Premium Thrip Killer Sachets - Amblyseius swirskii


Number of Sachets

Premium thrip killer sachets contain the predatory mite Amblyseius swirskii. This predatory mite feeds on multiple stages of thrip larvae present on the plant foliage itself.

Each sachet contains 250 predators which are slowly released onto the plant over 4 weeks. This provides extended protection against thrips and can be used as a method of preventing outbreaks.

For severe infestations of thrips, sachets should be supplemented with loose Amblyseius cucumeris or Amblyseius swirskii to help knock numbers back quickly. Adult thrips can also be targeted with the predator Orius laevigatus for an all round solution.

Delivery Note; 1-2 day lead time on dispatch

Why Amblyseius swirskii is superior to Amblyseius cucumeris

Our premium Amblyseius swirskii outperforms the alternative Amblyseius cucumeris given suitable conditions. The Swirskii predators will kill larger stages of thrip larvae than Cucumeris meaning they eliminate larger amounts of a pest population. Swirskii mites will also consume whitefly eggs giving additional protection.

What conditions do Amblyseius swirskii need?

Amblyseius swirskii are active at temperatures over 20 degrees and are tolerate to high temperature environments.

How long do the predators last?

Each sachet contains around 250 predators and acts as a breeding site for these numbers to multiply before coming out onto the plant. The sachets last around 4 weeks and should then be replaced to keep a steady flow of predators on the plant.

How many sachets do I need?

We recommend applying the sachets at a rate of 1-2 per plant. Based on an average plant 1m in height, with a low to medium infestation of thrips.

How do I apply the sachets?

Each sachet comes with a handy hook which can be placed on plant stems or leaves straight away. There is a pre formed hole ready to release the predators which will make their way out in a steady stream over the 4 week cycle. You can also tear open the sachets and sprinkle directly onto the plants but this will reduce the life cycle to around 2-3 weeks. 

Can I store the sachets?

Unfortunately due to the 4 week life cycle you cannot store the sachets for later use.

 

Please Note; Amblyseius swirskii is a living creature and can be affected by any chemical pesticides used within the previous few weeks. As a guide cease using pyrethrum or SB plant invigorator 2 days prior to use and other persistent chemicals or universal bug killers 1-2 weeks before using predators.
