plant condition worsens.
Review pest identification, treatment coverage, temperature and humidity around the plants, and recent pesticide use. Another release may be appropriate, but first address problems that could prevent the treatment from succeeding.
Questions about the shipment
Contact FGMN promptly with your order number and photographs of the packaging if you have concerns about the delivery. Keep sachets intact and follow the supplied release instructions.
