Woolly Aphid (aka Mealy Bug) Infestation

The Woolly aphids (also known as mealy bugs) that infested my indoor jade plant have also had a go at my outdoor hydrangea. It was covered in them. It also was covered in some sort of sooty mould. It really was a bad case so I decided the only remedy was to cut the bush back and put the branches in the council green bin (I didn’t want all those aphid eggs going in my compost). I then drenched the remaining stumps with a spray made up of kitchen veggie oil (against the aphids) and bi-carb (against the mould). Actually I sprayed the surrounding ground/foot path as well. It’s all black and grimy and aphids rained down on me (*shudder*) and the ground as I worked. (A long hot shower immediately followed.)

I’ve been doing some research and there are some other options beyond my normal garlic spray (I haven’t started any since returning so it’s no help as it takes a couple of weeks to brew nicely). I’m going to try adding tabasco (tea tree oil is another option) to my oil/soap/bi-carb mix.

As if this wasn’t all enough – my 2 new citrus trees both had their own infestations (one was normal aphids and one was some sort of scale). After hand squashing/removing what I could, I sprayed them with an oil spray.

This has been a VERY wet summer and I’m thinking that must be a perfect environment for these garden pests. I’ll have to keep spraying regularly because eggs are still there to hatch, but I will get on top of this infestation!

    Although the post is old, your last photo was a perfect match for what I found on a houseplant so thank you for helping me identify the enemy.

    Wooly aphids and mealy bugs are two different insects.
