Canola Oil Insecticide
Canola Oil Insecticide is a great cure for your gardens creepy crawlies particularly Mites and Aphids but most of your slow-moving Insects.
As I mentioned in Organic Pesticides, Canola Oil can be used straight out of the Pantry at the rate of 2% in water (20mls/L).
It works the same as White Oil but is a lot easier on the plant while being just as hard on the Pests.
The Canola Oil suffocates the Insect as well as breaking down the outer shell of the Pest bringing about their permanent demise.
Canola Oil Insecticide is available as a Spray for Commercial Farming operations, it is an accepted Organic Insecticide with its use becoming more and more widespread.
Below are a series of Photo's that show step by step the easiest way to use Canola Oil as an Organic Insecticide.
1; Grab a can of Aerosol Canola Oil, nothing special just an of the shelf variety.
2; Site your Target, here Woolly Aphids thick and fast on an Ornamental
3: Spray said Woolly Aphids, the Canola Oil foams a lot, don't overdo it, spray enough to just cover the Bugs.
4; Come back the next day and view your victory, sticky dead Pests.
If you have Pests on "soft" plants be careful as you have to with any Oil Insecticide, test spray a small area first to make sure they don't wilt.
Canola Oil as an Insecticide works very well on Roses; as soon as you see the first Mites or Aphids appear just give them a tickle up with the Aerosol Canola Oil before they take hold.
Works a treat!

For long term residual control use regular liquid fish fertiliser as a foliar spray, another method if your plant is an ornamental is a soil drench with Neem Oil. Cheers, Barry

Christina, I find the best preventative is regular liquid fish fertilizer or if your plant is an ornamental a soil drench with Neem Oil is a great long term residual method. Cheers, Barry

Okay, but after doing this, how do you recommend getting rid of the bug carcasses? Also, can this be done pre-emptively?
Barry Gregory
Hi Christina, There are two ways of getting rid of the carcasses, wipe them off with either a damp cloth or paper towel or just wash them off with your garden hose. Cheers Barry
