Avocado Pest: Cottony Cushion Scale

Last weekend, I took big the avocado tree out to the porch to give it a thorough watering. Its tips are turning brown and I’m worried its due to a build up of salt in the pot from too small waterings. Nate noticed some little white fuzzy things on some of the branches….

….hmmm…

Nate’s pest ID app said it was a kind of scale – probably cottony cushion scale. This is a scale insect that has a large white (“cottony”) egg sac that can grow up to half an inch long. I’m guessing I got this pest when I brought the citrus that was summering on the porch back inside for the winter. I was sooo careful about checking for pests! And even now, I don’t see any evidence of cottony scale on any of the other plants – just this one avocado.

I sprayed the whole plant with Neem oil (it’s an indoor plant, so I’m not that worried about hurting off-target insects). It’s only been a week, so it’s too early to say, but it’s not looking any worse.
