Small, slender insects about 2-3mm long when fully grown. The adults have two pairs of narrow wings fringed with long hairs, the wings are held along the back when at rest.

Colours range from pale yellow to black, dependant on species.

Thrip Damage

Thrips feed on cell sap by piercing the leaf or flower bud with their mouthparts.These tissues then become mottled or flecked and are subject to dehydration, in severe cases they appear to have been scorched.

When leaves or buds expand they may become distorted or torn, forming "Windows" in the tissue.


Thrips can often be found in large groups near the veins on the under-side of leaves.

Thrip Life Cycle

A single female can lay about 60 eggs throughout the summer. Eggs are laid on the underside of leaves.

The larval stage lasts for about 10-14 days, after which the larva falls to the ground to pupate beneath the soil surface.

The pupal stage lasts between 4 to 7 days.

Thrips Pest Solution

Amblyseius (Pronounced: AM-BLI-SAY-US) are small very active predatory mites, about 1mm long, pale brown in colour with slightly flattened pear shaped bodies, their eggs are white.

Amblyseius are used to control thrips by growers in commercial horticulture.

Amblyseius Life Cycle

Amblyseius adults produce several eggs a day and are quite long lived. Both the adults and young mites eat thrips and may also eat young spider mites.

Amblyseius Usage

  • Amblyseius requires a temperature of 18C (64F).
  • Amblyseius should be introduced to the greenhouse/conservatory on the day of receipt.
  • Amblyseius are sensitive to long hot dry spells, so damping down or misting can help at these times.
  • Amblyseius sachets should not be placed in direct sunlight or near to heating pipes.
  • Like all Defenders biological controls, Amblyseius is harmless to children, pets and wildlife and will not become a pest in its own right.

Biological Thrip Control Product Details

We supply Amblyseius in sachets known as "breeder" packs where the mites are mixed with bran. These "breeder" packs are simply hung among your plants. A food supply for Amblyseius is also contained in the sachet, and it is therefore possible to introduce them to the crop before thrips numbers have built up.
