Amblyseius swirskii Sachets - Target Pests

What Swirskii Sachets Protect Against

Thrips, Caught Young

Western flower thrips, onion thrips, melon thrips and chilli thrips, taken as young larvae before they can grow and multiply.

Whitefly, Before It Builds

Eggs and young nymphs of greenhouse whitefly and tobacco (silverleaf) whitefly.

Small Plant-Feeding Mites

Broad mites, cyclamen mites, russet mites and some other small mites. Swirskii also eats two-spotted spider mites at low numbers, but sachets won't control an established spider mite problem; for that, use Phytoseiulus persimilis or Neoseiulus californicus.

When Pests Get Ahead of the Sachets

Sachets are for prevention. If numbers climb:

• Add bottled swirskii for a fast dose of predators.
• Bring in Orius insidiosus, a faster-acting predator that also eats adult thrips.
• For whitefly, add Encarsia formosa for greenhouse whitefly or Eretmocerus eremicus for hot spaces and tobacco whitefly.
