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.

We use soap all the time to kill insects but at a lesser concentration. It appears quite deadly to a variety of bugs.

Digital, I think it takes a stronger concentration for lily beetles. They're tough.

Thanks, Jacob.

There are organic spray available. My experience with my garden was they will go away without killing them after you spray the organic repeller

Janet Ursel said...

Sunduvan, which spray are you using?

Insects have a system of tubes, called tracheae, instead of lungs. These tracheae penetrate right through the insect's body. Air enters the tracheae by pores called spiracles. These spiracles are found on each side of the insect's abdomen.

The oil and soap will clog up the holes and should do the trick.

Danf things just keep coming back.

I'll have to give that a try. Sounds super simple.
