Is there any deterrent for the lily beetle or is it just a case of keeping vigilant and squashing the little red devils when you see them? Thank you
Being vigilant is key to keeping the lily beetles from ruining your lilies! However, we also suggest the following:
1) Spray with Imidcloprid and sunflower oil (or Bayer Provado Ultimate Bug Killer).
2) If you do not like using insecticides then spraying with diluted fairy liquid or crushed garlic in water have been suggested. Crush a whole corm of garlic in a small pan of boiling water. Allow to cool, strain and put in a small container in the fridge. When using, dilute three parts water to one part garlic solution. Spray often, every few days, especially when it has rained. There is a garlic product available in garden centres and stores, but this is a much cheaper alternative.
3) More recently, a customer has tried planting their lily bulbs alongside a garlic and this has been quite successful in keeping these creatures away.
4) Alternatively, we have been advising our customers to spray their lilies with NEEM oil to eradicate the lily beetle!
Hope one of these suggestions will help you to keep your lilies looking as lovely as they should.
