Help! Any idea what’s going on with my white ghost cactus? He was in the shade mostly and I have just switched him to more sun in the last week so I’m hoping that will help?! It looks almost like rust on the bottom

That looks like scale to me. Try scraping one off to see if it’s a bug.

If so, should I try to use 100% isopropyl alcohol?

#### Monさんが2024-07-07に返信しました

Yes, but you will have to remove them by scratching them off. It won’t be as easy as just spraying. I use 70% alcohol. Make sure to put it in the shade for a couple of days. Alcohol will make it burn.

Ugh sounds taxing. Will they overtake my plant and kill it if I don’t do this asap?

#### Monさんが2024-07-07に返信しました

Not asap. You can wait a few days. Also, there are heavier pesticides that would require less work. You could research if you would like to take that route. I don’t have much experience

I’ve had scale on my aloe and I used bonide horticultural oil on it to kill them ☺️

#### Lindsayさんが2024-07-08に返信しました

Did it work? And do the red spots go away?

#### Urban Jungle 🦩さんが2024-07-08に返信しました

Yes it worked and it cleaned the plant too, I didn’t scrape them off. I had less than you do though
