Thrip Pest Control

1. Thrip
Hi, my name is: Thrip
Describe yourself: About 2mm long, sometimes white and yellow but don’t mind black. Quite slim,
with lovely fringed wings! Don’t be fooled, what I lack in size I make up for in tenacity. I’m very
social and usually travel with lots of mates.
Hobbies: Laying eggs in unopened flowers, sucking sap, spreading viruses from plant to plant.
Likes: Most plants, but really fond of tomatoes, beans, roses, azaleas and fruit trees. I love any
white or light-coloured flowers!
Dislikes: Soaps – like home made chilli soap, or store bought stuff. Don’t get along with Ladybirds
or Lacewings.
You’ll know you’ve met me when: Your plants’ leaves look white and a bit mottled, the petals or
fruit turn brown, and flower buds fall off! Late spring is my favourite time to visit your garden – just
as the roses start to bloom!.
Old School Control Methods: Confidor, Rogor or Malathion.
If you want to dump me, you could try to:
Irritate me by putting a flattened square of aluminium foil around the base of plants to bounces

2. light on the undersides of leaves.
Drench me with a forceful jet of water in the early morning for 3 consecutive days.s
Spray me with a home made garlic or chilli soap. Or use a store bought insecticidal soap. Ands
target the underside of leaves where I usually like to shelter.
Prevent my adult friends from emerging from leaf litter in the early spring by applying a thick layers
of organic mulch around susceptible plants.
Remove damaged plant parts as I also like to over winter in plant tissue or bark fissures.s
Hit me with a pyrethrum spray if I JUST WON”T LEAVE, but be careful not to use when friendlys
pollinating insects are visiting the same flowers!
Deter me by cultivating the soil around your plants in autumn to a depth of 6 cm and again in thes
following spring.
Destroy all infected flowers and buds but don’t compost them. Throw them out – and me withs
them!
