Garden pest plague Central West NSW

Postby Treoleileagh » Wed Nov 16, 2016 8:08 pm

Last year these things reached plague proportions here and this year it's shaping up like there might be even more of them. They seem to breed in the ground in warmer months and make their ways to flower heads, eating berries and leaves on their way. They are very selective though. They love hollyhocks and lupin leaves, while they dine on rose, salvia and foxglove flowers but not their leaves. They often get around in pairs tail to tail.
As a follow up question how can I get rid of them without injuring bees and birds?
Thankyou for any advice

They are most likely be Harlequin bugs. They can be controlled by shaking them off plants into soapy water, or if an insecticide is to be used be aware that CARBERYL can be used but NOT ON EDIBLE PLANTS. IMIDACLOPRID is also available but again not on edible plants. It is essential you wear gloves when handling them as they give off an awful smell which is hard to get rid of. Perhaps Google the two insecticides I have mentioned to get full details of it's use. We have them here in Tasmania as well
