Another way to get rid of lily beetles

Joyce sent me an email with her solution for killing lily beetles. She says it works on both the adults and the larvae.

She takes one cup (250 mL) cooking oil, 1/2 cup (125 mL) Sunlight dish detergent, puts them in a one-litre bottle and fills it up with water. She sprays the insects directly and reports that they die within seconds.

I haven't tried it myself yet, but if I did, I would be watching to see if there are any negative effects on the plants too. While this spray sounds like it certainly would kill just about any insect on contact, it might be a bit intense for at least some plants.

If you try it, let me know what kind of results you get.

And thanks, Joyce, for sharing your spray recipe with me.
