Tracey submitted the following:
"I had been informed at a Master Gardener meeting last year that the application of coffee grounds around the base of the lilies helped to deter these little pests, as they are attracted to the odour left by previous infestations. The coffee supposedly masks the smell. I have been visiting my local Starbucks regularly and obtaining used coffee grounds. I have been sprinkling them about once a week around my lillies and with a fair amount of success. To date I have counted five of them only, and when I find them, I kill them and then apply horticultural oil to the plants to kill the eggs and larvae. I haven't seen any in over a week and I check daily for infestations. My garden is in Oshawa, Ontario."
And Bonita had a great idea for those of you finding it hard to get down on your knees to search for eggs and larvae (and we know how easily lilies can snap if you bend them too much to look under the leaves):
"A 'stick mirror' makes it much easier to see eggs under the leaves, than getting down on your hands and knees."
